A vulnerability in the web-based management interface of Cisco Prime Infrastructure (PI) and Evolved Programmable Network Manager (EPNM) could allow an unauthenticated, remote attacker to conduct a Document Object Model (DOM) based (environment or client-side) cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information. Additional information about DOM-based XSS attacks and potential mitigations can be found at: https://www.owasp.org/index.php/DOM_Based_XSS https://www.owasp.org/index.php/Types_of_Cross-Site_Scripting#DOM_Based_XSS_.28AKA_Type-0.29 There are no workarounds that address this vulnerability.
