member2.php in vBulletin 2.2.9 and earlier does not properly restrict the $perpage variable to be an integer, which causes an error message to be reflected back to the user without quoting, which facilitates cross-site scripting (XSS) and possibly other attacks.
Weaknesses in this category are related to improper calculation or conversion of numbers.
