Mantis Multiple Input Validation Vulnerabilities

Mantis is prone to a cross-site scripting vulnerability and an arbitrary-script-execution vulnerability because it fails to adequately sanitize user-supplied input.

An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks. Attackers with a valid administrator account may be able to execute PHP code.

Mantis 1.1.1 is vulnerable; other versions may also be affected.
