Incorrect access control in the setScheduleCfg function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to configure forced reboot tasks via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Unauthenticated configuration tampering in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers abuse the setScheduleCfg handler on /cgi-bin/cstecgi.cgi to schedule forced reboot tasks without any credentials. Because the endpoint fails to enforce access control (CWE-284), a single crafted POST can register recurring reboots that render the device persistently unavailable, and the same missing check likely exposes other schedule/config parameters. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be able to send an HTTP POST to the /cgi-bin/cstecgi.cgi endpoint invoking the setScheduleCfg function on a TOTOLINK T6 running firmware 4.1.5cu.748_B20211015; per CVSS PR:N/UI:N no authentication, credentials, or user interaction are required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N, base 9.8) reflects a genuinely low-barrier attack: network-reachable, no authentication, no user interaction. … 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 fixed firmware version is identified in the provided data, so no exact patch version can be cited - check the TOTOLINK download portal (https://www.totolink.net/home/menu/detail/menu_listtpl/download/id/190/ids/36.html) for a build newer than 4.1.5cu.748_B20211015 and apply it once released. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, isolate any TOTOLINK T6 routers from untrusted networks and disable remote administrative access via firewall rules; simultaneously verify your firmware version against 4.1.5cu.748_B20211015 and document affected devices. …
