CVE-2025-7081
Published: 06 July 2025
Summary
CVE-2025-7081 is a low-severity Command Injection (CWE-77) vulnerability in Belkin F9K1122 Firmware. Its CVSS base score is 2.1 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 7.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A vulnerability classified as critical has been identified in the Belkin F9K1122 router running firmware version 1.00.33. It resides in the formSetWanStatic function within the /goform/formSetWanStatic endpoint of the webs component, where unsanitized input supplied to the arguments m_wan_ipaddr, m_wan_netmask, m_wan_gateway, m_wan_staticdns1, and m_wan_staticdns2 is passed directly to the operating system, resulting in command injection. The issue is tracked under CWE-77 and CWE-78.
An authenticated remote attacker can supply crafted values to these parameters and execute arbitrary operating-system commands on the device. The CVSS 4.0 vector indicates network attack reachability with low attack complexity and low privileges required, producing limited effects on confidentiality, integrity, and availability of the affected router; a public proof-of-concept has been released.
The vendor was notified prior to disclosure but did not respond or issue a patch. The EPSS score has remained flat at 0.0850 with no material increase observed after publication.
