CVE-2020-21394Public exploitNetwork attack vector

Administrator-authenticated SQL injection via unfiltered table name

Published Jun 29, 2021 · Updated Aug 4, 2024

SQL injection in Zhong Bang Technology CRMEB mall system 2.60 and 3.1 allows remote authenticated users to execute arbitrary SQL. The seetable handler takes tablename directly from the request, concatenates it into native SQL, and passes the result to Db::query without filtering. A valid administrator session cookie is required, and resulting access is limited to the application database account's permissions.
