CVE-2019-14230
An issue was discovered in the Viral Quiz Maker – OnionBuzz plugin before 1.2.7 for WordPress. One could exploit the id parameter in the set_count ajax nopriv handler due to there being no sanitization prior to use in a SQL query in saveQuestionVote. This allows an unauthenticated/unprivileged user to perform a SQL injection attack capable of remote code execution and information disclosure.
