CVE-2024-50379: Apache Tomcat Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability

December 17, 2024 (updated January 3, 2025)

Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability during JSP compilation in Apache Tomcat permits an RCE on case insensitive file systems when the default servlet is enabled for write (non-default configuration).

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.0.97.

Users are recommended to upgrade to version 11.0.2, 10.1.34 or 9.0.98, which fixes the issue.
