====== Ahsay Security Advisory (#26030) - Critical Vulnerability in AhsayCBS v7 and AhsayCBS v8 ======

We have recently uncovered a critical vulnerability in the AhsayCBS API (Application Programming Interface) system, which exposes some versions of AhsayCBS v7 and AhsayCBS v8 to a very high risk of malicious attack and loss of data.

The vulnerability could potentially allow a malicious attacker to:

  * Gain access the file system and all backup files on the AhsayCBS server
  * Obtain a list of directories and files on the AhsayCBS server
  * Delete files on the AhsayCBS server
  * Download files from the AhsayCBS server

===== What are the affected AhsayCBS versions? =====
  * AhsayCBS pre-v7.17.2.97 
  * AhsayCBS v8.1.0.24 to v8.1.1.x
  * AhsayCBS v8.3.0.30 to 8.3.0.104

===== Does it affect my AhsayOBM/AhsayACB v7 and v8 clients? =====

The vulnerabilities only affect AhsayCBS v7 and AhsayCBS v8 servers, it does not affect the AhsayOBM/AhsayACB v7 and v8 clients, and therefore no action is required for AhsayOBM/AhsayACB clients.  

However, we do recommend partners consider upgrading AhsayOBM/AhsayACB clients to the latest versions to take advantage of the latest available bug fixes and enhancements.

===== What action do I need to take to fix this problem? ===== 

All affected partners: 
  * On AhsayCBS v7 are strongly advised to upgrade to the latest version of v7, AhsayCBS v7.17.2.119 or above to fix the critical vulnerability.
  * On AhsayCBS v8 are strongly advised to upgrade to the latest version of v8, AhsayCBS v8.3.2.11 or above to fix the critical vulnerability.
