CWE-511: Logic/Time Bomb

 
Logic/Time Bomb
Weakness ID: 511 (Weakness Base)Status: Incomplete
+ Description

Description Summary

The software contains code that is designed to disrupt the legitimate operation of the software (or its environment) when a certain time passes, or when a certain logical condition is met.

Extended Description

When the time bomb or logic bomb is detonated, it may perform a denial of service such as crashing the system, deleting critical data, or degrading system response time. This bomb might be placed within either a replicating or non-replicating Trojan horse.

Technical Impact: Varies by context; Alter execution logic

+ Demonstrative Examples

Example 1

Typical examples of triggers include system date or time mechanisms, random number generators, and counters that wait for an opportunity to launch their payload. When triggered, a time-bomb may deny service by crashing the system, deleting files, or degrading system response-time.

+ Potential Mitigations

Always verify the integrity of the software that is being installed.

Phase: Implementation

Conduct a code coverage analysis using live testing, then closely inspect the code that is not covered.
