CVE-2016-4338 — Zabbix Zabbix security vulnerability

High CVSS 8.1

The mysql user parameter configuration script (userparameter_mysql.conf) in the agent in Zabbix before 2.0.18, 2.2.x before 2.2.13, and 3.0.x before 3.0.3, when used with a shell other than bash, allows context-dependent attackers to execute arbitrary code or SQL commands via the mysql.size parameter.

SQL and data-query injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace request, message, file, and stored values into SQL, ORM query fragments, filters, sort expressions, and other data-query languages.
  • Inventory database roles, reachable schemas, multi-tenant boundaries, and whether stacked or administrative operations are enabled.
  • Check both direct queries and second-order use of previously stored values.

Remediate safely

  • Use parameterized queries or safe query builders for all values; map identifiers and operators through explicit allowlists.
  • Remove raw query concatenation and give the application account only the tables and operations it requires.
  • Update affected data-access components and add regression tests for query structure preservation with inert edge-case inputs.
