The administrators of the open-source software Samba have disclosed a vulnerability in their software, which can be used to execute malicious code on affected devices. QNAP® Systems, Inc is committed to protecting the privacy and data security of our users and has released Qfixes for QNAP NAS to patch this vulnerability.

Samba is a network protocol for file and printer sharing. The CVE-2017-7494 remote code execution vulnerability allows clients with write permission to upload a shared library to a shared folder, and then cause the server to load and execute it. By utilizing this exploit, malicious users can run any code on remote servers and obtain administrator privileges. QNAP has provided separate Qfixes for QTS version 4.3.x and 4.2.x. QNAP recommends that users update QTS to the latest version available for their NAS, and then install the Qfix.
