"The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by a vulnerability as referenced
in the SUSE-SU-2023:4830-1 advisory.

  - Twisted is an event-based framework for internet applications. Prior to version 23.10.0rc1, when sending
    multiple HTTP requests in one TCP packet, twisted.web will process the requests asynchronously without
    guaranteeing the response order. If one of the endpoints is controlled by an attacker, the attacker can
    delay the response on purpose to manipulate the response of the second request when a victim launched two
    requests using HTTP pipeline. Version 23.10.0rc1 contains a patch for this issue. (CVE-2023-46137)

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