Cisco Catalyst SD-WAN Manager Arbitrary File Overwrite Vulnerability

A vulnerability in the CLI of Cisco Catalyst SD-WAN Manager, formerly Cisco SD-WAN vManage, could allow an authenticated, local attacker to overwrite arbitrary files on the local file system of an affected device. To exploit this vulnerability, the attacker must have valid <em>read-only</em> credentials with CLI access on the affected system.<br><br>
This vulnerability is due to improper access controls on files that are on the local file system. An attacker could exploit this vulnerability by running a series of crafted commands on the local file system of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the affected device and gain privileges of the <em>root </em>user. To exploit this vulnerability, an attacker would need to have CLI access as a low-privilege user.<br><br>

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.<br><br>
