Description
A flaw was found in rubygem-hammer_cli. A command injection vulnerability exists in Hammer CLI and the Railties (Ruby on Rails) component distributed with Satellite due to the insecure interpolation of the $EDITOR environment variable into the Ruby system() method. By passing a single interpolated string to system(), the application invokes a system shell (/bin/sh) that interprets shell metacharacters (e.g., ;, |, &).
