Description
uBB.threads is vulnerable to a Cross-Site Request Forgery (CSRF) due to a lack of protective mechanisms. This allows an attacker to trick an authenticated user into executing unintended actions. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.
