Technical details
A SQL injection vulnerability exists in YzmCMS up to version 7.5 within the installation component located at /application/install/index.php. The root cause is the improper neutralization of the 'siteurl' POST parameter, which is processed only with trim() before being concatenated into an UPDATE SQL statement and executed via PDO->exec(). Although the attack can be performed remotely without authentication, it is considered high complexity as it typically targets the installation phase. Successful exploitation allows an attacker to execute arbitrary SQL commands, potentially leading to information disclosure or full system compromise. No official patch has been released by the vendor.
