AI Analysis
Technical Summary
The Tenda 4G06 router firmware version 04.06.01.29 contains a stack-based buffer overflow vulnerability in the fromDhcpListClient function of the /goform/DhcpListClient endpoint. Remote attackers can manipulate the 'page' argument to trigger the overflow, potentially leading to arbitrary code execution or denial of service. The vulnerability has a CVSS 4.0 score of 8.7, indicating high severity with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No patch or official fix has been documented, and the product is not a cloud service, so remediation depends on vendor updates.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to execute arbitrary code or cause a denial of service on affected Tenda 4G06 devices. The high CVSS score reflects significant impact on confidentiality, integrity, and availability. However, there are no confirmed reports of active exploitation in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or fix is documented, users should monitor Tenda's official channels for updates. Until a fix is available, restricting remote access to the affected endpoint and limiting exposure of the device to untrusted networks may reduce risk.
