Description
The vulnerability allows a remote authenticated attacker to conduct a command-line argument injection attack on a targeted system.
The vulnerability exists due to improper handling user-supplied input when Server Message Block (SMB) volumes are mounted on Windows nodes. A remote authenticated attacker can send specially crafted input to a targeted system while setting up an SMB volume mount, conduct a command-line argument injection attack, which the attacker could use to execute arbitrary code or access or modify sensitive information.
