An issue was discovered in the Viral Quiz Maker - OnionBuzz plugin before 1.2.2 for WordPress. One could exploit the points parameter in the ob_get_results ajax nopriv handler due to there being no sanitization prior to use in a SQL query in getResultByPointsTrivia. This allows an unauthenticated/unprivileged user to perform a SQL injection attack capable of remote code execution and information disclosure.
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.
