Remote code execution via unchecked array index
Published Mar 30, 2020 · Updated Aug 5, 2024
Out-of-bounds write in X-Plane before 11.41 allows remote attackers to execute code or crash the simulator via crafted UDP packets. The ACFN network command uses the attacker-controlled acfn_p parameter as an array index without checking its range, enabling a controlled write outside the array. The interface is enabled by default on UDP port 49000, so exploitation requires only network reachability and no authentication or user interaction.
