Technical Analysis
This vulnerability arises from improper access control in the getWiFiMeshConfig function of TOTOLINK T6 4.1.5cu.748_B20211015. An unauthenticated attacker can exploit this flaw by sending a specially crafted POST request to the /cgi-bin/cstecgi.cgi endpoint, which results in unauthorized disclosure of mesh network configuration and runtime state data. The CVSS 3.1 base score is 7.5, indicating high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impact limited to confidentiality (C:H) without affecting integrity or availability.
Potential Impact
Successful exploitation allows an unauthenticated attacker to obtain sensitive mesh configuration and runtime state information from the affected device. This could potentially aid further attacks or reconnaissance but does not directly impact system integrity or availability.
