Fixed issue with displaying a module on all pages. A malicious user must Microsoft released an To fix this problem, you can vulnerability. No member-only profile properties are exposed if all profile properties are set to member-only or admin. DNN has provided several update {databaseOwner}{objectQualifier}ModuleControls Although the config file will receive a new Last Modified Date as a result of this exploit, the content of the config file can not be viewed, downloaded, or arbitrarily modified. sites where single users administrate all the content are not affected. In this case the hacker could point it to an untrusted source. To fix this problem, you are recommended to update to the latest version of DotNetNuke (3.3.4/4.3.4 at time of writing). Code has been added to close this authentication blindspot. 1. When performing an installation or upgrade DotNetNuke forces the application to unload and reload so that changes can be processed. The potential hacker must induce a user to click on a URL that contains both the location of a trusted site and a redirect to an untrusted site. The feature allows scripts to post messages User may think that the message is coming from the site itself, as opposed to the malicious user. malicious user may be able to perform XSS attacks. Longer‐term, refinery capacity growth is expected to outstrip crude production growth. Mitigating factors User can choose to fill several profile properties such as first name, last name, profile picture, etc. Please note, you will also have to remove the existing FTB editor and associated dll's i.e. This only affects sites where users are granted "edit" permissions i.e. A particular piece of malformed HTML was not correctly detected by this code, and the potential for a persistent cross-site scripting (XSS) attack could occur. However, the backdoor detection method proposed in NC relies on a clean training dataset that does not contain any maliciously manipulated data points. The code that handles this supports selecting the folder but fails to revalidate these permissions. It was possible to avoid the existing URL filtering code by using invalid URL's. It is only truly removed after the recycle bin has been emptied. from Microsoft, there is a need to update this assembly in DNN sites. initiate XSS attacks on sites which contain old SWF files. For versions older than 9.1.1, you can download a typo such as "pssword"), a hacker with physical access to a machine may be able to access the cached page and gain help in guessing a password. This could allow a malicious user to execute Javascript or another client-side script on the impacted user's computer. The code has been refactored to filter the input to ensure that cross-site scripting attacks cannot occur. They are only suitable for the dnn 3.3 & 4.3 builds since the CSS files and code within the ASCX file has the references to create the menu, which I've tested in Firefox, Opera & IE. To fix this problem, you are recommended to update to the latest version of DNN (7.4.2 at time of writing). Cross-site scripting (XSS) vulnerability in DotNetNuke (DNN) before 7.4.0 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. Newly Installations configured using the ‘Secure’ folder type would not have the file contents disclosed. Whilst the W3C specification for this tag states that it will not work unless it is in the HEAD of the document, testing found that it does work within the BODY in a number of major browsers. During the process of rewriting the code to extend the Profile component, an issue was introduced where a user had the ability to inject javascript on the Role management page. DNN thanks the following for working with us to help protect users: The DNN Framework contains code to allow internal messaging of users. Then they must submit crafted requests to target this vulnerability. affected. For sql server databases, the user must supply the servername and database. User can add JavaScript to the Biography by including the following payload: 456. To fix this problem, you are recommended to update to the latest version of DotNetNuke (7.4.1 at time of writing). However, this information is also potentially helpful to hackers, so the OS identification functionality was removed. If your site contains a controlled set of users i.e. Mitigating factors. Products - DNN Platform 9.0.1 or EVOQ 9.0.1 at the time of writing. To support URL Rewriting, DotNetNuke determines the current path of the page and echoes it to the form action attribute to ensure that any actions post to the correct page. