Fixed In Version: tomcat 7.0.99, tomcat 8.5.50, tomcat 9.0.30
Doc Type: If docs needed, set a value
Doc Text:
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.

Description Guilherme de Almeida Suckevicz 2019-12-20 18:30:26 UTC
When using FORM authentication 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.
