What it is

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.
