CVE-2026-10192: Tenda W12 httpd set_local_time_0 stack-based overflow

A vulnerability was identified in Tenda W12 3.0.0.7(4763). The affected element is the function set_local_time_0 of the file /bin/httpd. Such manipulation of the argument Time leads to stack-based buffer overflow. The attack can be launched remotely. The exploit is publicly available and might be used.

Security readout for executives and security teams

Plain-English summary

CVE-2026-10192 affects Tenda W12 firmware 3.0.0.7(4763). A remote attacker with authenticated access may trigger a stack buffer overflow in the device web service using the Time argument. The issue is rated critical, and a public proof-of-concept is referenced, but the bundle does not show confirmed active exploitation.

Executive priority

Treat this as urgent for any deployed Tenda W12 devices because compromise could affect device control and network security. Priority is highest when management interfaces are reachable beyond trusted administrators or credentials are shared, weak, or reused.

Technical view

The reported flaw is a stack-based buffer overflow in /bin/httpd, function set_local_time_0, reached through manipulation of the Time argument. The CVSS v2 vector is AV:N/AC:L/Au:S/C:C/I:C/A:C, indicating network reachability, low complexity, required authentication, and potential full confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to Tenda W12 devices running firmware 3.0.0.7(4763), especially where the management web service is reachable by untrusted or weakly controlled users. The source bundle does not identify other versions or products as affected.

Exploitation context

The bundle states the attack can be launched remotely and that exploit code is publicly available. CVSS marks authentication as required. KEV is false in the provided data, and no cited source confirms active exploitation in the wild.

Researcher notes

Evidence comes mainly from VulDB and CVE metadata. The affected function, parameter, binary path, CWE-119/CWE-121 classification, and CVSS vector are named. Patch status is not documented in the bundle, so remediation should be tied to vendor guidance rather than assumed fixes.

Mitigation direction

  • Identify Tenda W12 devices and confirm firmware version 3.0.0.7(4763).
  • Restrict management web access to trusted administrative networks only.
  • Disable external exposure of the device web interface where possible.
  • Check Tenda support channels for firmware updates or official mitigation guidance.
  • Rotate administrative credentials if unauthorized access is suspected.

Validation and detection

  • Inventory edge and internal networks for Tenda W12 appliances.
  • Verify firmware version through approved administrative channels.
  • Review access logs for unusual authenticated management activity.
  • Confirm management interfaces are not internet-exposed.
  • Monitor vendor and CVE sources for patch or advisory updates.
