CVE-2026-44172: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in MariaDB server
MariaDB server is a community developed fork of MySQL server. In versions 3.3.18 and 3.4.8, an application that was taking non-validated user input, escaping it with mysql_real_escape_string() and sending it to the database using text protocol and big5 character set was vulnerable to SQL injections, even though mysql_real_escape_string() was supposed to prevent them. This issue has been patched in versions 3.3.19 and 3.4.9.
AI Analysis
Technical Summary
MariaDB server versions 3.3.18 and 3.4.8 are vulnerable to SQL injection attacks when an application uses mysql_real_escape_string() to escape user input but sends queries using the text protocol with the big5 character set. The escaping function fails to properly neutralize special elements in this context, leading to potential injection. This vulnerability is addressed in versions 3.3.19 and 3.4.9.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary SQL commands on the database, potentially leading to unauthorized data access or modification. The CVSS score of 6.9 (medium severity) reflects the network attack vector with no privileges required and no user interaction needed, but with limited impact on confidentiality.
Mitigation Recommendations
Upgrade MariaDB server to version 3.3.19 or later, or 3.4.9 or later, where this vulnerability has been patched. No other mitigation guidance is provided; patching is the recommended remediation.
