CVE-2024-5055Network attack vector

Remote system crash via incomplete HTTP requests

Published May 17, 2024 · Updated Aug 1, 2024

Uncontrolled resource consumption in XAMPP for Windows 7.3.2 and earlier allows remote attackers to crash systems via incomplete HTTP requests. The request-processing path consumes resources without an effective bound while numerous HTTP requests remain unfinished. No authentication or user interaction is required; sustained network input can exhaust availability and crash the Windows host.
