CVE-2025-60688: n/a
A stack buffer overflow vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) Router firmware within the cstecgi.cgi binary (setDefResponse function). The binary reads the "IpAddress" parameter from a web request and copies it into a fixed-size stack buffer using strcpy() without any length validation. Maliciously crafted input can overflow the buffer, leading to potential arbitrary code execution or memory corruption, without requiring authentication.

Technical Summary
This vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) router firmware. The cstecgi.cgi binary's setDefResponse function improperly handles the "IpAddress" parameter by copying it into a fixed-size stack buffer using strcpy() without validating input length. This stack buffer overflow (CWE-121) can be triggered remotely without authentication, potentially leading to arbitrary code execution or memory corruption. No patch or remediation information is currently provided.
Potential Impact
Successful exploitation can cause memory corruption or arbitrary code execution on affected routers without requiring authentication. This could allow attackers to compromise the device, potentially affecting confidentiality and availability. However, no known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the router's web interface from untrusted networks to reduce exposure.
