Descriptions

The domecode function in inc/functions_post.php in MyBulletinBoard (MyBB) 1.1.2, and possibly other versions, allows remote attackers to execute arbitrary PHP code via the username field, which is used in a preg_replace function call with a /e (executable) modifier.

Secunia Research has discovered a vulnerability in MyBB, which can be exploited by malicious people to compromise a vulnerable system. Input passed to the username field when registering is not properly sanitized before being used in a "preg_replace" call with the "e" modifier in the "domecode()" function in inc/functions_post.php. This can be exploited to execute arbitrary PHP code by first registering with a specially crafted username and then previewing a post containing the "/slap" string. The vulnerability has been confirmed in version 1.1.2. Prior versions may also be affected.
