Summary:  
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.

Details:  

?       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)
