A vulnerability in the CLI interface of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to read arbitrary files on the underlying file system of an affected system. This vulnerability exists because access to sensitive information on an affected system is not sufficiently controlled. An attacker could exploit this vulnerability by gaining unauthorized access to sensitive information on an affected system. A successful exploit could allow the attacker to create forged authentication requests and gain unauthorized access to the web UI of an affected system. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link:https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-vmanage-infdis-LggOP9sE
