Detailsinfo

A vulnerability, which was classified as very critical, has been found in EMC VNX1 and VNX2 (the affected version unknown). This issue affects an unknown part. The manipulation with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In EMC VNX2 versions prior to OE for File 8.1.9.211 and VNX1 versions prior to OE for File 7.1.80.8, 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, aka remote code execution.

The bug was discovered 06/16/2017. The weakness was published 06/19/2017 as not defined posting (Bugtraq). The advisory is shared at securityfocus.com. The identification of this vulnerability is CVE-2017-4984 since 12/29/2016. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 12/29/2020).
