Incorrect access control in the getRemoteCfg function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain remote-management enablement and port information via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Unauthenticated remote-management configuration disclosure in TOTOLINK T6 firmware 4.1.5cu.748_B20211015 exposes whether remote administration is enabled and on which port, via a crafted POST to /cgi-bin/cstecgi.cgi invoking the getRemoteCfg function. The root cause is CWE-284 incorrect access control - no authentication check gates the function before returning configuration data. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions are required beyond network reachability of the router's web management interface - the CVSS vector AV:N/AC:L/PR:N/UI:N confirms unauthenticated remote exploitation against the default-enabled HTTP interface on TOTOLINK T6 firmware 4.1.5cu.748_B20211015. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.5 (C:H) reflects unauthenticated network access with no complexity, but the actual confidentiality impact is moderate at best - the function discloses only remote-management enablement status and the listening port, not credentials or session material, which makes C:H a likely overstatement for this specific endpoint. … 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 version has been identified in the available data at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct a network inventory to identify all TOTOLINK T6 devices running firmware version 4.1.5cu.748_B20211015 and document which have internet-facing or remote access capability. …
