The Cisco Application Extension Platform contains a privilege escalation vulnerability in the tech support diagnostic shell that may allow an authenticated user to obtain administrative access to a vulnerable Cisco Application Extension Platform module. Cisco has released free software updates that address this vulnerability.
The Cisco Application Extension Platform (AXP) allows third-party applications to be hosted on Cisco Integrated Services Routers (ISR). A privilege escalation vulnerability exists in command-line interface of the the tech support diagnostic shell that may allow an authenticated user to obtain complete administrative access to vulnerable Cisco AXP module. The tech support shell is accessed using the techsupport support shell command.
Authenticated Cisco AXP users can use an application programming interface (API) to execute commands on the Cisco ISR that is hosting the AXP module. It may be possible for an AXP user to obtain sensitive configuration information that allows the user to gain access to the ISR device. Cisco AXP version 1.5 requires that a user be configured in the ISR configuration before the AXP user can execute commands using the API.
Patch Availability:
When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance.
