Technical Analysis

This vulnerability arises from improper access control in the setParentalRules function of TOTOLINK T6 firmware 4.1.5cu.748_B20211015. An attacker can exploit this by sending a specially crafted POST request to the /cgi-bin/cstecgi.cgi endpoint, enabling alteration of parental control configurations without authentication. The CVSS v3.1 score is 9.1, indicating high impact on confidentiality and integrity with no required privileges or user interaction.

Potential Impact

Successful exploitation allows unauthenticated attackers to change parental control settings on the affected device, potentially bypassing intended restrictions and compromising device security. The vulnerability impacts confidentiality and integrity but does not affect availability.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the device management interface to trusted users only and monitor for suspicious POST requests targeting /cgi-bin/cstecgi.cgi.
