CVE-2017-15965 — The NS Download Shop (aka com_ns_downloadshop) component 2.2.6 for Joomla!

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.
