AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the fromDhcpListClient function of the Tenda F456 router firmware 1.0.0.5, specifically within the /goform/DhcpListClient endpoint of the httpd component. The flaw is triggered by manipulating the 'page' argument, which leads to memory corruption. The vulnerability is remotely exploitable without user interaction and requires low attack complexity and privileges. The CVSS 4.0 base score is 8.7, indicating a high severity impact with high confidentiality, integrity, and availability impact metrics. The vulnerability is publicly disclosed but lacks an official fix or patch at this time.
Potential Impact
Successful exploitation can lead to a buffer overflow condition, potentially allowing remote attackers to execute arbitrary code or cause denial of service on the affected device. The vulnerability impacts confidentiality, integrity, and availability of the device. There are no confirmed reports of exploitation in the wild yet.
