ABB Ability OPTIMAX: Incorrect Implementation of Authentication Algorithm
CVE-2025-14510 is a high-severity incorrect implementation of authentication algorithm vulnerability in ABB Ability OPTIMAX from ABB, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 6.3.1-251120, 6.4.1-251120 as the first without the flaw, so updating ABB Ability OPTIMAX to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.43% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update ABB Ability OPTIMAX to 6.3.1-251120 or 6.4.1-251120, whichever matches your release line, or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
