AI Analysis
Technical Summary
This vulnerability exists in Tenda F451 version 1.0.0.7 within the fromSafeMacFilter function of the httpd component. By sending a specially crafted request manipulating the page/menufacturer argument, an attacker can trigger a stack-based buffer overflow. This flaw allows remote code execution potential due to the high impact on confidentiality, integrity, and availability as indicated by the CVSS vector. The vulnerability is remotely exploitable without privileges or user interaction. No official fix or patch has been confirmed as of the published date.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary code on the affected device, potentially leading to full compromise of the router. This could impact the confidentiality, integrity, and availability of the device and the network it serves. The CVSS score of 8.7 reflects a high severity with significant impact on security properties.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider limiting remote access to the device's management interface and monitor for unusual activity. Avoid exposing the device's management interface to untrusted networks. Follow vendor channels closely for updates or patches.
