Summary
CVE-2026-82694 is a missing authentication vulnerability in the Web UI of Tenda AC1206 firmware 15.03.06.23. The flaw resides in the R7WebsSecurityHandler function that handles requests to the /goform/ate endpoint, allowing a remote, unauthenticated attacker to invoke privileged device functionality without providing any credentials. The issue has been rated CRITICAL with a CVSS score of 10.0, and a public exploit is available.
Technical details
- Root cause: the
/goform/ateendpoint, handled by theR7WebsSecurityHandlerfunction in the device’s Web UI, does not enforce authentication before processing requests. - Trigger condition: an attacker sends a crafted HTTP request directly to the
/goform/ateendpoint on the exposed management interface. - Attack vector: network-based, requiring no authentication, user interaction, or local access — the interface only needs to be reachable.
- Impact: unauthenticated remote attackers can invoke the affected function to bypass authentication controls entirely, potentially leading to full compromise of the device’s confidentiality, integrity, and availability.
Affected software
- Tenda AC1206, firmware version 15.03.06.23 (Web UI component)
Severity
- CVSS v3.1 Base Score: 10.0 (CRITICAL)
- CVSS v3.1 Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: check with Tenda for an updated firmware release beyond version 15.03.06.23 that addresses this issue and apply it as soon as it is available; no vendor-confirmed patched version has been published at the time of this writing.
- If no patch is available: remove the device’s Web UI and
/goform/ateendpoint from direct internet exposure, restrict management interface access to trusted internal networks only (e.g., via firewall rules or VPN), and disable remote management if not required. - Monitor for unsolicited or anomalous requests to
/goform/ateon internet-facing Tenda AC1206 devices, and consider replacing end-of-life or unsupported hardware.
