CVE-2020-10803 — Phpmyadmin Phpmyadmin security vulnerability

Medium CVSS 5.4

In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability was discovered where malicious code could be used to trigger an XSS attack through retrieving and displaying results (in tbl_get_field.php and libraries/classes/Display/Results.php). The attacker must be able to insert crafted data into certain database tables, which when retrieved (for instance, through the Browse tab) can trigger the XSS attack.

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.
