E3 Supervisory Control: Improper Verification of Cryptographic Signature

Published Updated By the CyberSecBulletin desk

CVE-2025-52550 is a high-severity improper verification of cryptographic signature vulnerability in E3 Supervisory Control from Copeland LP, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 2.31F01 as the first without the flaw, so updating E3 Supervisory Control to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.22% chance of exploitation within 30 days, which is low compared with other CVEs.
