HCL BigFix AEX: Remote code execution via command or code injection
Summary
HCL BigFix AEX, an AI assistant that runs alongside BigFix endpoint management, is affected by a vulnerability classified as OS command injection (CWE-78) and code injection (CWE-94). According to the CVE record, an attacker could execute code with the privileges of the affected application or service, which could lead to unauthorized access, data exposure or system compromise. The CVSS 3.1 base score is 9.1 (critical), but the vector requires high privileges and the vendor description does not name the affected component, so the rating is provisional.
Affected
- HCL BigFix AEX v13.0.0.1 (per CNA record; other versions unknown)
Fixed in
Unknown. Check vendor advisory KB0134281 for fixed builds.
Workaround
Unknown. No vendor workaround has been confirmed. Until the advisory is read, restrict network access to the AEX component and limit who holds privileges needed to reach it.
Exploitation
- Not known to be exploited (OffSeq).
- Not listed in CISA KEV (Strix).
- No public proof of concept found.
- EPSS: 0.46% (percentile 40).
Our recommendation
- Check whether any BigFix AEX 13.0.0.1 instance is in use.
- Read advisory KB0134281 for fixed builds and workarounds, and apply the fix when available.
- Until a fix is installed, restrict network access to AEX and review privileged accounts.
- Monitor the NVD entry, which is still pending analysis.
