CVE-2021-21465 — The BW Database Interface allows an attacker with low privileges to execute any crafted database queries, exposing the backend database

Critical CVSS 9.9

The BW Database Interface allows an attacker with low privileges to execute any crafted database queries, exposing the backend database. An attacker can include their own SQL commands which the database will execute without properly sanitizing the untrusted data leading to SQL injection vulnerability which can fully compromise the affected SAP system.

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.
