  - Improper limitation of path names in Veeam Backup & Replication 9.5U3, 9.5U4,10.x, and 11.x allows remote
    authenticated users access to internal API functions that allows attackers to upload and execute arbitrary code.
    (CVE-2022-26500)

  - Veeam Backup & Replication 10.x and 11.x has Incorrect Access Control. (CVE-2022-26501)

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