{"id":"CVE-2017-8921","details":"In FlightGear before 2017.2.1, the FGCommand interface allows overwriting any file the user has write access to, but not with arbitrary data: only with the contents of a FlightGear flightplan (XML). A resource such as a malicious third-party aircraft could exploit this to damage files belonging to the user. Both this issue and CVE-2016-9956 are directory traversal vulnerabilities in Autopilot/route_mgr.cxx - this one exists because of an incomplete fix for CVE-2016-9956.","modified":"2026-03-14T09:25:12.577286Z","published":"2017-05-12T19:29:00.300Z","references":[{"type":"FIX","url":"https://sourceforge.net/p/flightgear/flightgear/ci/faf872e7f71ca14c567ac7080561fc785d8d2fd0/"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-8921.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"2017.2"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
