CVE-2016-7468 — F5 Big-Ip Local Traffic Manager security vulnerability

Medium CVSS 5.9

An unauthenticated remote attacker may be able to disrupt services on F5 BIG-IP 11.4.1 - 11.5.4 devices with maliciously crafted network traffic. This vulnerability affects virtual servers associated with TCP profiles when the BIG-IP system's tm.tcpprogressive db variable value is set to non-default setting "enabled". The default value for the tm.tcpprogressive db variable is "negotiate". An attacker may be able to disrupt traffic or cause the BIG-IP system to fail over to another device in the device group.

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.
