CVE-2025-57174
Published: 15 September 2025
Summary
CVE-2025-57174 is a critical-severity Use of Hard-coded Cryptographic Key (CWE-321) vulnerability in Ceragon (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 17.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SC-12 (Cryptographic Key Establishment and Management) and SC-7 (Boundary Protection).
Deeper analysis
CVE-2025-57174 affects Siklu Communications Etherhaul 8010TX and 1200FX devices running firmware versions 7.4.0 through 10.7.3, and possibly earlier releases or other Etherhaul series models that share the same firmware. The flaw resides in the rfpiped service listening on TCP port 555, which relies on static AES encryption keys that are hardcoded in the binary and identical across all devices. This constitutes a failed remediation of the earlier CVE-2017-7318 and is tracked under CWE-321 for use of hard-coded cryptographic keys.
An unauthenticated attacker with network access can exploit the weakness by crafting specially encrypted packets that the service will accept and execute as arbitrary commands, resulting in full control over the affected device. The vulnerability carries a CVSS 3.1 score of 9.8, reflecting that no authentication, user interaction, or special conditions are required for remote code execution.
Vendor sites for Ceragon and Etherhaul are referenced alongside public disclosure reporting the issue, though no specific patch or mitigation guidance is detailed in the available references. The associated EPSS scores remain low, with a current value of 0.0169 and a peak of 0.0204.
