Description

This security bulletin contains information about 1 vulnerability.


1) Command-line argument injection attack (CVE-ID: CVE-2018-1002101)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 9.4 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H]


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.
