A vulnerability exists in the iox
command in Cisco IOS and IOS XE Software that could allow an authenticated, local attacker to perform command injection into the IOx Linux guest operating system (GOS).
This vulnerability is due to insufficient input validation of iox
command line arguments. An attacker could exploit this vulnerability by providing crafted options to the iox
command. An exploit could allow the attacker to execute commands of their choice in the Linux GOS.
Cisco has not released software updates that address this vulnerability. Workarounds that address this vulnerability are not available.
