Description

There is a SQL Injection vulnerability in PHP-Nuke 8.3.3 in the User Registration section, leading to remote code execution. This occurs because the U.S. state is not validated to be two letters, and the OrderBy field is not validated to be one of LASTNAME, CITY, or STATE.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')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.
