A medium-severity improper-authentication vulnerability in the checkSysPwd function of com/ahsay/obs/api/ApiStructsAction.java in AhsayCBS versions up to 10.3.2. Attackers are actively chaining it with CVE-2026-105134 to obtain unauthenticated remote code execution, deploy JSP webshells, and install XMRig cryptominers. Huntress observed exploitation beginning October 7, 2026, at 23:20:15 UTC.
A remotely exploitable improper authentication vulnerability in the AhsayCBS API affects versions up to 10.3.2. Manipulating the random argument in the checkSysPwd function triggers the flaw. A public exploit is available, and upgrading to version 10.3.4 mitigates the issue.
An authentication bypass in AhsayCBS's API component, specifically the checkSysPwd function in com/ahsay/obs/api/ApiStructsAction.java. Manipulating the random argument permits unauthorized access to protected API functionality; the content explicitly distinguishes this access from command execution. The reported CVSS score is 7.3. Public exploit code is available, and AhsayCBS 10.3.4 fixes the flaw. Network segmentation, restricted management access, and API-focused WAF rules are recommended compensating controls.
