CWE-1094—Excessive Index Range Scan for a Data Resource

Weakness Name

Excessive Index Range Scan for a Data Resource

Description

The product contains an index range scan for a large data table, but the scan can cover a large number of rows.

While the interpretation of "large data table" and "excessive index range" may vary for each product or developer, CISQ recommends a threshold of 1000000 table rows and a threshold of 10 for the index range.

Common Consequences

Scope:

Other

Impact:

Reduce Performance

Notes:

This issue can make the product perform more slowly. If the relevant code is reachable by an attacker, then this performance problem might introduce a vulnerability.
