Cisco Prime Infrastructure (CPI) is a wired and wireless network management software suite that consists of different networking applications from Cisco Systems. The system is used across various industries, from healthcare, manufacturing, government, IT, etc. A vulnerability was found in the runrshell binary, which would allow a local user to gain control under the context of root. It is also chained by other publicly known CPI remote exploits to get root in one shot, such as CVE-2018-15379 by Pedro Ribeiro, and CVE-2019-1821 by Steven Seeley. As of now, there appears to be no patch from Cisco.

A vulnerability in which the HTTP web server for Cisco Prime Infrastructure (PI) has unrestricted directory permissions could allow an unauthenticated, remote attacker to upload an arbitrary file. This file could allow the attacker to execute commands at the privilege level of the user prime. This user does not have administrative or root privileges. The vulnerability is due to an incorrect permission setting for important system directories. An attacker could exploit this vulnerability by uploading a malicious file by using TFTP, which can be accessed via the web-interface GUI. A successful exploit could allow the attacker to run commands on the targeted application without authentication.
