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 a LUKS partition by using the AES-256 cipher in plain CBC mode, which allows local users to obtain sensitive information via a watermark attack. El QNAP TS-239 Pro y TS-639 Pro con firmware v2.1.7 0613, v3.1.0 0627, y v3.1.1 0815 crea una partición LUKS empleando el cifrado AES-256 en modo CBC plano, lo que permite a usuarios locales obtener información sensible a través de un ataque "watermark". • http://secunia.com/advisories/36793 http://www.baseline-security.de/downloads/BSC-Qnap_Crypto_Backdoor-CVE-2009-3200.txt http://www.securityfocus.com/archive/1/506607/100/0/threaded • CWE-310: Cryptographic Issues •

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. El QNAP TS-239 Pro y TS-639 Pro con firmware v2.1.7 0613, v3.1.0 0627, y v3.1.1 0815 emplea la función "rand" de la biblioteca para generar ciertos tipos de claves de recuperación, lo que facilita a usuarios locales adivinar esa clave a través de un ataque de fuerza bruta. • http://secunia.com/advisories/36793 http://www.baseline-security.de/downloads/BSC-Qnap_Crypto_Backdoor-CVE-2009-3200.txt http://www.securityfocus.com/archive/1/506607/100/0/threaded http://www.securityfocus.com/bid/36467 • CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) •
CVSS: 5.9EPSS: 0%CPEs: 6EXPL: 1CVE-2009-3200 – QNAP Systems Encryption Bypass
https://notcve.org/view.php?id=CVE-2009-3200
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. QNAP TS-239 Pro y TS-639 Pro con firmware v2.1.7 0613, v3.1.0 0627, y v3.1.1 0815 crea una clave de recuperación no documentada y la almacena en la variable ENCK en memoria flash, permitiendo a usuarios locales saltar el requisito de contraseña y desencriptar el disco duro mediante la lectura de esta variable, desofuscando la clave, y ejecutando un comando cryptsetup luksOpen. QNAP Systems versions TS-239 Pro and TS-639 Pro suffer from a hard disk encryption bypass vulnerability. • http://forum.qnap.com/viewtopic.php?f=11&t=11214&start=20#p63346 http://forum.qnap.com/viewtopic.php?f=12&t=12104&start=10#p63341 http://secunia.com/advisories/36793 http://www.baseline-security.de/downloads/BSC-Qnap_Crypto_Backdoor-CVE-2009-3200.txt http://www.securityfocus.com/archive/1/506607/100/0/threaded http://www.securityfocus.com/bid/36467 http://www.securitytracker.com/id?1022916 https://exchange.xforce.ibmcloud.com/vulnerabilities/53391 • CWE-310: Cryptographic Issues •
