CVE-2025-20280: Cisco Evolved Programmable Network Manager

Medium severity, CVSS 4.8. EPSS: 0.2% chance of exploitation in the next 30 days.

A vulnerability in the web-based management interface of Cisco Evolved Programmable Network Manager (EPNM) and Cisco Prime Infrastructure could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against users of the interface of an affected system. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious code into specific data fields in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, an attacker must have valid administrative credentials.

Affected products

• Cisco Evolved Programmable Network Manager: up to and including 8.0.0; version 8.1.0 only
• Cisco Prime Infrastructure: up to and including 3.9; from 3.10, up to and including 3.10.6
