CVE-2023-4745Public exploitNetwork attack vector

Database disclosure via encoded SQL query execution

Published Sep 3, 2023 · Updated Aug 2, 2024

SQL injection in Byzoro Smart S45F firmware 20230822 allows remote authenticated users to read database data via /importexport.php. The exportexcelbysql path Base64-decodes the sql query parameter and executes the resulting attacker-supplied SELECT statement instead of constraining the export request. Access to the management interface is required; the published reproduction demonstrates database-name and version disclosure, while broader server compromise is asserted but not demonstrated.
