CVE-2022-48074

Command execution via crafted connection-file parameters

Published Feb 3, 2023 · Updated Aug 3, 2024

Command execution in NoMachine Client before 8.2.3 allows attackers to run commands by inducing a user to open a crafted .nxs file. The client accepts editable command-related parameters from the connection file and launches the configured command without preventing unexpected execution. Opening the file is required, and commands run only with the privileges of the user launching the connection, without privilege escalation.
