Summary

JeeWMS before commit 0a610e8 contains an unauthenticated path traversal vulnerability that allows remote attackers to read arbitrary files via the dbPath parameter. Attackers can send GET requests to /systemController/showOrDownByurl.do with ../ sequences in dbPath, which bypasses AuthInterceptor, to retrieve files like win.ini. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-17.
