CVE-2024-10628 identifies a SQL Injection vulnerability in the AYS Pro Plugins Quiz Maker Business, Developer, and Agency WordPress plugins. The vulnerability exists due to insufficient escaping and lack of prepared statements for the 'id' parameter in SQL queries, allowing attackers to append arbitrary SQL commands. This flaw affects all versions up to 8.8.0 for Business, 21.8.0 for Developer, and 31.8.0 for Agency plugins. An unauthenticated attacker can exploit this remotely by sending crafted requests that manipulate the SQL query logic, enabling unauthorized access to sensitive data stored in the backend database. The vulnerability does not require authentication or user interaction, increasing its risk profile. Despite no known active exploitation, the vulnerability's presence in widely used WordPress plugins poses a significant threat. The shared plugin slug across the three plugin variants may trigger alerts even on patched versions, necessitating careful version verification. The CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) indicates a high-severity issue with a network attack vector, low attack complexity, no privileges or user interaction required, and a high impact on confidentiality but no impact on integrity or availability.

The primary impact of this vulnerability is unauthorized disclosure of sensitive information from the affected WordPress site's database. Attackers can extract data such as user credentials, personal information, or other confidential content stored in the database. This can lead to privacy violations, data breaches, and potential compliance issues for organizations. Since the vulnerability is exploitable without authentication or user interaction, it increases the attack surface significantly, allowing automated exploitation at scale. The integrity and availability of the system are not directly affected, but the loss of confidentiality can damage organizational reputation and trust. Organizations relying on these plugins for quiz or survey functionality may face targeted attacks, especially if they store sensitive user data. The widespread use of WordPress globally means that many small to medium businesses, educational institutions, and enterprises could be impacted. The lack of known exploits in the wild currently provides a window for remediation before active attacks emerge.

Organizations should immediately verify the installed versions of the AYS Pro Plugins Quiz Maker Business, Developer, and Agency plugins and upgrade to versions beyond 8.8.0 (Business), 21.8.0 (Developer), or 31.8.0 (Agency) where the vulnerability is patched. If updates are not yet available, consider temporarily disabling the affected plugins or restricting access to the vulnerable endpoints via web application firewalls (WAFs) with custom rules blocking suspicious 'id' parameter inputs. Employ input validation and sanitization at the application level to reject unexpected characters in parameters. Monitor web server logs for unusual query patterns indicative of SQL injection attempts. Implement database user permissions with least privilege to limit data exposure in case of exploitation. Regularly audit and scan WordPress sites using security plugins that detect SQL injection vulnerabilities. Educate site administrators about the shared plugin slug issue to avoid false positives and ensure proper patch verification. Finally, maintain regular backups to enable recovery if a breach occurs.
