Invokable Control Element with Excessive Volume of Commented-out Code

A function, method, procedure, etc. contains an excessive amount of code that has been commented out within its body.


Description

This issue makes it more difficult to maintain the software, 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.

While the interpretation of "excessive volume" may vary for each product or developer, CISQ recommends a default threshold of 2% of commented code.
