CVE-2023-4760
Remote Code Execution in Eclipse RAP on Windows
In Eclipse RAP versions from 3.0.0 up to and including 3.25.0, Remote Code Execution is possible on Windows when using the FileUpload component.
The reason for this is a not completely secure extraction of the file name in the FileUploadProcessor.stripFileName(String name) method. As soon as this finds a / in the path, everything before it is removed, but potentially \ (backslashes) coming further back are kept.
For example, a file name such as /....\webapps\shell.war can be used to upload a file to a Tomcat server under Windows, which is then saved as ....\webapps\shell.war in its webapps directory and can then be executed.
