CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2025-60694 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Linksys E1200 Firmware. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 36% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A stack-based buffer overflow vulnerability exists in the validate_static_route function of the httpd binary on Linksys E1200 v2 routers running firmware E1200_v2.0.11.001_us.tar.gz. The flaw stems from unsafe concatenation of unauthenticated CGI parameters (route_ipaddr_0~3, route_netmask_0~3, and route_gateway_0~3) into fixed-size stack buffers without bounds checking, corresponding to CWE-121. The issue received a CVSS 3.1 score of 7.5 with network attack vector and no required privileges or user interaction.
Remote attackers can exploit the vulnerability by sending specially crafted HTTP requests to the router's web interface, enabling arbitrary code execution or denial of service without authentication. The affected component is exposed to the network, making the flaw remotely triggerable against any internet-facing or LAN-accessible E1200 v2 device.
The listed references point to Linksys vendor pages and a GitHub technical write-up but contain no details on patches, firmware updates, or mitigation steps. The EPSS score reached a modest peak of 0.0513 several months after disclosure before receding to its current value of 0.0318, indicating limited sustained exploitation interest.

Vulnerability Data
A stack-based buffer overflow exists in the validate_static_route function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The function improperly concatenates user-supplied CGI parameters (route_ipaddr_0~3, route_netmask_0~3, route_gateway_0~3) into fixed-size buffers (v6, v10, v14) without proper bounds checking.…
