ABB PCM600 can import files outside intended folder

CVE-2026-15953 · published 1 month ago
Summary

The ABB Protection and Control IED Manager (PCM600) lets an attacker place specially crafted archive files that, when imported, can write to any location on the system instead of only the designated import directory. This could let unauthorized users modify or replace critical files, potentially disrupting operations. Update the PCM600 software to the latest version or apply the vendor’s recommended patch to enforce proper folder restrictions.
