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

A vulnerability in the web-based management interface of Cisco Prime Infrastructure (PI) and Cisco Evolved Programmable Network (EPN) Manager could allow an authenticated, remote attacker to execute code with root-level privileges on the underlying operating system. This vulnerability exist because the software improperly validates user-supplied input. An attacker could exploit this vulnerability by uploading a malicious file to the administrative web interface. A successful exploit could allow the attacker to execute code with root-level privileges on the underlying operating system.

Publicly available exploits

(5 references)

Working exploit code is in the public domain (1 Metasploit module) (1 GitHub PoC) (2 Exploit-DB entries). Defenders should treat patch urgency accordingly — public PoCs typically lead to mass-exploitation within 24-72 hours.
