Technical details
An allocation of resources without limits or throttling vulnerability (CWE-770) exists in QNAP File Station 6. The flaw allows a remote attacker with valid user credentials to exhaust system resources, such as memory or CPU, by making specific requests that are not properly throttled. Successful exploitation can lead to a denial-of-service (DoS) condition, preventing other applications or processes from accessing the same resource types. The issue is addressed in File Station 5 version 5.5.6.5243 and later.
