CVE-2023-3435Public exploitNetwork attack vector

Unauthenticated SQL injection via export parameters

Published Aug 14, 2023 · Updated Oct 9, 2024

SQL injection in Solwin Infotech User Activity Log before 1.6.5 allows remote attackers to execute arbitrary SQL via crafted export requests. The export handler inserts the userrole, username, type, txtsearch, or showip query parameter into a SQL statement without adequate sanitization or escaping. No authentication or user interaction is required, and injected time-delay expressions demonstrate control of database query execution.
