Technical details
This is a reflected cross-site scripting (XSS) vulnerability in O2OA v10's Forum posting function. The vulnerability exists because user-supplied input from URL parameters is not properly sanitized or HTML-encoded before being reflected in the response. An attacker can craft a malicious URL containing JavaScript payload that, when visited by an authenticated user, executes arbitrary code in the context of the victim's browser and authenticated session. The attack requires social engineering (convincing a user to click a malicious link) but does not require prior authentication by the attacker. Patch availability for this vulnerability is not specified in the advisory.
