CVE-2024-43773Network attack vector

Arbitrary SQL execution via unsanitized cstr parameter

Published Sep 2, 2024 · Updated Sep 3, 2024

SQL injection in Easytest Online Test Platform 24E01 and earlier allows remote attackers to execute arbitrary SQL commands via cstr. The download-class learning-course function incorporates the attacker-controlled cstr parameter into a database operation without neutralizing SQL syntax. No authentication or user interaction is required, and successful exploitation gives the attacker direct control over database queries and stored data.
