Weakness (CWE)
CWE-617: Reachable Assertion
The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.
How to prevent it (4 mitigations)
-
Implementation
If the assertion statement is required (e.g., for security or reliability), change the invoking code to avoid the conditions that trigger the assertion.
-
Implementation
Consider changing the assertion to some other less "fatal" error. This might not be easy to implement, since other code may be needed to handle the error.
-
Implementation
Make sensitive open/close operations non-reachable from directly user-controlled data (e.g. open/close resources)
-
Implementation
Perform input validation on user data.
