CVE-2023-38905Public exploit

Service interruption via duplicate-check SQL injection

Published Aug 17, 2023 · Updated Oct 8, 2024

SQL injection in Jeecg Boot 3.5.0 and earlier allows local users to interrupt service through the duplicate-check endpoint. The /sys/duplicate/check handler accepts a crafted fieldName value that bypasses checksql filtering, letting database delay functions execute. Local authenticated access is required, and successful exploitation delays database processing enough to deny service without disclosed data access or modification.
