Weaver E-cology 8.0 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files through the fpath parameter of the /weaver/ln.FileDownload endpoint. Attackers can send crafted GET requests with directory traversal sequences in fpath to retrieve sensitive files such as WEB-INF/web.xml from the server.
