CVE-2024-3742Network attack vector

System access via cleartext credential storage

Published Apr 18, 2024 · Updated Aug 1, 2024

Cleartext credential storage in Electrolink FM, DAB, and TV transmitters allows remote attackers to obtain system access. The transmitters retain credentials without cryptographic protection, but CISA has not identified the storage location or retrieval path. Network reachability and acquisition of the stored credentials are required; the reported consequence is unauthorized access and confidentiality loss.
