What is CVE-2021-34784?
CVE-2021-34784 is a medium-severity cross-site scripting vulnerability in Cisco Evolved Programmable Network Manager, published on 4 Nov 2021. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
A vulnerability in the web-based management interface of Cisco Prime Infrastructure (PI) and Cisco Evolved Programmable Network Manager (EPNM) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. 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.
Weakness: CWE-79
