cisco-sa-ios-iot-vds-cred-uPMp9zbY: Cisco IOS Software for Cisco Industrial Routers Virtual Device Server Static Credentials Vulnerability
First published: Wed Jun 03 2020(Updated: )
A vulnerability in the virtual console authentication of Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an authenticated but low-privileged, local attacker to log in to the Virtual Device Server (VDS) of an affected device by using a set of default credentials. The vulnerability is due to the presence of weak, hard-coded credentials. An attacker could exploit this vulnerability by authenticating to the targeted device and then connecting to VDS through the device’s virtual console by using the static credentials. A successful exploit could allow the attacker to access the Linux shell of VDS as the root user. Cisco has released software updates that address this vulnerability. There is a workaround that addresses this vulnerability in Cisco IOS Software releases 15.6(3)M and later. This advisory is available at the following link:https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-iot-vds-cred-uPMp9zbY This advisory is part of the June 3, 2020, release of the Cisco IOS and IOS XE Software Security Advisory Bundled Publication, which includes 23 Cisco Security Advisories that describe 25 vulnerabilities.
