CVE-2022-1453 Scanner

The RSVPMaker plugin is a widely used WordPress add-on that facilitates event management and RSVP functionalities for WordPress websites. It is commonly utilized by event organizers, businesses, and individuals to manage event registrations directly on their websites. The plugin integrates with WordPress, making it a popular choice for those who wish to leverage the WordPress platform's capabilities for managing events seamlessly. RSVPMaker is also often used in conjunction with email marketing tools to coordinate event promotions, making it a versatile tool for managing audience interactions. Its easy-to-use interface and compatibility with various WordPress themes make it especially appealing to non-technical users who require a straightforward event management solution.

The SQL Injection vulnerability in the RSVPMaker plugin arises due to improper sanitization and lack of SQL command escaping of user-supplied inputs. This security flaw allows attackers to manipulate SQL queries by injecting malicious SQL code, enabling unauthorized retrieval of sensitive database information. In versions up to 9.2.5, this vulnerability could lead to privacy violations, as attackers might extract confidential user data without authentication. The execution of arbitrary SQL commands may lead to extensive data exposure and potential data integrity issues, posing significant security risks for websites using the vulnerable plugin.

Technically, the vulnerability is present in the rsvpmaker-util.php file, where user-supplied input is directly incorporated into SQL queries without appropriate sanitization. The lack of parameterized queries or sufficient escaping techniques facilitates the injection of SQL commands, which can be exploited by unauthenticated users. The exploit is typically performed by embedding malicious SQL code within input parameters that are parsed by the vulnerable SQL query, leading to unauthorized access and data extraction when executed. The absence of authentication checks exacerbates the severity, making this attack vector accessible to unauthenticated users.

Exploiting this SQL Injection vulnerability can have severe consequences, including unauthorized access to sensitive information such as user credentials, payment details, and personal data. Attackers may perform data exfiltration activities, compromising the confidentiality and integrity of the database. This could potentially lead to reputational damage, financial loss, and legal implications for affected organizations, especially if protected data is involved. Furthermore, successful exploitation might pave the way for subsequent attacks, such as privilege escalation or defacement, increasing the overall impact on affected systems.
