CVE-2026-7053: Buffer Overflow in Tenda F456
CVE-2026-7053 is a high-severity buffer overflow vulnerability in the Tenda F456 router firmware version 1. 0. 0. 5. The flaw exists in the function frmL7ProtForm within the /goform/L7Prot component of the httpd service. It can be triggered remotely by manipulating the 'page' argument, potentially allowing an attacker to cause a buffer overflow. Although an exploit has been publicly released, there are no confirmed reports of exploitation in the wild. No official patch or remediation guidance is currently available from the vendor.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-7053) affects Tenda F456 version 1.0.0.5 and involves a buffer overflow in the frmL7ProtForm function of the /goform/L7Prot endpoint in the httpd component. The issue arises from improper handling of the 'page' argument, enabling remote attackers to overflow a buffer. The CVSS 4.0 base score is 8.7, reflecting high severity with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. The vulnerability is publicly disclosed with an exploit available, but no vendor patch or official remediation has been published yet.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to execute arbitrary code or cause denial of service on affected Tenda F456 devices. The high CVSS score indicates significant potential impact on device 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. Until an official fix is released, users should consider limiting network exposure of affected devices, such as restricting remote access to the management interface. Monitor vendor communications for updates on patches or mitigations.
