Incorrect access control in the getDeviceInfo function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain device identification details via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Incorrect access control in the getDeviceInfo endpoint of TOTOLINK T6 firmware 4.1.5cu.748_B20211015 exposes device identification details to unauthenticated adjacent-network attackers via a crafted POST request to /cgi-bin/cstecgi.cgi. The missing authentication check on this CGI function allows any host on the same network segment to enumerate device model, firmware version, and related identification metadata without credentials. …

Vulnerability AssessmentAI
| Exploitation | The attacker must be on the same Layer-2 network segment (LAN or Wi-Fi) as the TOTOLINK T6 device - internet-remote exploitation is not possible given the AV:A vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N scores 4.3 (Medium) and is well-calibrated to the actual impact: the attack vector is Adjacent (LAN-segment only, not internet-routable), confidentiality impact is Low (device identification strings, not credentials or keys), and there is no integrity or availability impact. … 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 patched firmware version has been identified in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Threat intelligence, references, and detailed analysis are available after sign-in.
