No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A vulnerability in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to perform path traversal attacks on the underlying operating system to either read or delete arbitrary files. To exploit this vulnerability, the attacker must have valid administrative credentials.  This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected system. A successful exploit could allow the attacker to access sensitive files or delete arbitrary files on the affected system.
