A buffer copy without checking size of input vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow authenticated administrators to execute code via a network. We have already fixed the vulnerability in the following versions: QTS 5.1.2.2533 build 20230926 and later QuTS hero h5.1.2.2534 build 20230927 and later QuTScloud c5.1.5.2651 and later

A heap-based buffer overflow vulnerability has been reported to affect several QNAP operating system versions.

Buffer Overflow vulnerability in NAS devices. QTS allows attackers to run arbitrary code. This issue affects: QNAP Systems Inc. QTS version 4.2.6 and prior versions on build 20180711; version 4.3.3 and prior versions on build 20180725; version 4.3.4 and prior versions on build 20180710.

CWE-120: Buffer Copy without Checking Size of Input (‘Classic Buffer Overflow’) vulnerability exists that could allow a user with access to the device’s web interface to cause a fault on the device when sending a malformed HTTP request.

A heap-based buffer overflow vulnerability in the processing of Link Control Protocol messages in FortiGate versions 5.6.12, 6.0.10, 6.2.4 and 6.4.1 and earlier may allow a remote attacker with valid SSL VPN credentials to crash the SSL VPN daemon by sending a large LCP packet, when tunnel mode is enabled. Arbitrary code execution may be theoretically possible, albeit practically very difficult to achieve in this context
