Vulnerabilities

An attacker can bypass the sandboxing of Nasal scripts and arbitrarily write to any file path that the user has permission to modify at the operating-system level.

In FlightGear before version 2017.3.1, Main/logger.cxx in the FGLogger subsystem allows one to overwrite any file via a resource that affects the contents of the global Property Tree.

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.

The route manager in FlightGear before 2016.4.4 allows remote attackers to write to arbitrary files via a crafted Nasal script.
