Incorrect access control in the getWiFiApcliScan function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to trigger wireless scans and retrieve AP-client scan results via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Unauthenticated information exposure in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers invoke the getWiFiApcliScan handler via /cgi-bin/cstecgi.cgi to force a wireless scan and read back AP-client scan results without any credentials. The flaw is an incorrect access-control (CWE-284) gap: the CGI endpoint does not verify authentication before executing the scan. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the router's HTTP management service and the ability to POST to the /cgi-bin/cstecgi.cgi endpoint with the getWiFiApcliScan function selector; no credentials, tokens, or user interaction are needed (CVSS PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict. … 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 is identified in the available data (the TOTOLINK references point to product/download pages, not a specific fixed build), so this should be treated as No vendor-released patch identified at time of analysis - monitor https://www.totolink.net/ for updated T6 firmware superseding 4.1.5cu.748_B20211015. … Detailed patch versions, workarounds, and compensating controls in full report. |
