CVE-2026-4832Network attack vector

Device information disclosure via hard-coded SNMP credentials

Published Apr 14, 2026 · Updated Apr 14, 2026

Hard-coded credentials in Schneider Electric Easergy MiCOM Px40 relay firmware allow remote attackers to read device information over SNMP. The SNMP service accepts a credential embedded in affected firmware and uses it to authorize queries that expose basic device identification. Reachability of the SNMP port is sufficient; Schneider Electric reports confidentiality impact only and no ability to modify relay data or interrupt protection.
