CVE-2019-20059 — Mfscripts Yetishare security vulnerability

High CVSS 8.8

payment_manage.ajax.php and various *_manage.ajax.php in MFScripts YetiShare 3.5.2 through 4.5.4 directly insert values from the sSortDir_0 parameter into a SQL string. This allows an attacker to inject their own SQL and manipulate the query, typically extracting data from the database, aka SQL Injection. NOTE: this issue exists because of an incomplete fix for CVE-2019-19732.

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.
