RHSA-2025:3455

A flaw was found in Apache Tomcat. In certain conditions and configurations, this vulnerability allows a remote attacker to exploit a path equivalence flaw to view file system contents and add malicious content via a write-enabled Default Servlet in Apache Tomcat. For the vulnerability to be exploited, the following conditions must be true: writes to the default servlet are enabled (disabled by default), sensitive file uploads are sub-directories of a target URL for public uploads, attackers know the names of the files, and those files are subject to partial PUT uploads enabled by default. If an application uses file-based session persistence with default storage and includes exploitable libraries, remote code execution (RCE) is possible.
