CVE-2026-7053: Buffer Overflow in Tenda F456
CVE-2026-7053 is a high-severity buffer overflow vulnerability in Tenda F456 version 1. 0. 0. 5. It affects the function frmL7ProtForm in the /goform/L7Prot component of the httpd service. The vulnerability 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 is no confirmed patch or official remediation available at this time.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the frmL7ProtForm function of the /goform/L7Prot component within the httpd service on Tenda F456 firmware version 1.0.0.5. An attacker can remotely exploit this flaw by manipulating the 'page' argument, leading to 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 required, and no user interaction needed. The vulnerability has been publicly disclosed with an exploit available, but no official fix or patch has been identified.
Potential Impact
Successful exploitation of this vulnerability can lead to a buffer overflow, which may allow remote attackers to execute arbitrary code or cause denial of service on affected devices. Given the high CVSS score and remote exploitability without privileges or user interaction, impacted devices are at significant risk. However, there is no indication that exploits are currently observed in the wild.
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 the affected device and monitor for any updates from Tenda regarding patches or mitigations. No vendor advisory or official remediation information is currently available.
