Description
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.
Modes of Introduction:
– Implementation
Related Weaknesses
Consequences
Availability: DoS: Crash, Exit, or Restart
An attacker that can trigger an assert statement can still lead to a denial of service if the relevant code can be triggered by an attacker, and if the scope of the assert() extends beyond the attacker’s own session.
Potential Mitigations
Phase: Implementation
Description:
Make sensitive open/close operation non reachable by directly user-controlled data (e.g. open/close resources)
Phase: Implementation
Description:
Perform input validation on user data.
