Summary
Red Hat Security Advisory: tomcat9 security update
Notes
Topic
An update for tomcat9 is now available for Red Hat Enterprise Linux 10.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Tomcat is the servlet container that is used in the official Reference Implementation for the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community Process. Tomcat is developed in an open and participatory environment and released under the Apache Software License version 2.0. Tomcat is intended to be a collaboration of the best-of-breed developers from around the world.
Security Fix(es):
* tomcat: Potential RCE and/or information disclosure and/or information corruption with partial PUT (CVE-2025-24813)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

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\u00a0Default Servlet\u00a0in Apache Tomcat. \n\nFor 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.", "title": "Vulnerability description" }, { "category": "summary", "text": "tomcat: Potential RCE and/or information disclosure and/or information corruption with partial PUT", "title": "Vulnerability summary" }, { "category": "other", "text": "This vulnerability has a Moderate impact (rather than Important) because it requires multiple non-default configurations to be exploitable, significantly limiting its impact in typical deployments. For remote code execution (RCE), exploitation requires both file-based session persistence and a library vulnerable to deserialization, further reducing its likelihood. For information disclosure or file injection, the attack is only possible if writes are enabled for the default servlet, partial PUT requests are supported, and sensitive file uploads occur within a publicly writable directory. The combination of all three of these conditions is uncommon in secure environments. Since most modern Tomcat deployments do not meet all these criteria simultaneously, the overall risk is reduced\n\nThe Tomcat package as shipped in Red Hat Enterprise Linux 6 and 7 is not affected by this vulnerability because the vulnerable code was introduced in a newer Tomcat version.\n\nRed Hat Satellite is not directly impacted by this issue as it does not include the affected Tomcat package. However, Tomcat is consumed by Candlepin, a component of Satellite. Red Hat Satellite users are advised to check the impact state of Red Hat Enterprise Linux as any necessary fixes will be distributed through the platform. Satellite configuration does not contain affected parameters that would make Tomcat vulnerable, therefore, even if a vulnerable Tomcat version is shipped with affected RHEL release alongside Satellite, there is no chance of it being exposed to flaw in Red Hat Satellite.", "title": "Statement" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not
