"The version of Tomcat installed on the remote host is prior to 10.1.61. It is, therefore, affected by multiple
vulnerabilities as referenced in the fixed_in_apache_tomcat_10.1.61_security-10 advisory.

  - A missing critical step in authentication vulnerability in Apache Tomcat when the JNDI realm was
    configured with with a non GSSAPI SASL authentication mechanism allowed attackers to authenticate without
    providing the correct password. (CVE-2026-101296)

  - Incorrect object recycling and re-use affecting HTTP/2 processing of asynchronous servlets can trigger
    request and/or response mix-up between users. (CVE-2026-101356)

  - Incomplete cleanup vulnerability in Apache Tomcat allowed an trailer information from a previous request
    to leak into a subsequent request. (CVE-2026-88041)

    (CVE-2026-93446)

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