CVE-2019-18386Network attack vector

Systems management fault via crafted message payloads

Published Jan 7, 2020 · Updated Aug 5, 2024

Improper input validation in ClearPath Forward Libra and ClearPath MCP Software Series allows remote attackers to fault systems via crafted messages. The systems-management communication channel processes specifically crafted message payloads that can trigger a system fault and other unspecified effects. Network reachability to that channel is required; the confirmed consequence includes service interruption, while additional impact is unspecified.
