"The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in
the CONFSERVER-104610 advisory.

  - ** UNSUPPORTED WHEN ASSIGNED ** Deserialization of an inbound SOAP fault in Apache Axis 1.x allows
    unauthenticated remote class instantiation. When a SOAP <Fault> carries a <detail><exceptionName> element,
    Axis loads the named class and, if a String <data> element is also present, instantiates it through its
    String constructor before checking that it is an AxisFault. Loading alone runs the class's static
    initializer. With a suitable class on the application's classpath this leads to remote code execution. The
    fault is parsed while the engine resolves the target service, before any per-service handler chain runs,
    so authentication handlers configured on a service do not protect against it. This affects all Apache Axis
    1.x versions through 1.4. As Axis 1 has been EOL we recommend you migrate to a different SOAP engine, such
    as Apache Axis 2/Java. Alternatively you could use a build of Axis with the patch from
    https://github.com/apache/axis-axis1-java/commit/41f3b4e8d04e310ca81f86b92630ab2c11d608bd applied. The
    Apache Axis project does not expect to create an Axis 1.x release fixing this problem. (CVE-2026-90436)

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