KB-11522: Dzcheck.sample May be Vulnerable to a Shell Variable Substitution Issue in Version 5.4.0 an Later

Authentication Service ,  

1 January,19 at 01:49 AM

Problem:
For CDC 5.4.0 and later, Centrify shipped a dzcheck.sample script for customers intending to use the dzdo dzcheck feature. We have since discovered that the perl logger call may still launch a shell which means it may still be subject to the shell variable substitution attack if not properly implemented.

Solution:
Ensure to follow the installation and configuration documentation exactly as described. If implementation isn't completed properly, this vulnerability can become apparent.

Note: The sample perl script is intended only as an example, not for production use.