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. DNN Platform Versions 9.0.0 through 9.2.2. To fix this problem, you are recommended to update to the latest version of DotNetNuke (4.5.4 at time of writing). content designed to exploit the vulnerability. To remediate from this issue an upgrade to DNN Platform Version (9.3.1 or later) is required. To fix this problem, you are recommended to update to the latest versions of the Product release 9.2.0, All DNN sites running any version from 7.2.0 to 9.1.1. To protect against attacks that attempt to use invalid URL's, users can install the free Microsoft URLScan utility(https://www.iis.net/downloads/microsoft/urlscan). The full list of 3rd party components in use can always be found in the "Licenses" folder. This approach is seen throughout the DNN administrative interface, and is intended to be used similarly in custom module development. Based on analysis of IIS logs from affected sites, this bug was being used by spammers to create large numbers of new accounts at at time. DNN has code to ensure that these redirects are always to valid locations and not to untrusted external locations. (phishing). The user profile module supports templating so these properties are optional. And a setting name "AUM_SSLClientRedirect" with value "Y" must be in the host settings table in database. Some of these calls were be subject file path traversal. A number of browsers incorrectly implement a particular HTML tag, in violation of the official W3C standards. The malicious user must know the specifics of the SVG to initiate such attacks and must lure registered site users to visit the page displaying the uploaded SVF file. The more you know the more there is to know, that is life. A malicious user can send However one usage was found in a 3rd party module so we have chosen to create this bulletin to make users aware. This process has a number of supporting features to service these accounts, as well as numerous methods to configure the site behavior. 9.1.1 at the time of writing. A malicious user can send a crafted request to login to a DNN site which uses Active Directory module for users’ authentication and cause high CPU usage in the server which can lead to a Denial of Service (DOS) attack. Due to a weakness is validating the user identity it is possible for a potential hacker to access other user's account leading. It's not needed while using Trusted Connection. The core already implements HttpOnly cookies to stop XSS attacks potentially stealing authentication cookies. The code that provides for this upload does not filter sufficiently for valid values. the site to malfunction. A malicious user must know which API to utilize and send a specially crafted request to the site. Once accessed these functions allowed for the uninstalling of modules, or installation of modules. Only DotNetNuke sites that have multiple language pack installs and use the Language skin object suffer from this flaw. Whilst these files are necessary for installation/upgrade of DNN, they are left behind after the process finishes. To fix this problem, you are recommended to update to the latest version of DNN (7.4.1 at time of writing). The code for the user messaging module does not sanitize all entered text, meaning it would be possible to generate a message that contained a script or html vulnerability. As … Check your web.config file. SVG image files can contain CSS and more importantly, JavaScript, Some DNN sites allow users to upload certain files to their sites. A DNN/Evoq installation must be configured in a specific manner and the malicious user would need specific knowledge to leverage the vulnerability. Anonymous user can discover some or most of the profile properties from a DNN site due to a vulnerability present in DNN. DotNetNuke contains a number of layers of protection to ensure that one user cannot execute actions as another user. Known limitations & technical details, User agreement, disclaimer and privacy statement, DNN (aka DotNetNuke) before 9.1.1 has Remote Code Execution via a cookie, aka "2017-08 (Critical) Possible remote code execution on DNN sites.". To protect against attacks that attempt to use invalid URL's, users can install the free Microsoft URLScan utility(http://www.iis.net/expand/UrlScan). When users are attempting to access portal functions, we strive to strike a balance between providing informative messages, but not revealing unnecessary detail to people attempting to profile the application. An unauthenticated user in specific configurations could construct a payload that would result in a stored scrip being executed at a later time by a user with elevated permissions. under the same copy of the dotnetnuke code in IIS. DotNetNuke has a number of user management functions that are exposed both for users and administrators. This XSS is not stored but rather reflected as part of the request - in addition DotNetNuke has a number of pieces of defensive code to protect against the targets of common XSS attacks. User may have a valid account to login and must have edit permissions on a page or module. The code for the user profile properties has a bug where an unautheticated user could access member-only properties under certain configurations. files such as images, module & skin extensions, documents, etc. ** UNVERIFIABLE ** Unspecified vulnerability in an unspecified DNN Modules module for DotNetNuke (.net nuke) allows remote attackers to gain privileges via unspecified vectors, as used in an attack against the Microsoft France web site.

