Description

The vulnerability allows a remote attacker to inject HTTP header on the target system.

The vulnerability exists due to insufficient validation of user-supplied input. A remote unauthenticated attacker can trick the victim into clicking on a malicious link and use integrated web server (Port 80/TCP and Port 443/TCP) inject HTTP headers.

Mitigation
