Technical Analysis
This vulnerability involves improper access control in the getMeshNeighborTable function of TOTOLINK T6 firmware 4.1.5cu.748_B20211015. An unauthenticated attacker can send a specially crafted POST request to the /cgi-bin/cstecgi.cgi endpoint to obtain mesh neighbor information, which should normally be restricted. The CVSS 3.1 vector indicates the attack requires adjacent network access, has low attack complexity, no privileges required, no user interaction, and results in limited confidentiality impact without affecting integrity or availability.
Potential Impact
An attacker with access to the adjacent network can obtain mesh neighbor information from the affected device without authentication. This may disclose network topology or device details that could aid further attacks. There is no direct impact on integrity or availability reported.
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 the device's management interfaces to trusted users only.
