Technical Analysis
This vulnerability arises from incorrect access control in the getWiFiBasicCfg function of TOTOLINK T6 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 sensitive wireless configuration data such as SSIDs and Wi-Fi keys. The CVSS vector indicates the attack requires adjacent network access, has low complexity, no privileges or user interaction, and impacts confidentiality only.
Potential Impact
An unauthenticated attacker with access to the adjacent network can obtain sensitive wireless configuration information, including SSIDs and Wi-Fi keys. This exposure could facilitate unauthorized network access or further attacks relying on knowledge of wireless credentials. 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 workaround is currently documented. Until a patch is available, restrict network access to trusted users and monitor for suspicious activity targeting the affected endpoint.
