"The remote Debian 11 / 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5544
advisory.

  - Authorization Bypass Through User-Controlled Key vulnerability in Apache ZooKeeper. If SASL Quorum Peer
    authentication is enabled in ZooKeeper (quorum.auth.enableSasl=true), the authorization is done by
    verifying that the instance part in SASL authentication ID is listed in zoo.cfg server list. The instance
    part in SASL auth ID is optional and if it's missing, like '[email protected]', the authorization check will
    be skipped. As a result an arbitrary endpoint could join the cluster and begin propagating counterfeit
    changes to the leader, essentially giving it complete read-write access to the data tree. Quorum Peer
    authentication is not enabled by default. Users are recommended to upgrade to version 3.9.1, 3.8.3, 3.7.2,
    which fixes the issue. Alternately ensure the ensemble election/quorum communication is protected by a
    firewall as this will mitigate the issue. See the documentation for more details on correct cluster
    administration. (CVE-2023-44981)

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