AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network request to cstecgi.cgi (AV:N/AC:L/PR:N/UI:N); primary impact is exposing internal services (C:H), with no demonstrated integrity/availability compromise beyond rule changes, so I set I/A conservatively to N.

Incorrect access control in the setPortForwardRules function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to expose internal services via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Access-control bypass in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote unauthenticated attackers manipulate port-forwarding rules via a crafted POST to /cgi-bin/cstecgi.cgi, exposing internal LAN services to the internet. The setPortForwardRules handler fails to enforce authentication, so anyone able to reach the device's web interface can create NAT/forwarding entries. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the router's HTTP endpoint /cgi-bin/cstecgi.cgi and the ability to send a POST invoking the setPortForwardRules function; 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 | The signals conflict in a way defenders should weigh carefully: CVSS 3.1 is 9.8 with AV:N/AC:L/PR:N/UI:N (network, low complexity, no auth, no interaction), which argues for urgent treatment, yet EPSS is only 0.16% (6th percentile) and there is no KEV listing and no identified public exploit - indicating no evidence of widespread automated exploitation today. … 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 specific vendor-released patched firmware version is identified in the provided data, so treat this as: no vendor-released patch version independently confirmed at time of analysis - check TOTOLINK's download page (https://www.totolink.net/home/menu/detail/menu_listtpl/download/id/190/ids/36.html) for updated T6 firmware superseding 4.1.5cu.748_B20211015 and apply it once available. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all TOTOLINK T6 routers in your network, audit existing port-forwarding rules for unauthorized entries, and immediately restrict web-interface access via firewall ACLs to trusted administrative subnets only. …
