4) Description of Vulnerability
Secunia Research has discovered some vulnerabilities in CJ Tag Board,
which can be exploited by malicious people to compromise a vulnerable
system.
1) Input passed to the "User-Agent" HTTP header in tag.php is not
properly sanitised before being stored. This can be exploited to
inject arbitrary PHP code, which is executed when requesting the
all.php script.
2) Input passed to the "banned" parameter in admin_index.php is not
properly sanitised before being stored. This can be exploited to
inject arbitrary PHP code, but requires administrative user
privileges.
