CVE-2019-1646: Privilege Escalation Vulnerability in Cisco SD-WAN Solution
First published: Wed Jan 23 2019(Updated: )
A vulnerability in the local CLI of the Cisco SD-WAN Solution could allow an authenticated, local attacker to escalate privileges and modify device configuration files. The vulnerability exists because user input is not properly sanitized for certain commands at the CLI. An attacker could exploit this vulnerability by sending crafted commands to the CLI of an affected device. A successful exploit could allow the attacker to establish an interactive session with elevated privileges. The attacker could then use the elevated privileges to further compromise the device or obtain additional configuration data from the device.
