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

  - Improper Output Neutralization for Logs vulnerability in Apache Log4cxx. When using HTMLLayout, logger     names are not properly escaped when writing out to the HTML file. If untrusted data is used to retrieve     the name of a logger, an attacker could theoretically inject HTML or Javascript in order to hide     information from logs or steal data from the user. In order to activate this, the following sequence must     occur: * Log4cxx is configured to use HTMLLayout. * Logger name comes from an untrusted string * Logger     with compromised name logs a message * User opens the generated HTML log file in their browser, leading to     potential XSS Because logger names are generally constant strings, we assess the impact to users as LOW     This issue affects Apache Log4cxx: before 1.5.0. Users are recommended to upgrade to version 1.5.0, which     fixes the issue. (CVE-2025-54812)

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