CVE-2023-28006

Password security compromise via MD5 hashing

Published Jun 22, 2023 · Updated Dec 5, 2024

Weak cryptography in HCL BigFix OSD Bare Metal Server before 311.12 allows local users to cause unspecified impact via MD5. The affected password-security path relies on MD5, but HCL has not published the storage or verification operation that consumes it. Exploitation requires local low-privileged access and no user interaction; no concrete post-compromise behavior is publicly documented.
