CVE-2021-25163Network attack vector

Authenticated file disclosure and resource exhaustion via XXE

Published Apr 29, 2021 · Updated Aug 3, 2024

XXE in Aruba AirWave Management Platform before 8.2.12.1 allows remote authenticated users to read local files or exhaust resources. The web-based management interface accepts XML with insufficient restrictions on external entities, allowing resolution against local files or resource-heavy URIs. A valid account is required; exploitation discloses server files or consumes enough resources to cause a denial-of-service condition.
