Root command execution via SMIME recipient deletion
Published Sep 29, 2026 · Updated Sep 29, 2026
OS command injection in IBM Guardium Data Protection 12.2 allows remote authenticated users with privileged CLI access to execute root commands. The certificate SMIME recipient-deletion CLI path accepts input that reaches an OS command without adequate neutralization; IBM has not disclosed the specific argument or command construction. Exploitation requires a privileged CLI account, and successful commands run with root privileges on the appliance.
