CVE-2023-51927Public exploitNetwork attack vector

Unauthenticated SQL execution via forged Authorization digest

Published Jan 20, 2024 · Updated Jul 9, 2026

SQL injection in Yonyou YonBIP 3_23.05 allows remote attackers to execute arbitrary SQL through the runScript web method. AttendScriptController.runScript() sends the script parameter directly to the database, while an Authorization value derived as the MD5 of the key parameter bypasses the interface check. No account is required; the database account's privileges bound the data that can be read, modified, or deleted and any resulting service interruption.
