[原文]Multiple SQL injection vulnerabilities in MyBulletinBoard (MyBB) Preview Release 2 allow remote attackers to execute arbitrary SQL commands via the (1) fid parameter to misc.php or (2) Content-Disposition field in the HTTP header to newreply.php.
MyBB contains a flaw that may allow a remote attacker to carry out an SQL injection attack. The issue is due to the 'misc.php' script not properly sanitizing user-supplied input to the 'fid' variable. This may allow a remote attacker to inject or manipulate SQL queries in the back-end database.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
