Local privilege escalation via writable update script
Published Sep 14, 2023 · Updated Feb 27, 2025
Improper permissions in Siemens Spectrum Power 7 before 23Q3 allow local users to inject code into an update script and escalate privileges. The product assigns access rights to the update script that permit an authenticated local user to alter it with arbitrary code. Successful exploitation requires authenticated local access and executes attacker-supplied code with higher privileges, affecting confidentiality, integrity, and availability.
