DescriptionHuatian Dynamic OA8000 collaborative office system contains an unauthenticated path traversal vulnerability in /OAapp/jsp/trace/ntkodownload.jsp, where the filename request parameter is used to locate a file without restricting access to an intended directory or rejecting traversal sequences. Attackers can supply ../ sequences to read arbitrary files from the server, such as the Tomcat configuration at ROOT/WEB-INF/web.xml, exposing sensitive configuration, source, and credential material that can enable further compromise. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-11-20.
