"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat. Tomcat did
    not escape ANSI escape sequences in log messages. If Tomcat was running in a console on a Windows
    operating system, and the console supported ANSI escape sequences, it was possible for an attacker to use
    a specially crafted URL to inject ANSI escape sequences to manipulate the console and the clipboard and
    attempt to trick an administrator into running an attacker controlled command. While no attack vector was
    found, it may have been possible to mount this attack on other operating systems. This issue affects
    Apache Tomcat: from 11.0.0-M1 through 11.0.10, from 10.1.0-M1 through 10.1.44, from 9.0.40 through
    9.0.108. The following versions were EOL at the time the CVE was created but are known to be affected:
    8.5.60 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade
    to version 11.0.11 or later, 10.1.45 or later or 9.0.109 or later, which fix the issue. (CVE-2025-55754)

Note that Nessus relies on the presence of the package as reported by the vendor.");
