CVE intelligence and bounded remediation

CVE-2018-6393 — FreePBX 10.13.66-32bit and 14.0.1.24 (SNG7-PBX-64bit-1712-2) allow post-authentication SQL injection via the order parameter

High CVSS 7.2

FreePBX 10.13.66-32bit and 14.0.1.24 (SNG7-PBX-64bit-1712-2) allow post-authentication SQL injection via the order parameter. NOTE: the vendor disputes this issue because it is intentional that a user can "directly modify SQL tables ... [or] run shell scripts ... once ... logged in to the administration interface; there is no need to try to find input validation errors.

Matched remediation archetype

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.
