CVE-2024-43659

Cross-device takeover via shared plaintext credentials

Published Jan 9, 2025 · Updated Mar 11, 2025

Credential disclosure in Iocharger AC charger firmware before 25010801 allows attackers to obtain shared super-user credentials. A redacted firmware file stores the same plaintext initial password across all AC models without forcing a change on affected releases. Access requires prior firmware compromise, a file-inclusion path, physical firmware extraction, or another firmware-image source; the credentials then permit authenticated command execution through the System Custom page.
