Synopsis

A backup solution running on the remote host is affected by a privilege elevation vulnerability.

Description

According to its self-reported version number, the Dell Avamar or Avamar Virtual Edition (AVE) software running on the remote host is 19.4 prior to 19.12. It is, therefore, affected by a privilege elevation vulnerability:

- Dell Avamar, version 19.4 or later, contains an access token reuse vulnerability in the AUI. A low privileged local attacker could potentially exploit this vulnerability, leading to fully impersonating the user. (CVE-2025-21117) Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Dell Avamar version 19.12 or later.
