Local privilege escalation via OS command injection
Published Aug 17, 2026 · Updated Aug 17, 2026
OS command injection in Dell ObjectScale before 4.3.0.1 allows local users with low privileges to escalate privileges. Dell identifies improper neutralization of command elements but does not disclose the affected proprietary component or unsafe shell operation. Exploitation requires local low-privilege access and runs attacker-controlled commands with elevated privileges on the affected system.
