  • AhsayOBS (v6), AhsayOBSR (v6), AhsayCBS (v7/v8), AhsayOBM (v7/v8), AhsayACB (v7/v8), AhsayUBS (v6/v7/v8) are not vulnerable to CVE-2021-44228 (Log4j vulnerability).

      While the Log4j binaries exist, the version of Log4j Ahsay products bundled does not contain the JNDILookup plugin and is not one of the affected versions.
      Related, applicable only for AhsayCBS v8.5.4.86+, the remote logging feature and all logging had been disabled for Log4j Logger (set to OFF).

      However, pre-v8.5.4.86 AhsayCBS versions may be vulnerable to other vulnerabilities not associated with this CVE. There are critical vulnerabilities with certain Ahsay versions, as described in Ahsay Security Advisory (#26030)

      NOTE: If you are running any earlier version than the current release, it is highly advised to CBS Administrators to stay up to date and upgrade to the most recent release. There may have been fixes for other critical bugs or vulnerabilities that have since been patched, we are unable to relist each past CBS version's history here, but you can refer to each version's Release Notes on Ahsay Wiki.

  • AhsayPRD 2.0 is not vulnerable.
  • Ahsay Mobile 1.6+ is not vulnerable.
  • AhsayMOB is EOL and unsupported.

EOL Reminder:

For v7.x, starting on 2021-06-30 Ahsay announced that Version 7 is progressively desupported and will EOL on 2022-01-01. No further enhancements, development, or hotfixes will be created.

For v6.x, on 2018-07-16 Ahsay announced that Version 6 is EOL 2018-12-31. No further enhancements, development, or hotfixes would be made.
