CVE-2023-4760
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
