CVE-2022-45802Network attack vector

Arbitrary file write via unchecked JAR upload

Published May 1, 2023 · Updated Oct 21, 2024

Unrestricted file upload in Apache StreamPark before 2.0.0 allows remote attackers to write dangerous files to arbitrary directories. The application JAR upload path accepts attacker-supplied content without mandatory file-type validation and permits the destination directory to be selected. The network-reachable upload workflow is available to any user; a successful upload can place attacker-controlled content in a security-sensitive location.
