DescriptionCVE.org

Incorrect access control in the getWiFiScheduleCfg function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain Wi-Fi scheduling rules via sending a crafted POST request to /cgi-bin/cstecgi.cgi.

AnalysisAI

Unauthenticated disclosure of Wi-Fi scheduling rules in TOTOLINK T6 firmware 4.1.5cu.748_B20211015 allows any adjacent-network attacker to read the router's getWiFiScheduleCfg configuration by sending a crafted POST request to /cgi-bin/cstecgi.cgi without credentials. The CGI handler performs no access control check before returning scheduling policy data. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires adjacent-network access - the attacker must be on the same LAN segment or Wi-Fi broadcast domain as the TOTOLINK T6 management interface (AV:A per CVSS). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	Real-world risk is low despite the unauthenticated access vector. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation	No vendor-released patch or updated firmware version has been identified in the available references at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
