Softbiz Web Host Directory Script is prone to multiple SQL injection vulnerabilities. These issues occur because the application fails to properly sanitize user-supplied input before using it in an SQL query.

Successful exploitation could result in a compromise of the application, disclosure or modification of data, or may permit an attacker to exploit vulnerabilities in the underlying database implementation.

Version 1.1 and earlier are affected; other versions may also be affected.
