Device cold start via memory dump overread
Published Feb 11, 2025 · Updated Feb 12, 2025
Out-of-bounds read in the memory dump function in all Siemens APOGEE PXC and TALON TC versions allows attackers to force an insecure cold start. The memory dump function reads beyond its intended buffer, and the resulting fault drives the controller into a cold-start state that interrupts normal operation. Exploitation requires network reachability, high attack complexity, and Medium or higher device privileges; Telnet is disabled by default, bounding exposure to enabled or otherwise reachable management paths.

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.
