Some vulnerabilities have been reported in the Horde Application Framework, which can be exploited by malicious people to conduct script insertion and cross-site scripting attacks and by malicious users to compromise a vulnerable system.
1) An error within the form library when handling image form fields can be exploited to overwrite arbitrary local files.
Successful exploitation requires that an application uses the affected image fields (e.g. Ansel or Turba) and that the attacker has write permissions.
2) An error exists within the MIME Viewer library when rendering unknown text parts. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site if malicious data is viewed.
3) The preferences system does not properly sanitise numeric preference types. This can be exploited to execute arbitrary HTML and script code in a user's browser session in contact of an affected site.
Solution: Update to version 3.2.5 or 3.3.5 or apply patches.
