Apache Tomcat 9.0.13 < 9.0.117 Multiple Vulnerabilities

high Web App Scanning Plugin ID 115217

Synopsis

Apache Tomcat 9.0.13 < 9.0.117 Multiple Vulnerabilities

Description

The version of Apache Tomcat installed on the remote host is 9.0.13 prior to 9.0.117, 10.1.0-M1 prior to 10.1.54 or 11.0.0-M1 prior to 11.0.21. It is, therefore, affected by multiple vulnerabilities :

- An error in the fix for CVE-2026-29146 allowed the EncryptInterceptor to be bypassed. (CVE-2026-34486)

- CLIENT_CERT authentication does not fail as expected for some scenarios when soft fail is disabled and FFM is used. (CVE-2026-34500)

- The cloud membership for clustering component exposed the Kubernetes bearer token in log messages. (CVE-2026-34487)

- Incomplete escaping when non-default values were used for the Connector attributes relaxedPathChars and/or relaxedQueryChars allowed the injection of arbitrary JSON into the JSON access log. (CVE-2026-34483)

Note that the scanner has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 9.0.117 or later.
