Qnap QTS Bash OS Command Injection (CVE-2014-7169)

critical Tenable OT Security Plugin ID 502562

Synopsis

The remote OT asset is affected by a vulnerability.

Description

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.

This plugin only works with Tenable.ot.
