Technical Analysis
This vulnerability involves incorrect access control in the getWiFiIpMacTable function of TOTOLINK T6 firmware 4.1.5cu.748_B20211015. An attacker without authentication can exploit this flaw by sending a specially crafted POST request to the /cgi-bin/cstecgi.cgi CGI endpoint, which results in disclosure of Wi-Fi client MAC-to-IP address mappings. This information disclosure could aid further network reconnaissance but does not allow modification or disruption of service.
Potential Impact
The impact is limited to confidentiality as attackers can obtain Wi-Fi client MAC-to-IP mappings without authentication. There is no impact on integrity or availability. This information disclosure could facilitate further targeted attacks or network mapping by adversaries.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restricting access to the affected endpoint or network segmentation may reduce exposure.
