System component modification via writable root filesystem
Published May 6, 2026 · Updated May 6, 2026
Security misconfiguration in HCL BigFix Service Management 23 allows remote authenticated users to modify the root filesystem. The deployment leaves the root filesystem writable instead of enforcing a read-only mount, permitting changes to critical components. Exploitation requires administrative privileges, high complexity, and user interaction; published evidence does not establish host escape or persistence outside the affected environment.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
