CWE-421: Race Condition During Access to Alternate Channel
The product opens an alternate channel to communicate with an authorized user, but the channel is accessible to other actors.
How it's found
Race Condition During Access to Alternate Channel is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
This creates a race condition that allows an attacker to access the channel before the authorized user does.
Consequences
- Gain Privileges or Assume Identity, Bypass Protection Mechanism
Where this fits in a TurboPentest engagement
