CVE-2023-4760Public exploitNetwork attack vector

Authenticated code execution via mixed-separator upload filename

Published Sep 21, 2023 · Updated Sep 24, 2024

Path traversal in Eclipse RAP 3.0.0 through 3.25.0 allows remote authenticated users to execute code via FileUpload on Windows. FileUploadProcessor.stripFileName removes text before a forward slash but retains later backslashes, preserving a relative path in an uploaded filename. The application must expose the FileUpload service on a Windows servlet container, where a crafted WAR filename can escape into Tomcat's executable webapps directory.
