Incorrect access control in the getStaticDhcpRules function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain WPS runtime status 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 WPS runtime status to any attacker on the adjacent network. The getStaticDhcpRules CGI handler at /cgi-bin/cstecgi.cgi fails to enforce access control, allowing a crafted POST request to retrieve WPS operational state without credentials. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be on the same LAN or Wi-Fi segment as the TOTOLINK T6 router (AV:A - adjacent network, not internet-routable). … 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 (4.3 Medium) correctly scopes this as an adjacent-network issue - exploitation requires the attacker to be on the same LAN or Wi-Fi segment as the router, which materially limits exposure compared to internet-facing vulnerabilities. … 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 has been identified at time of analysis; the references point to the TOTOLINK firmware download page and researcher coordination repositories but do not confirm a fixed firmware version. … Detailed patch versions, workarounds, and compensating controls in full report. |
