Official description
An authenticated RCE vulnerability in the ClearPass Policy Manager web-based management interface allows remote authenticated users to run arbitrary commands on the underlying host. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
