CVE-2020-20913Public exploitNetwork attack vector

Arbitrary code execution via unfiltered search parameter

Published Apr 4, 2023 · Updated Feb 14, 2025

SQL injection in Ming-Soft MCMS 4.7.2 allows remote attackers to execute arbitrary code through a crafted basic_title search parameter. The /cms/{searchId}/search.do handler accepts the POST parameter without filtering, allowing its value to alter a MySQL WHERE or HAVING clause. No authentication or user interaction is required, and successful exploitation can compromise database data and execute code in the server context.
