CWE-1176: Inefficient CPU Computation
The product performs CPU computations using algorithms that are not as efficient as they could be for the needs of the developer, i.e., the computations can be optimized further.
How it's found
Inefficient CPU Computation 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.
Consequences
- Reduce Performance, DoS: Resource Consumption (CPU): This issue can make the product perform more slowly, possibly in ways that are noticeable to the users. If an attacker can influence the amount of computation that must be performed, e.g. by triggering worst-case complexity, then this performance problem might introduce a vulnerability.
Where this fits in a TurboPentest engagement
This weakness is not covered by the automated black-box pentest. IntegSec pentesters cover it in a manual engagement.
