ZeroBoard is a freely available, open source PHP-based bulletin board software, and widely used in Korea. ZeroBoard version 4.1pl4 and earlier are vulnerable to multiple PHP source injection and cross-site scripting vulnerabilities as follows:

1. A Remote PHP File Include Vulnerability in the outlogin.php could allow a remote attacker to execute arbitrary external PHP code.
2. A Remote PHP File Include Vulnerability in the write.php could allow a remote attacker to execute arbitrary external PHP code.
