QNAP has patched a remote code execution vulnerability affecting the QTS Media Library in all versions prior to QTS 4.2.6 build 20170905 and QTS 4.3.3.0299 build 20170901. This particular vulnerability allows a remote attacker to execute commands on a QNAP NAS using a transcoding service on port 9251. A remote user does not require any privileges to successfully execute an attack.
Unprivileged user can access all functions in the Surveillance Station component in QNAP TS212P devices with firmware 4.2.1 build 20160601. Unprivileged user cannot login at front end but with that unprivileged user SID, all function can access at Surveillance Station.
This command injection vulnerability in QTS allows attackers to run arbitrary commands in the compromised application. QNAP have already fixed the issue in QTS 4.2.6 build 20170517, QTS 4.3.3.0174 build 20170503 and later versions.
QNAP QTS before 4.2.4 Build 20170313 allows local users to obtain sensitive Domain Administrator password information by reading data in an XOR format within the /etc/config/uLinux.conf configuration file.
Cross-site scripting (XSS) vulnerability in File Station in QNAP QTS before 4.2.0 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
The FTP service in QNAP iArtist Lite before 1.4.54, as distributed with QNAP Signage Station before 2.0.1, has hardcoded credentials, which makes it easier for remote attackers to obtain access via a session on TCP port 21.
