SQL injection via unescaped string query arguments
Published Sep 28, 2021 · Updated Aug 4, 2024
SQL injection in ThinkPHP 3.2.3 and earlier allows remote attackers to execute arbitrary SQL through string input to where or query. The Model methods escape substitution values only when a separate parse array is supplied; otherwise, where stores raw strings and parseSql performs table-token replacement without parameterization. Exposure requires a consuming application to pass attacker-controlled strings into these methods, granting the database permissions held by that application.
