Incorrect access control in the getMeshNeighborTable function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain mesh neighbor information via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Unauthenticated information disclosure in TOTOLINK T6 firmware 4.1.5cu.748_B20211015 exposes mesh neighbor table data to any attacker on the adjacent network. The getMeshNeighborTable function in the /cgi-bin/cstecgi.cgi CGI interface fails to enforce access control, allowing a crafted POST request to retrieve mesh network topology without credentials. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be on the same adjacent network segment (LAN or WiFi) as the TOTOLINK T6 router - AV:A in the CVSS vector confirms this is not remotely exploitable from the internet. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) accurately reflects the constrained threat surface: exploitation is limited to the adjacent network segment (LAN or WiFi), and the confidentiality impact is low - only mesh neighbor topology data is leaked, not credentials, configuration secrets, or code execution primitives. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch with a confirmed fixed version has been identified at time of analysis for this specific function. … Detailed patch versions, workarounds, and compensating controls in full report. |
Threat intelligence, references, and detailed analysis are available after sign-in.
