Technical Analysis
The vulnerability in TOTOLINK T6 4.1.5cu.748_B20211015 is due to improper access control in the getWiFiAclRules function. An attacker without authentication can exploit this by crafting a POST request to the /cgi-bin/cstecgi.cgi CGI endpoint to obtain Wi-Fi Access Control List (ACL) rules. This could potentially expose network configuration details to unauthorized parties. There is no information on active exploitation or available patches.
Potential Impact
Unauthenticated attackers can access Wi-Fi ACL rules, potentially revealing sensitive network configuration information. This exposure could aid further attacks or reconnaissance but does not directly indicate remote code execution or denial of service.
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 to /cgi-bin/cstecgi.cgi.
