CVE-2026-7030: Buffer Overflow in Tenda F456
CVE-2026-7030 is a high-severity buffer overflow vulnerability in Tenda F456 version 1. 0. 0. 5. It affects the fromRouteStatic function in the /goform/RouteStatic file, where manipulation of the 'page' argument can cause a buffer overflow. The vulnerability can be exploited remotely without user interaction or privileges. Although the exploit has been publicly disclosed, no known exploits are currently observed in the wild. There is no official patch or remediation guidance available at this time.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the fromRouteStatic function of the Tenda F456 router firmware version 1.0.0.5. The issue arises from improper handling of the 'page' argument in the /goform/RouteStatic endpoint, allowing remote attackers to trigger a buffer overflow condition. The CVSS 4.0 base score is 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 official fix or patch has been published by the vendor, and the vulnerability is not related to cloud services. The exploit code has been publicly disclosed but is not yet observed in active exploitation.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to cause a buffer overflow, potentially leading to arbitrary code execution or denial of service on affected Tenda F456 devices running firmware version 1.0.0.5. The impact affects confidentiality, integrity, and availability of the device. Given the high CVSS score and remote attack vector, affected devices are at significant risk if unmitigated.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or temporary fix is currently available, users should monitor Tenda's official channels for updates. In the meantime, restricting network access to the affected device's management interface and disabling remote management features, if possible, may reduce exposure.
