CVE-2023-20131 [Medium] | XSS in Prime Infrastructure

Multiple vulnerabilities in the web-based management interface of Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager (EPNM) could allow a remote attacker to obtain privileged information and conduct cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks. For more information about these vulnerabilities, see the Details section of this advisory.
