Technical Analysis

This vulnerability involves incorrect access control in the getTelnetCfg function of TOTOLINK T6 firmware 4.1.5cu.748_B20211015. An unauthenticated attacker can send a crafted POST request to /cgi-bin/cstecgi.cgi to obtain information about whether the Telnet service is enabled on the device. The CVSS vector indicates the attack requires adjacent network access, no privileges, and no user interaction, impacting confidentiality with limited scope.

Potential Impact

An attacker can gain information about the Telnet service enablement status on the affected device without authentication. This information disclosure could aid in further targeted attacks but does not directly impact integrity or availability.
