7.0.0.43, 8.0.0.x prior to 8.0.0.13, or 8.5.0.x prior to 8.5.5.10. It is, therefore, affected by an XML external entity
injection vulnerability in the Apache Standard Taglibs subcomponent due to an incorrectly configured XML parser
accepting XML external entities from an untrusted source. An unauthenticated, remote attacker can exploit this, via
specially crafted XML data, to execute arbitrary code on the system.

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