Description:
Command injection vulnerability is a security hole in a system or application that allows an attacker to execute commands on a remote device or system. This can be due to programming errors, incorrect settings, or failed input validation. Once this vulnerability is exploited, an attacker could gain privileged access to the system and perform malicious actions, such as stealing confidential data, spreading malware, or disrupting system operation. It is important to keep systems and applications updated and properly configured to protect against command injection vulnerabilities.
Vulnerability was found in Caton Live in the Mini_HTTPD 1.27 version through ICMP Package Shipping functionality to an IP, known as Ping.CGI. Because of a lack of sanitization in the Address parameter, you can create a code to receive a target connection by bringing access to Shell.
