Technical Analysis

The vulnerability CVE-2026-51629 affects TOTOLINK T6 version 4.1.5cu.748_B20211015. Due to improper access control in the getStaticDhcpRules function, unauthenticated attackers can obtain static DHCP reservation rules by sending a specially crafted POST request to the /cgi-bin/cstecgi.cgi endpoint. The CVSS 3.1 base score is 4.3, reflecting low complexity and no privileges required, with impact limited to confidentiality. No official patch or remediation guidance is currently available.

Potential Impact

An attacker can access static DHCP reservation rules without authentication, potentially exposing network configuration details. There is no impact on integrity or availability. This may aid further reconnaissance but does not directly allow system compromise.

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 management interface and monitor for suspicious POST requests targeting /cgi-bin/cstecgi.cgi.
