CVE-2025-6519Network attack vector

Unauthenticated administrator access via predictable daily password

Published Sep 2, 2025 · Updated Sep 2, 2025

Predictable credentials in Copeland E3 Supervisory Control before 2.31F01 allow remote attackers to obtain administrator access. The immutable ONEDAY account receives a newly generated password each day, but its credential generation is predictable; public sources do not disclose the algorithm. Network access to the web-accessible application services is sufficient, and successful login grants administrative control over facility systems.
