Technical details

An Incorrect Permission Assignment (CWE-732) vulnerability exists in the firmware of Schneider Electric EasyLogic T150 and Saitel DP Remote Terminal Units (RTUs). The flaw resides in improperly protected system files that store sensitive authentication data. An attacker with local, high-privileged access (PR:H) can read these files to extract password hashes. These hashes can then be subjected to offline brute-force or dictionary attacks to recover plaintext credentials, leading to potential account compromise. The vulnerability is addressed in the latest security notices from Schneider Electric.
