  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2026-24734
Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat. When using an OCSP responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not complete verification or freshness checks on the OCSP response which could allow certificate revocation to be bypassed. This issue affects Apache Tomcat Native:  from 1.3.0 through 1.3.4, from 2.0.0 through 2.0.11; Apache Tomcat: from 11.0.0-M1 through 11.0.17, from 10.1.0-M7 through 10.1.51, from 9.0.83 through 9.0.114. The following versions were EOL at the time the CVE was created but are known to be affected: from 1.1.23 through 1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected. Apache Tomcat Native users are recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which fix the issue. Apache Tomcat users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115 or later which fix the issue.

Summary
  • (es) Vulnerabilidad de validación de entrada incorrecta en Apache Tomcat Native, Apache Tomcat. Al usar un respondedor OCSP, Tomcat Native (y el puerto FFM de Tomcat del código de Tomcat Native) no completó las verificaciones de verificación o frescura en la respuesta OCSP, lo que podría permitir que se eluda la revocación del certificado. Este problema afecta a Apache Tomcat Native: de 1.3.0 a 1.3.4, de 2.0.0 a 2.0.11; Apache Tomcat: de 11.0.0-M1 a 11.0.17, de 10.1.0-M7 a 10.1.51, de 9.0.83 a 9.0.114. Las siguientes versiones estaban al final de su vida útil (EOL) en el momento en que se creó el CVE, pero se sabe que están afectadas: de 1.1.23 a 1.1.34, de 1.2.0 a 1.2.39. Las versiones EOL más antiguas no están afectadas. Se recomienda a los usuarios de Apache Tomcat Native que actualicen a las versiones 1.3.5 o posteriores o 2.0.12 o posteriores, que solucionan el problema. Se recomienda a los usuarios de Apache Tomcat que actualicen a las versiones 11.0.18 o posteriores, 10.1.52 o posteriores o 9.0.115 o posteriores que solucionan el problema.
