CVE-2007-3822

Description:
Christopher Schwardt has reported multiple vulnerabilities in WebCit, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site request forgery and cross-site scripting attacks.
1) WebCit allows users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited to e.g. modify certain settings or create new rooms, tasks, and responses by enticing a user to visit a malicious site.
2) Input passed via entries in the "calendar" or "bulletin board" mode, the room name, the filename of uploaded files, and preferences is not properly sanitised before being used. This can be exploited to insert arbitrary HTML- and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.
Successful exploitation requires user credentials, but can potentially be exploited in combination with vulnerability #1.
3) Input passed to the "who" parameter when showing users 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.
The vulnerabilities are reported in versions prior 7.11.
Solution:
Update to version 7.11.
