New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis
The remote FTP server is affected by a remote code execution vulnerability.
Description
The remote FTP server is affected by a remote code execution vulnerability due to an error in the Bash shell running on the remote host. A remote, unauthenticated attacker can execute arbitrary code on the remote host by sending a specially crafted request via the USER FTP command. The 'mod_exec' module exports the attacker-supplied username as an environment variable, which is then evaluated by Bash as code.
Solution
Apply the referenced patch.
