CVE-2023-27603Network attack vector

Remote code execution via unchecked archive paths

Published Apr 10, 2023 · Updated Oct 22, 2024

Path traversal in Apache Linkis 1.3.1 and earlier allows remote attackers to execute code through a crafted engineConn material ZIP. The Manager module's FsRestfulApi material-upload path extracts archive entries without validating relative paths, allowing entries to escape the intended directory. The network-exposed upload requires no privileges or user interaction, and successful traversal writes attacker-controlled material where the Linkis process can access it.
