Description

Omnispace Agora Project before 26.10.0 contains a code injection vulnerability where unescaped, attacker-controlled values are written into the config.inc.php configuration file during installation through File::updateConfigFile() and DbInstall::dbControl(), combined with an SQL injection issue enabled by PDO::ATTR_EMULATE_PREPARES supporting stacked queries. Attackers can exploit the SQL injection to re-trigger the installer and inject arbitrary PHP code into config.inc.php, achieving unauthenticated remote code execution on the underlying system.
