Missing CSRF protection
Published
E-mail alert when it lands in KEV, gets a public PoC or its score goes up.
No sign of exploitation. No public exploitation artifact known so far.
OTRS authentication cookies lack proper security settings in HTTPS connections, allowing malicious websites to steal user sessions and perform unauthorized actions. This happens because the cookies don't have protections that prevent them from being sent to untrusted sites.
The OTRS Application Server fails to set SameSite and Secure attributes on authentication cookies, enabling CSRF attacks where a malicious site can trigger requests that include valid session cookies. An attacker can perform unauthorized read operations by crafting requests from a compromised web page visited by an authenticated OTRS user.
In the same product, most dangerous first.
