CVE-2022-20741Network attack vector

Cross-site scripting via insufficient input validation

Published Apr 6, 2022 · Updated Nov 6, 2024

Cross-site scripting in Cisco Secure Network Analytics Network Diagrams before 2.1.1 allows remote authenticated users to run scripts. The web-based management interface insufficiently validates user-supplied input embedded in a crafted link before rendering it in the affected interface. Exploitation requires the attacker to persuade another interface user to follow the link, exposing browser-based information or allowing actions in that user's interface context.
