Descriptions

When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0 to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an attacker could perform a session fixation attack. The window was considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has been treated as a security vulnerability.

Cuando se usa la autenticación FORM con Apache Tomcat 9.0.0.M1 hasta 9.0.29, 8.5.0 hasta 8.5.49 y 7.0.0 hasta 7.0.98, había una ventana estrecha donde un atacante podía llevar a cabo un ataque de fijación de sesión. La ventana fue considerada demasiado estrecha para que una explotación sea práctica, pero, por precaución, este problema ha sido tratado como una vulnerabilidad de seguridad.

It was found that tomcat's FORM authentication allowed a very small period in which an attacker could possibly force a victim to use a valid user session, or Session Fixation. While practical exploit of this issue is deemed highly improbable, an abundance of caution merits it be considered a flaw. The highest threat from this vulnerability is to system availability, but also threatens data confidentiality and integrity.
