Technical details
An argument injection vulnerability exists in NoMachine due to improper neutralization of argument delimiters within the 'nxchmod.sh' script. A local attacker with low-level privileges can exploit this flaw by passing specially crafted arguments to the script, leading to execution of commands with elevated permissions (Privilege Escalation). The vulnerability is reachable locally and does not require user interaction, though it may depend on specific environmental preconditions. The issue is resolved in NoMachine versions 9.5.7 and 8.23.2.
