Cisco Adaptive Security Appliance Software SSH Remote Command Injection Vulnerability (cisco-sa-asa-ssh-rce-gRAuPEUF)

critical Nessus Plugin ID 209660

Synopsis

The remote device is missing a vendor-supplied security patch

Description

A vulnerability in the SSH subsystem of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to execute operating system commands as root.

This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by submitting crafted input when executing remote CLI commands over SSH. A successful exploit could allow the attacker to execute commands on the underlying operating system with root-level privileges. An attacker with limited user privileges could use this vulnerability to gain complete control over the system.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
