Cookie manipulation Security Vulnerability

Description
By injecting a custom HTTP header or by injecting a META tag, it is possible to alter the cookies stored in the browser. Attackers will normally manipulate cookie values to fraudulently authenticate themselves on a web site.

Impact
By exploiting this vulnerability, an attacker may conduct a session fixation attack. In a session fixation attack, the attacker fixes the user's session ID before the user even logs into the target server, thereby eliminating the need to obtain the user's session ID afterwards.
