CVE-2025-7092
Published: 06 July 2025
Summary
CVE-2025-7092 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Belkin F9K1122 Firmware. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 21.0% 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 stack-based buffer overflow vulnerability, tracked as CVE-2025-7092, affects the Belkin F9K1122 wireless router running firmware version 1.00.33. The flaw resides in the formWlanSetupWPS function within the /goform/formWlanSetupWPS endpoint of the webs component and is triggered by unsanitized input to the wps_enrolee_pin or webpage arguments, corresponding to CWE-119 and CWE-121.
An authenticated remote attacker can supply a crafted request to overflow the stack buffer, leading to arbitrary code execution with high impact on confidentiality, integrity, and availability. The CVSS 4.0 score of 7.4 reflects network attack vector, low complexity, and low privileges required, and a public proof-of-concept exploit has already been published.
No vendor patch or mitigation guidance has been issued; the manufacturer was notified prior to disclosure but did not respond. The associated EPSS score has remained flat at 0.0116 with no observed increase since publication.

Why these techniques?
Stack-based buffer overflow in the publicly accessible web interface (/goform/formWlanSetupWPS) of the Belkin router enables remote code execution via unauthenticated exploitation, directly facilitating T1190: Exploit Public-Facing Application.

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.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
