Unspecified vulnerability in phpBB before 3.0.1 has unknown impact and attack vectors related to "urls gone through redirect() being used within login_box()."

Multiple unspecified vulnerabilities in phpBB before 3.0.1 have unknown impact and attack vectors, related to "two minor security-related bugs."

PHP remote file inclusion vulnerability in link_main.php in the SupaNav 1.0.0 module for phpBB allows remote attackers to execute arbitrary PHP code via a URL in the phpbb_root_path parameter.

PHP remote file inclusion vulnerability in includes/functions.php in the Dimension module of phpBB allows remote attackers to execute arbitrary PHP code via a URL in the phpbb_root_path parameter. NOTE: this may be the same issue as CVE-2006-5235.

PHP remote file inclusion vulnerability in includes/bb_usage_stats.php in maluinfo 206.2.38 for Brazilian PHPBB allows remote attackers to execute arbitrary PHP code via the phpbb_root_path parameter. NOTE: this might be the same issues as CVE-2006-4893.
