Incorrect access control in the getPairCfg function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain pairing and mesh-slave configuration via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Information disclosure in the TOTOLINK T6 mesh router (firmware 4.1.5cu.748_B20211015) lets remote unauthenticated attackers read pairing and mesh-slave configuration by sending a crafted POST request to the getPairCfg handler at /cgi-bin/cstecgi.cgi. The missing access-control check exposes mesh topology and pairing secrets that can facilitate deeper network compromise. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the router's HTTP management endpoint /cgi-bin/cstecgi.cgi and the ability to send a POST invoking the getPairCfg function; no authentication, credentials, or user interaction are needed (PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The published CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N = 9.1) indicates trivial network-reachable, unauthenticated exploitation, which is consistent with the description of a single crafted POST. … 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 version is identified in the provided data, so a specific fixed firmware cannot be cited. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all TOTOLINK T6 mesh routers running firmware 4.1.5cu.748_B20211015 and document their network position and connected topology. …
