Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient input validation when parsing cookies. A remote attacker can send a specially crafted HTTP request with a cookie value that starts with a double quote and force the application to read the cookie string until it sees a closing quote. Such behavior can be used to exfiltrate sensitive values from other cookies.

Mitigation
Install updates from vendor's website.
