A flaw was found in RESTEasy in all versions of RESTEasy up to 4.6.0.Final. The endpoint class and method names are returned as part of the exception response when RESTEasy cannot convert one of the request URI path or query values to the matching JAX-RS resource method's parameter value. The highest threat from this vulnerability is to data confidentiality.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - resteasy: Error message exposes endpoint class information (CVE-2021-20289)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The version of resteasy-base installed on the remote host is prior to 3.0.6-4. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2398 advisory.
