"The Veritas NetBackup application installed on the remote Windows host is prior to 8.3 and may be missing a vendor-supplied
security hotfix. It is, therefore, affected by multiple vulnerabilities:

  - An attacker with local access can send a crafted packet to pbx_exchange during registration and cause a
    NULL pointer exception, effectively crashing the pbx_exchange process. (CVE-2022-42308)

  - An attacker with local access can delete arbitrary files by leveraging a path traversal in the pbx_exchange
    registration code. (CVE-2022-42306)

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