Apache Tomcat 11.0.0.M1 < 11.0.6 multiple vulnerabilities

high Nessus Plugin ID 235032

Language:

Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities

Description

The version of Tomcat installed on the remote host is prior to 11.0.6. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_11.0.6_security-11 advisory.

 - Improper Input Validation vulnerability in Apache Tomcat. Incorrect error handling for some invalid HTTP priority headers resulted in incomplete clean-up of the failed request which created a memory leak. A large number of such requests could trigger an OutOfMemoryException resulting in a denial of service. This issue affects Apache Tomcat: from 9.0.76 through 9.0.102, from 10.1.10 through 10.1.39, from 11.0.0-M2 through 11.0.5. Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6 which fix the issue. (CVE-2025-31650)

 - Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat. For a subset of unlikely rewrite rule configurations, it was possible for a specially crafted request to bypass some rewrite rules. If those rewrite rules effectively enforced security constraints, those constraints could be bypassed. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.5, from 10.1.0-M1 through 10.1.39, from 9.0.0.M1 through 9.0.102. Users are recommended to upgrade to version [FIXED_VERSION], which fixes the issue. (CVE-2025-31651)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 11.0.6 or later.
