CVE-2019-19606Public exploitNetwork attack vector

Remote command execution via unchecked network paths

Published Mar 30, 2020 · Updated Aug 5, 2024

Path traversal in X-Plane before 11.41 allows remote attackers to read or write arbitrary files via crafted UDP packets. The default-enabled UDP interface on port 49000 accepts unfiltered path parameters in its SIMO, ACFN, and OBJN commands. An unauthenticated attacker can escape the installation directory, leak Windows credentials through UNC paths, or place startup content that executes commands after reboot.
