A SQL injection vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow remote attackers to inject malicious code. We have already fixed the vulnerability in the following version: SMB Service 4.15.002 and later SMB Service h4.15.002 and later
Solution:
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
