This vulnerability has a CVSS 3.1 base score of 4.4, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
A vulnerability in the restricted shell of Cisco Evolved Programmable Network (EPN) Manager, Cisco Identity Services Engine (ISE), and Cisco Prime Infrastructure could allow an authenticated, local attacker to identify directories and write arbitrary files to the file system. This vulnerability is due to improper validation of parameters that are sent to a CLI command within the restricted shell. An attacker could exploit this vulnerability by logging in to the device and issuing certain CLI commands. A successful exploit could allow the attacker to identify file directories on the affected device and write arbitrary files to the file system on the affected device. To exploit this vulnerability, the attacker must be an authenticated shell user.
Remediation
Check the references section for vendor advisories and patches from cisco. Update evolved_programmable_network_manager to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
