CVE-2024-9877

Password disclosure via GET query strings

Published Apr 30, 2025 · Updated Apr 30, 2025

Information exposure in ABB ANC, ANC-L, and ANC-mini 1.1.4 and earlier allows attackers to read plaintext passwords from local network traffic. The web HMI places passwords in HTTP GET query strings, exposing them to any party able to observe requests to the affected services. No authentication or user interaction is required, but the attacker must be able to read traffic on the local network; integrity and availability are unaffected.
