CVE-2024-53677Known exploitationPublic exploitNetwork attack vector

Remote code execution via upload path traversal

Published Dec 11, 2024 · Updated Jan 3, 2025

Path traversal in Apache Struts 2.0.0 through 6.3.0.2 allows remote attackers to upload files outside the intended directory. The legacy FileUploadInterceptor mixes uploaded-file setters with normal parameter setters, so a crafted filename parameter can redirect the accepted upload path after checks. Only applications using this interceptor are exposed; a writable web-served path can turn the unrestricted upload into remote code execution.
