Summary

CVE-2025-7082 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 Unix Shell (T1059.004); 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 exists in Belkin F9K1122 version 1.00.33 within the webs component. Specifically, the formBSSetSitesurvey function at /goform/formBSSetSitesurvey accepts unsanitized input in the wan_ipaddr, wan_netmask, wan_gateway, and wl_ssid arguments, resulting in operating system command injection. The issue is tracked under CWE-77 and CWE-78.

An attacker with low privileges can exploit the flaw remotely by submitting crafted values to the affected endpoint, enabling execution of arbitrary operating system commands on the device. Public proof-of-concept code has been released that demonstrates control over the listed parameters.

No vendor patch or official advisory is available, as Belkin did not respond to disclosure. The associated EPSS score remains flat at 0.0850 with no material increase after publication, and references consist of public exploit details hosted on GitHub and VulDB entries.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
