Synopsis :

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

Description :

According to its self-reported version number, the EMC Avamar Data
Store (ADS) or Avamar Virtual Edition (AVE) software running on the
remote host is a version prior to 7.3.0 Hotfix 268253 (7.3.0.233)
or prior to 7.3.1 Hotfix 272363 (7.3.1.125). It is, therefore,
affected by a local privilege escalation vulnerability due to
incorrect file ownership. A local attacker who has administrative
access can exploit this vulnerability to bypass some sudo command
restrictions and execute arbitrary commands as root, resulting in
gaining elevated privileges.
