Multiple SQL injection vulnerabilities in vBulletin 3.7.4 allow remote authenticated administrators to execute arbitrary SQL commands via the (1) answer parameter to admincp/verify.php, (2) extension parameter in an edit action to admincp/attachmentpermission.php, and the (3) iperm parameter to admincp/image.php.
Improper Neutralization of Special Elements used in an SQL Command The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
