Creation of Immutable Text Using String Concatenation
The product creates an immutable text string using string concatenation operations.
Extended Description
When building a string via a looping feature (e.g., a FOR or WHILE loop), the use of += to append to the existing string will result in the creation of a new object with each iteration. This programming pattern can be inefficient in comparison with use of text buffer data elements. This issue can make the product perform more slowly. If the relevant code is reachable by an attacker, then this could be influenced to create performance problem.

Vulnerability Mapping Notes
Rationale : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.Comments : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
