CVE-2024-38886

Data manipulation via unauthenticated TCP packet injection

Published Aug 2, 2024 · Updated Jul 5, 2026

Traffic injection in Horizon Cloud Caterease 16.0.1.1663 through 24.0.1.2405 allows remote attackers to alter client-server data. The client treats unauthenticated TCP packets as trusted traffic because communications with SQL/Application servers lack encryption or source verification. Remote attackers on the same network can read or modify in-transit data, hijack sessions, or interrupt service.
