AI Analysis
Technical Summary
CVE-2026-7097 is a remotely exploitable buffer overflow vulnerability in the Tenda F456 router firmware version 1.0.0.5. The flaw resides in the fromwebExcptypemanFilter function of the /goform/webExcptypemanFilter endpoint within the httpd component. By manipulating the 'page' argument, an attacker can cause a buffer overflow condition. The vulnerability has a CVSS 4.0 base score of 8.7, indicating high severity, and a public exploit is available. No vendor patch or official remediation has been disclosed.
Potential Impact
Successful exploitation of this vulnerability could allow an unauthenticated remote attacker to cause a buffer overflow, potentially leading to denial of service or arbitrary code execution on the affected device. Given the high CVSS score and public exploit availability, this poses a significant risk to devices running the vulnerable firmware version.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider limiting network exposure of the affected device and monitoring for unusual activity related to the /goform/webExcptypemanFilter endpoint.
