CVE-2026-15695: Tenda BE12 Pro DhcpListClient fromDhcpListClient stack-based overflow

A flaw has been found in Tenda BE12 Pro 16.03.66.23. The affected element is the function fromDhcpListClient of the file /goform/DhcpListClient. This manipulation of the argument page causes stack-based buffer overflow. The attack can be initiated remotely. The exploit has been published and may be used.

Security readout for executives and security teams

Plain-English summary

CVE-2026-15695 is a critical buffer overflow reported in Tenda BE12 Pro firmware 16.03.66.23. A remote authenticated user may be able to crash or take control of the device through the DHCP client list function. Public exploit material is referenced, but active exploitation is not confirmed.

Executive priority

Treat this as urgent for affected Tenda BE12 Pro deployments because it is critical, remotely reachable after authentication, and public exploit material is referenced. Prioritize inventory, exposure reduction, and vendor remediation tracking.

Technical view

The flaw is in fromDhcpListClient in /goform/DhcpListClient. Manipulating the page argument can trigger a stack-based buffer overflow. VulDB lists CWE-119 and CWE-121, CVSS 2.0 score 9.0, network attack vector, low complexity, single authentication, and complete confidentiality, integrity, and availability impact.

Likely exposure

Exposure is likely limited to Tenda BE12 Pro devices running firmware 16.03.66.23 where the affected management endpoint is reachable by authenticated users. Risk rises if router administration is exposed to untrusted LAN users or the internet.

Exploitation context

The source bundle says exploit material has been published and may be used. The CVE is not listed as KEV in the bundle, and no cited source confirms active exploitation in the wild.

Researcher notes

Evidence is based on third-party reporting and CVE/VulDB metadata. The bundle identifies the vulnerable function, endpoint, argument, firmware version, and public exploit reference, but does not provide confirmed vendor patch details or confirmed in-the-wild exploitation.

Mitigation direction

  • Identify any Tenda BE12 Pro devices running firmware 16.03.66.23.
  • Check Tenda guidance and firmware availability for a vendor-supported fix.
  • Restrict router management access to trusted administrators and networks.
  • Disable external or untrusted access to management interfaces where possible.
  • Monitor vendor and CVE records for updated remediation details.

Validation and detection

  • Inventory network devices and confirm model and firmware version.
  • Review whether /goform/DhcpListClient is reachable from untrusted networks.
  • Check admin access paths and remove unnecessary exposure.
  • Look for logs or alerts involving unusual DHCP client list requests.
  • Track the referenced CVE and VulDB pages for status changes.
