"The version of QNAP QTS / QuTS hero installed on the remote host is affected by a vulnerability as referenced in the
QSA-23-22 advisory.

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of
    Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within
    the dsi_writeinit function. The issue results from the lack of proper validation of the length of user-
    supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this
    vulnerability to execute code in the context of root. Was ZDI-CAN-17646. (CVE-2022-43634)

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