Credential disclosure via crafted packet privilege error
Published Feb 13, 2024 · Updated Aug 2, 2024
Incorrect privilege assignment in all MELSEC iQ-R Safety and SIL2 Process CPUs allows remote authenticated users to disclose credentials. The vendor has disclosed only that a specially crafted packet returns a lower-privileged user's ID and password; the affected packet field and faulty authorization operation remain undisclosed. Access requires login to the CPU module as a non-administrator, and disclosure is limited to accounts below the attacker's access level.
