Technical Analysis
The vulnerability arises from incorrect access control in the getWiFiEasyCfg function of TOTOLINK T6 firmware 4.1.5cu.748_B20211015. An attacker can exploit this flaw by sending a specially crafted POST request to the /cgi-bin/cstecgi.cgi endpoint, which allows them to obtain sensitive Wi-Fi configuration details including SSIDs and Wi-Fi keys without authentication. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and high confidentiality impact with no integrity or availability impact.
Potential Impact
Successful exploitation results in unauthorized disclosure of sensitive Wi-Fi configuration data, including SSIDs and Wi-Fi keys. This compromises the confidentiality of the wireless network credentials, potentially allowing attackers to access the network. There is no indication of impact on integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Until a patch is available, restrict network access to the device and monitor for suspicious POST requests to /cgi-bin/cstecgi.cgi.
