タイトルLinksys WRT54G v4.21.5 Command Injection
説明The Linksys WRT54G Firmware v4.21.5 has a stack overflow vulnerability in validate_services_port function. The variable services_array receives the parameter from a POST request. In line 55, the sscanf function parse POST parameter to v22. the v22 variable is stack-allocated and has a size of only 80 characters. If the variable exceeds this length, it can result in a buffer overflow vulnerability, potentially leading to remote code execution or denial-of-service attacks.
