CVE-2024-20369 [Medium] | Input Validation Bypass in Network Services Orchestrator

A vulnerability in the web-based management interface of Cisco Crosswork Network Services Orchestrator (NSO) could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. This vulnerability is due to improper input validation of a parameter in an HTTP request. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to redirect a user to a malicious website.
