GHSA-3893-J6Q6-WHQ8

Vulnerability from github – Published: 2022-01-13 00:01 – Updated: 2022-07-13 00:01

Details

An issue was discovered in CALDERA 2.8.1. When activated, the Human plugin passes the unsanitized name parameter to a python "os.system" function. This allows attackers to use shell metacharacters (e.g., backticks "``" or dollar parenthesis "$()" ) in order to escape the current command and execute arbitrary shell commands.

Severity ?

8.8 (High)
