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 7.3.x prior to 7.3.1 Hotfix 290316 (7.3.1.125), 7.4.x prior to 7.4.1 Hotfix 291882 (7.4.1.58), or 7.5.x prior to 7.5.0 Hotfix 291881 (7.5.0.183). It is, therefore, affected by a missing access control check vulnerability. A remote unauthenticated attacker could read or change the Local Download Service (LDLS) credentials.
