Technical details
A vulnerability classified as CWE-358 (Improperly Implemented Security Check for Standard) exists in Delta Electronics DVP80ES3 firmware versions 1.08.10 and earlier. The flaw resides in the implementation of standard security validation mechanisms within the PLC. A remote, unauthenticated attacker can exploit this over a network (AV:N) without user interaction (UI:N). Successful exploitation primarily impacts availability (VA:H), potentially leading to a denial-of-service (DoS) of the controller. The vendor has addressed this in advisory Delta-PCSA-2026-00009.
