AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated stack overflow reachable over the network with low complexity yields full code execution, so AV:N/AC:L/PR:N/UI:N and C:H/I:H/A:H; service reachability is a practical caveat, not a base-metric change.

Buffer Overflow vulnerability in Tenda W20E V16.01.0.6(2782) allows an attacker to execute arbitrary code. This is an incomplete fix for CVE-2025-44867 and CVE-2026-36819
AnalysisAI
Remote code execution in the Tenda W20E router firmware V16.01.0.6(2782) lets unauthenticated network attackers overflow a stack buffer and run arbitrary code on the device. The flaw is explicitly an incomplete fix for the earlier CVE-2025-44867 and CVE-2026-36819, meaning the same code path remains exploitable despite prior patch attempts. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the vulnerable service on a Tenda W20E running firmware V16.01.0.6(2782); no authentication and no user interaction are needed per the CVSS vector (AV:N/AC:L/PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8) describes a trivially reachable, unauthenticated, network-exploitable RCE, which normally warrants top priority. … 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 patched firmware version is identified in the available data, and because this is an incomplete fix for CVE-2025-44867 and CVE-2026-36819, applying only those prior updates is insufficient - treat the device as unpatched until Tenda publishes a build later than V16.01.0.6(2782), and monitor the disclosure repo at https://github.com/H0111mes/Tenda-W20E-Vulnerability-Disclosure and the NVD record at https://nvd.nist.gov/vuln/detail/CVE-2026-67967 for a fixed release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct a network audit to identify all Tenda W20E devices running V16.01.0.6(2782) and immediately isolate them through firewall rules and network segmentation to restrict inbound access. …
