CVE-2013-6166: Google Chrome

Medium severity, CVSS 6.8. EPSS: 1.9% chance of exploitation in the next 30 days.

Google Chrome before 29 sends HTTP Cookie headers without first validating that they have the required character-set restrictions, which allows remote attackers to conduct the equivalent of a persistent Logout CSRF attack via a crafted parameter that forces a web application to set a malformed cookie within an HTTP response.

Affected products

• Google Chrome: up to and including 28.0.1500.95
