K24551552 : Apache Tomcat vulnerability CVE-2019-17563

Security Advisory Description

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. (CVE-2019-17563)

Impact

Under certain circumstances, a race condition in Tomcat allows session fixation, potentially allowing a local attack to access another administrative user’s session.
