CVE-2024-20394

Service interruption via malformed local HTTP request

Published May 15, 2024 · Updated Aug 9, 2024

Denial of service in Cisco AppDynamics Network Visibility Agent 24.3.0 and earlier allows local users to stop the service via HTTP requests. The targeted HTTP service does not handle unexpected request input and stops the Network Agent Service instead of rejecting the request. Local device access and user interaction are required; impact is limited to interruption of network-visibility monitoring on that host.
