Description

The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

Google Chrome before 4.0.211.0 cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-the-middle attackers to overwrite or delete arbitrary cookies via a Set-Cookie header in an HTTP response, related to lack of the HTTP Strict Transport Security (HSTS) includeSubDomains feature, aka a "cookie forcing" issue.

Mitigation

Install update from vendor's website.

Vulnerable software versions
