Multiple stack-based buffer overflow vulnerabilities have been identified in the formPingCmd functionality of Planet WGR-500 version 1.3411b190912. These vulnerabilities arise from improper handling of the 'submit-url' and 'ipaddr' HTTP request parameters. An attacker with low privileges can send a specially crafted series of HTTP requests to trigger these overflows, potentially leading to complete compromise of confidentiality, integrity, and availability of the affected device.
