CVE-2023-7039Public exploitNetwork attack vector

Authenticated code execution via SQL outfile write

Published Dec 21, 2023 · Updated Apr 24, 2025

SQL injection in Byzoro S210 20231210 and earlier allows remote authenticated users to execute code through the sql parameter. The /importexport.php handler executes the Base64-decoded sql value as a database statement, permitting SELECT INTO OUTFILE to write PHP beneath the web root. Low-privileged access is sufficient; the published proof of concept writes /usr/hddocs/nsg/app/sec.php and then requests it as a webshell.
