A buffer overflow vulnerability in password function in QNAP QTS version 4.2.6 build 20171026, 4.3.3.0378 build 20171117, 4.3.4.0387 (Beta 2) build 20171116 and earlier could allow remote attackers to execute arbitrary code on NAS devices.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
