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)

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)
