CWE-514: Covert Channel
A covert channel is a path that can be used to transfer information in a way not intended by the system's designers.
How it's found
Covert Channel describes a general pattern rather than a single fixed bug. Testers use a mix of static analysis and manual code review to find where a target's code matches this pattern, then confirm exploitability by hand.
Typically the system has not given authorization for the transmission and has no knowledge of its occurrence.
