Design/Logic Flaw

An issue was discovered on Fujitsu ETERNUS CentricStor CS8000 (Control Center) devices before 8.1A SP02 P04. The vulnerability resides in the grel_finfo function in grel.php. An attacker is able to influence the username (user), password (pw), and file-name (file) parameters and inject special characters such as semicolons, backticks, or command-substitution sequences in order to force the application to execute arbitrary commands.
