CWE-1080: Source Code File with Excessive Number of Lines of Code
A source code file has too many lines of code.
Last updated
Overview
While the interpretation of "too many lines of code" may vary for each product or developer, CISQ recommends a default threshold value of 1000.
Common consequences
What can happen when CWE-1080 is exploited.
Reduce Maintainability, Increase Analytical Complexity
Affects: Other
This issue makes it more difficult to understand and/or maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.
How it happens
When it is introduced
Typically introduced during these phases of the software lifecycle.
How to detect it
Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
Effectiveness: High
