This vulnerability allows remote attackers to execute arbitrary code on affected installations of QNAP NAS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the RTSS server, which listens on TCP port 8899 by default. The issue results from the lack of authentication prior to allowing alterations to the system configuration. An attacker can leverage this vulnerability to execute arbitrary code in the context of the Administrator.

A command injection vulnerability has been reported to affect certain versions of Malware Remover. If exploited, this vulnerability allows remote attackers to execute arbitrary commands. This issue affects: QNAP Systems Inc. Malware Remover versions prior to 4.6.1.0. This issue does not affect: QNAP Systems Inc. Malware Remover 3.x.

This vulnerability allows network-adjacent attackers to create arbitrary files on affected installations of QNAP NAS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the MusicStation application. When parsing the arttype request parameter, the process does not properly validate a user-supplied path prior to using it in file operations.An attacker can leverage this vulnerability to create files in the context of the admin user.

cgi-bin/pingping.cgi on QNAP VioStor NVR devices with firmware 4.0.3, and in the Surveillance Station Pro component in QNAP NAS, allows remote authenticated users to execute arbitrary commands by leveraging guest access and placing shell metacharacters in the query string.

The QNAP TS-239 Pro and TS-639 Pro with firmware 2.1.7 0613, 3.1.0 0627, and 3.1.1 0815 create an undocumented recovery key and store it in the ENCK variable in flash memory, which allows local users to bypass the passphrase requirement and decrypt the hard drive by reading this variable, deobfuscating the key, and running a cryptsetup luksOpen command.

The QNAP TS-239 Pro and TS-639 Pro with firmware 2.1.7 0613, 3.1.0 0627, and 3.1.1 0815 use the rand library function to generate a certain recovery key, which makes it easier for local users to determine this key via a brute-force attack.