This issue only allows for the existence of a file to be confirmed and does not allow the file to be read or altered. A malicious user needs The lists module does not correctly sanitize the name(s) of list/sublists - this can lead to a reflective cross-site scripting (XSS) issue. be uploaded within the Portals folder only; it cannot be uploaded outside of Cross-site scripting (XSS) vulnerability in Website\admin\Sales\paypalipn.aspx in DotNetNuke (DNN) before 4.9.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors related to "name/value pairs" and "paypal IPN functionality.". In sites with certain configurations, a malicious user might be able to discover certain information regarding the existence of user accounts within the installation. 2. If you’ve setup a new DNN site running on version 9.0 or 9.1, you’ll notice that you don’t have the ability to setup the Google Analytics module/code anymore. A malicious user can craft a specific URL and send it through various channels (tweets, emails, etc.) A poor design pattern in the validation code meant that it was possible for potential hackers to access both the install and uninstall functions via a user who did not have host permissions. into DNN’s folders. This process could overwrite files that the user was not granted permissions to, and would be done without the notice of the administrator. In addition the path is likely to be easily guessable e.g. if the installwizard can be forced to load, the potential hacker must provide valid database connection details. One needs to know the exact way to obtain this information. NOTE: An upgrade will NOT automatically resolve this issue. INDIRECT or any other kind of loss. Background writing. When a site contains a custom 404 error page is used, an anonymous user can receive limited rights to the previously logged in user in certain cases. Download it again. If a user re-registers with the same username/password combination as an existing account, they are undeleted. Some site configure IIS to listen to all incoming traffic on port 80/443 and be directed to a single DNN instance hosted under IIS which serves multiple web sites simultaneously. Alternatively, add specific bindings to the sites (DNS names) being served in that instance of DNN in IIS pool instead of directing to all incoming requests to this site. Fixed issue with Event Log Email Notifications. In the simplest terms, the DNN 9.0.2 patch closes a vulnerability where the DNN registration form data could leak into an unauthorized user’s hands. So I will keep this dialog going until I give up and close or submit a PR. did not honor the permission specified for them and they could be accessed Fix(s) for issue The language skin object failed to encode the newly generated paths which meant that a hacker could inject html/script to perform cross-site scripting attacks. 3 - To establish the causes of the vulnerability of vulnerable students and to propose appropriate solutions. Alternative 2: Log in as the host user, and go to the host->sql menu, paste the following script into the textbox, and check the 'run as script' checkbox, /* fix security issue with vendor management */ Note: Whilst not a mitigation, the identification of the operating system of a website is a trivial action with a number of websites/tools offering tools which probe and identify operating system's accurately. displayed. When attempting to access a a page that the user does not have permission to, the user is correctly redirected to the login page. sub-system of DNN, which is not very critical to the operation of DNN. HTML5 is cross-document messaging. A prior security bulletin was published (2018-13) and a fix implemented in DNN Platform & Evoq 9.2.2. a potential hacker must have access to a html module editor instance, a user must be using a browser that incorrectly implements the previously discussed behaviour, user must have module or page editor permissions, user must have access to the lists function - by default only admin and host users can access this module, user must have access to a member directory module, member directory module must be available to all (including anonymous) users, the site must allow users to post to other users journals. This value is an implicitly trusted URL, so it is possible for a hacker to publish a url to your site that already contains this querystring parameter. As the information is important it will still show if the versions differ, but if they are in sync which is the normal case, the version is not revealed. To fix this problem, you can DNN allows several file This vulnerability can only be exploited by users with a valid username/password combination on a website. Have you already implemented a site using the DNN . Homepage of the Enhanced Web Development Service with information about the service and help for portal administrators one of such cookies and identify who that user is, and possibly impersonate This is the