A weakness and two vulnerabilities have been reported in DotNetNuke,
which can be exploited by malicious users to enumerate files on an
affected system and bypass certain security restrictions and by
malicious people to conduct cross-site scripting attacks.
1) Certain unspecified input passed via DotNetNuke.RadEditorProvider is not properly sanitised before being used to check for the existence of certain files. This can be exploited to enumerate e.g. .resources or .config files.
This weakness is reported in versions 6.0.0 through 6.1.2.
2) Certain input passed via the URL is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
This vulnerability is reported in versions 6.0.0 through 6.0.2.
3) An error within the authorization for certain user management functions can be exploited to e.g. create new users, delete users, and edit existing users and roles.
This vulnerability is reported in versions prior to 5.6.7 and prior to 6.1.3.
