VNX Control Station for VNX1 and VNX2 contains fixes for multiple security
vulnerabilities that may potentially be exploited by malicious users to
compromise the affected system.
Remote code execution vulnerability (CVE-2017-4984)
An unauthenticated remote attacker may be able to elevate their permissions to
root through a command injection. This may potentially be exploited by an
attacker to run arbitrary code with root-level privileges on the targeted VNX
Control Station system.
CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
Local privilege escalation vulnerability (CVE-2017-4985)
A local authenticated user may potentially escalate their privileges to root
due to authorization checks not being performed on certain perl scripts. This
may potentially be exploited by an attacker to run arbitrary commands as root
on the targeted VNX Control Station system.
CVSS v3 Base Score: 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
Uncontrolled search path vulnerability (CVE-2017-4987)
This vulnerability may be exploited by a local authenticated user to load a
maliciously crafted file in the search path which may potentially allow the
attacker to execute arbitrary code on the targeted VNX Control Station system.
CVSS v3 Base Score: 7.0 (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)