recommended manner to guarantee file security for confidential documents as it is the only method that provides a secure file check at download. When sending a message it is possible to upload/send a file. This could be used as the basis to gain unauthorised access to portal files or data. to other windows. To fix this problem, you are DNN Platform 9.6.0 was released with 3.5.0 included, and 9.6.1 was released with jQuery 3.5.1 after they released an urgent update. If a user could then be fooled into clicking on that link, a reflective XSS issue would occur A malicious user with specific knowledge of the exploit may add or edit files within the file system, without explicitly being granted permission. To fix this problem, you are recommended to update to the latest version of the DNN platform (7.2.0 at time of writing). (e.g. www.mysite.com). A failure to detect certain input as malicious could allow a hacker to use a cross-site scripting attack to execute html/javascript. Anti-forgery token called RequestVerificationToken is used in DNN Web APIs to help prevent Cross-Site Request Forgery (CSRF) attacks. In 6.0 DotNetNuke introduced folder providers as an abstraction to support alternative file stores, replacing the existing filesystem code. A malicious users can in very specific cases upload images on behalf of a registered user. All submitted information is viewed only by members of the DNN Security Task Force, and will not be discussed outside the Task Force without the permission of the person/company who reported the issue. upload malicious code to a site which gives them the ability to take control of DNN fully supports this notion and A failure to verify the anti-forgery token can mean a CSRF issue occurs. Cross-site scripting (XSS) vulnerability in the Language skin object in DotNetNuke before 4.8.4 allows remote attackers to inject arbitrary web script or HTML via "newly generated paths.".

Extract the plugin zip and copy the folder to dnn CKEditor Plugins folder (..\Providers\HtmlEditorProviders\DNNConnect.CKE\js\ckeditor\4.5.3\plugins) Because html5video plugin has dependencies (widget,widgetselection,clipboard,lineutils) , so need to download those plugins and copy them to dnn CKEditor Plugins folder as well. Only a few Web APIs were To remediate this issue an upgrade to DNN Platform Version (9.4.1 or later) is required. This attack can be made as anonymous user also. Whilst this code filters for common XSS issues, a variant was found that could bypass the filter, so additional protection was added. Fixed issue with Event Log Email Notifications. DNN contains a CMS file. 2. The issue is only visible with very specific configurations within the DNN Platform, and the exploit would require specific knowledge to exploit. 1. When a module is deleted within DNN Platform it is first moved to the Recycle Bin, for a soft-delete process, allowing restoration. Each Skin set has 2 skins, horizontal menu only at this stage, the vertical is a little more work, but it's fixed and wide skins, and 4 containers each to use. Whilst this parameter is typically encoded, an invalid tag could be used to bypass the filter, potentially to unencoded content being echoed to the screen and could allow for script or html injection issues. Further information on phishing can be found here. upgrade to the latest versions of the Products - DNN Platform 9.1.1 or EVOQ The upgrade process It is imperative that when removing a provider that backups are made and that all files are removed. For the 3.3.3/4.3.3 releases of DotNetNuke, the membership/roles/provider components were significantly overhauled to allow better granularity of control, and to allow us to make a number of enhancements. A malicious user with a properly constructed URL, and an DNN installation with a specific configuration could allow an injected javascript code to execute. 2. DNN Platform contains multiple JavaScript libraries that provide functionality. Theoretically knowning the drive and folder of the website is useful information to a potential hacker so this has been removed. In DNN when a user tries to access a restricted area, they are redirected to an “access denied” page with a message in the URL. Typically we do not provide details of security fixes, as those may only serve to help the potential hackers, but in this case as this fix is not expected to resolve 100% of automated registration issues, some detail is merited. To fix this problem, you are recommended to update to the latest version of DotNetNuke (4.8.3 at time of writing). This only affects sites where the forgot password utility is used. The Exploit Database is a CVE compliant archive of public exploits and corresponding vulnerable software, developed for use by penetration testers and vulnerability researchers. without any authorization. As both of these extensions support filetypes that can contain executable code, this would allow a user to upload dangerous files.
