Cisco DNA Center's CronJob scheduler API contains a command injection vulnerability due to improper input validation, allowing authenticated remote attackers to execute arbitrary commands with root privileges.
Vulnerability
The vulnerability resides in the CronJob scheduler API of Cisco Digital Network Architecture (DNA) Center. It is a command injection flaw caused by insufficient validation of user-supplied input. An authenticated, remote attacker can exploit this by sending a specially crafted packet to the affected API. The vulnerability affects Cisco DNA Center software; specific affected versions are detailed in the Cisco Security Advisory [1].
Exploitation
