Description

In phpMyAdmin 4 before 4.9.4 and 5 before 5.0.1, SQL injection exists in the user accounts page. A malicious user could inject custom SQL in place of their own username when creating queries to this page. An attacker must have a valid MySQL account to access the server.

• 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.
