CVE-2021-1349Network attack vector

Sensitive information disclosure via Cypher query injection

Published Jan 20, 2021 · Updated Nov 12, 2024

Cypher query injection in Cisco Catalyst SD-WAN Manager before 20.3.2 allows remote authenticated users to read sensitive information. The web-based management interface insufficiently validates attacker-controlled values in crafted HTTP requests before incorporating them into Cypher queries. An authenticated management session is required, and the documented consequence is disclosure without data modification or service interruption.
