AI Analysis
Technical Summary
This vulnerability in Tenda F456 1.0.0.5 involves a buffer overflow in the fromSafeUrlFilter function within the /goform/SafeUrlFilter endpoint of the httpd component. The flaw is triggered by manipulating the 'page' argument remotely, potentially leading to memory corruption. The CVSS 4.0 base score is 8.7, indicating high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high impacts on confidentiality, integrity, and availability. The vulnerability is publicly disclosed but lacks an official fix or patch at this time.
Potential Impact
Successful exploitation of this buffer overflow vulnerability could allow remote attackers to execute arbitrary code or cause denial of service on the affected device. The high CVSS score reflects significant potential impact on confidentiality, integrity, and availability. However, there are no confirmed reports of active exploitation in the wild.
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 network exposure of the affected device and monitor for suspicious activity related to the /goform/SafeUrlFilter endpoint.
