CVE-2017-4985 — Emc Vnx2 Firmware security vulnerability
High
CVSS 7.8
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, 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.

Matched remediation archetype
Authorization bypass, IDOR, and cross-tenant access
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
- Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
- Use synthetic fixtures to compare intended access matrices without accessing another user's real data.
Remediate safely
- Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
- Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
- Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
