EMC Avamar ADS / AVE 7.2.x < 7.2.1 Hotfix 277897 / 7.3.x < 7.3.1 Hotfix 276676 / 7.4.x < 7.4.1 Hotfix 279294 Multiple Vulnerabilities (ESA-2017-054)
Critical Nessus Plugin ID 101110
SynopsisA backup solution running on the remote host is affected by multiple vulnerabilities.
DescriptionAccording to its self-reported version number, the EMC Avamar Data Store (ADS) or Avamar Virtual Edition (AVE) software running on the remote host is 7.2.x prior to 7.2.1 Hotfix 277897 (188.8.131.52), 7.3.x prior to 7.3.1 Hotfix 276676 (184.108.40.206), or 7.4.x prior to 7.4.1 Hotfix 279294 (220.127.116.11). It is, therefore, affected by multiple vulnerabilities :
- An authentication bypass vulnerability exists that allows an unauthenticated, remote attacker to bypass authentication and gain access to the system maintenance page. Note that this vulnerability does not affect the 7.4.x version branch. (CVE-2017-4989)
- A remote code execution vulnerability exists in the file upload feature of the system maintenance page due to improper validation of file types and extensions of uploaded files before being placed in a user-accessible path. An unauthenticated, remote attacker can exploit this to upload a specially crafted file and then request it in order to execute arbitrary code. Note that this vulnerability does not affect the 7.2.x version branch.
