An improper neutralization of CRLF sequences (CRLF Injection) vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow remote attackers who have gained administrator access to modify application data.
We have already fixed the vulnerability in the following versions: QTS 5.2.3.3006 build 20250108 and later QuTS hero h5.2.3.3006 build 20250108 and later
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.
