Weakness
CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection')
The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs.
How to prevent it
- Implementation: Avoid using CRLF as a special sequence.
- Implementation: Appropriately filter or quote CRLF sequences in user-controlled input.
