CVE-2026-6122: Stack-based Buffer Overflow in Tenda F451
CVE-2026-6122 is a high-severity stack-based buffer overflow vulnerability in the Tenda F451 router firmware version 1. 0. 0. 7. The flaw exists in the frmL7ProtForm function within the /goform/L7Prot component of the httpd service. This vulnerability can be triggered remotely by manipulating the 'page' argument, potentially leading to memory corruption. Although the exploit has been publicly disclosed, there are no confirmed reports of active exploitation in the wild. No official patch or remediation guidance has been provided by the vendor as of the publication date.
AI Analysis
Technical Summary
The vulnerability CVE-2026-6122 affects Tenda F451 version 1.0.0.7 and is caused by improper handling of the 'page' argument in the frmL7ProtForm function of the /goform/L7Prot endpoint in the httpd component. This leads to a stack-based buffer overflow, which can be exploited remotely without user interaction or privileges. The CVSS 4.0 base score is 8.7, indicating a high impact with network attack vector, low attack complexity, no privileges required, and no user interaction. The vulnerability allows for high confidentiality, integrity, and availability impact. No official fix or patch has been documented in the available data.
Potential Impact
Successful exploitation of this vulnerability may allow a remote attacker to cause a stack-based buffer overflow, potentially leading to arbitrary code execution, denial of service, or system compromise on the affected device. The high CVSS score reflects significant risk to confidentiality, integrity, and availability. However, there are no confirmed reports of 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 available, users should limit exposure of the affected device to untrusted networks and consider disabling or restricting access to the vulnerable httpd service endpoint if possible. Monitor official Tenda communications for updates on patches or mitigations.
