Local privilege escalation via writable installed executables
Published Jul 17, 2026 · Updated Jul 17, 2026
Incorrect file permissions in HCL DFMPro 4.1, DFXAnalytics 3.1, and DFXServer 3.1 installers allow local users to replace executables. The installers assign executable files permissions that permit a logged-in non-administrative account to overwrite or replace them with attacker-controlled binaries. Exploitation requires local low-privileged access and user interaction; execution of the substituted binary has limited confidentiality and integrity impact.

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.
