CVE-2022-27934Network attack vector

Unauthenticated service interruption via malformed HTTP input

Published Jul 17, 2022 · Updated Aug 3, 2024

Insufficient input validation in Pexip Infinity 25.0 through 27.2 allows remote attackers to trigger a software abort via HTTP. The Hypertext Transfer Protocol implementation accepts malformed input without sufficient validation and aborts the affected process. No authentication or user interaction is required, and the abort interrupts service without reported confidentiality or integrity impact.
