"The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in
the CONFSERVER-99216 advisory.

  - Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Apache Tomcat. This issue affects
    Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through
    9.0.97. The mitigation for CVE-2024-50379 was incomplete. Users running Tomcat on a case insensitive file
    system with the default servlet write enabled (readonly initialisation parameter set to the non-default
    value of false) may need additional configuration to fully mitigate CVE-2024-50379 depending on which
    version of Java they are using with Tomcat: - running on Java 8 or Java 11: the system property
    sun.io.useCanonCaches must be explicitly set to false (it defaults to true) - running on Java 17: the
    system property sun.io.useCanonCaches, if set, must be set to false (it defaults to false) - running on
    Java 21 onwards: no further configuration is required (the system property and the problematic cache have
    been removed) Tomcat 11.0.3, 10.1.35 and 9.0.99 onwards will include checks that sun.io.useCanonCaches is
    set appropriately before allowing the default servlet to be write enabled on a case insensitive file
    system. Tomcat will also set sun.io.useCanonCaches to false by default where it can. (CVE-2024-56337)

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