What is CVE-2021-42561?

A security flaw in CALDERA 2.8.1 involves the Human plugin that inaccurately handles the 'name' parameter. When activated, it fails to sanitize inputs and directly passes them to a python 'os.system' function. This exposure allows cybercriminals to leverage shell metacharacters, enabling them to escape from the current command and execute arbitrary shell commands. This vulnerability highlights critical oversights in input sanitization and the need for robust security practices.
