Summary
A vulnerability in the web-based management interface of Cisco IoT Field Network Director could allow an authenticated, remote attacker with low privileges to access files and execute commands on a remote router.
This vulnerability is due to insufficient input validation of user-supplied data. An attacker could exploit this vulnerability by submitting crafted input in the web-based management interface. A successful exploit could allow the attacker to create, read, or delete files and execute limited commands in user EXEC mode on a remote router.
