Technical Analysis
The vulnerability arises from incorrect access control in the getStaticDhcpRules function of TOTOLINK T6 firmware version 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 CGI endpoint to obtain the WPS runtime status. This issue is identified as CWE-284 (Improper Access Control). No patch or official remediation information is currently available, and there are no known exploits in the wild.
Potential Impact
An attacker without any privileges can access WPS runtime status information, which may aid in further reconnaissance or targeted attacks. The confidentiality impact is limited to information disclosure; integrity and availability are not affected.
Mitigation Recommendations
