Description
A vulnerability in the web-based management interface of Cisco Evolved Programmable Network Manager (EPNM) could allow an authenticated, remote attacker with low privileges to access sensitive information that they are not authorized to access. This vulnerability is due to improper authorization checks on a REST API endpoint of an affected device. An attacker could exploit this vulnerability by querying the affected endpoint. A successful exploit could allow the attacker to view session information of active Cisco EPNM users, including users with administrative privileges, which could result in the affected device being compromised.
