DotNetNuke user and profile properties fields support an extended visibility property to determine if fields are available to all, members, friends/followers or admin only. 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. DNN allows registered users to create content on site, where one create a links to other pages on the site. Upgrading to 5.4.0 does not automatically remove these, as there may be many legitmate messages from portal administrators. The DNN Community would like to thank the following for their assistance with this issue. Sites that do not grant these permissions to users, or do not use the freetexteditor implementation of the html editor provider are not vulnerable to this issue e.g. Sites that do not allow public/verified registration also are less likely to have unknown users who can access this vulnerable component, A logical flaw in the permissions checks for modules could allow a potential hacker to use a carefully crafted url to escalate their permissions beyond module edit permissions. The code for the user profile properties has a bug where an unautheticated user could access member-only properties under certain configurations. identifying this issue and/or working with us to help protect users: A malicious user can decode Mitigating factors. DNN provides a user account mechanism that can be used to register users in the system. Whilst the modules would then fail to install fully due to user file permissions, it was possible to access the failed installation and hence run code. A malicious user must know that a DNN site is hosted in an IIS server which is configured to direct to all incoming traffic to this site, and must know what the exact URL to target this sites is. Cvss scores, vulnerability details and links to full CVE details and references (e.g. The user needs to know the actions to reach the error page and must use the computer right after another users has logged out before the session expires. As such these files need to be removed to protect against security profiling. The member directory fails to apply these checks to a number of fields. The product is used to build professional looking and easy-to-use commercial websites, social intranets, community portals, or partner extranets. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. Multiple vulnerabilities have been discovered in DotNetNuke (DNN), which could allow for remote code execution if a file containing malicious code is uploaded. An issue was fixed where a particular URL could lead to a redirect to an external location -in security terms this is known as a "phishing" attack. To remediate this issue upgrading to DNN Platform version 9.4.1 or later is recommended. does not delete these files and they need to be deleted manually. Part of this code fails to sanitize against input and could allow a hacker to use a cross-site scripting attack to execute malicious html/javascript.
