CVE-2024-7702 in Contact Form Plugin
Summary
by MITRE • 08/20/2024
The Contact Form by Bit Form: Multi Step Form, Calculation Contact Form, Payment Contact Form & Custom Contact Form builder plugin for WordPress is vulnerable to generic SQL Injection via the entryID parameter in versions 2.0 to 2.13.9 due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries to already existing queries that can be used to extract sensitive information from the database.

The vulnerability CVE-2024-7702 affects the Contact Form by Bit Form plugin for WordPress, specifically targeting versions 2.0 through 2.13.9. This security flaw resides within the plugin's handling of the entryID parameter, which is used in database operations. The issue stems from inadequate input validation and sanitization practices, creating a pathway for malicious SQL injection attacks. The vulnerability is particularly concerning because it requires only authenticated access with administrator-level privileges or higher, making it accessible to users who already have significant control over the WordPress installation. This makes the attack vector more plausible in scenarios where administrative credentials might be compromised through social engineering, credential theft, or other means.
The technical implementation of this vulnerability follows a classic SQL injection pattern where the entryID parameter is directly incorporated into SQL queries without proper escaping or parameterization. According to CWE-89, this represents a direct code injection vulnerability that allows attackers to manipulate database queries through crafted input. The lack of sufficient preparation on existing SQL queries means that the plugin fails to properly sanitize user input before executing database operations, creating opportunities for attackers to inject malicious SQL code. The vulnerability specifically targets the entryID parameter, which suggests that it occurs during the processing of form entries or related database operations within the contact form functionality.
The operational impact of this vulnerability is significant for WordPress administrators and site owners who rely on the Bit Form plugin for their contact form management. Attackers with administrator privileges can leverage this vulnerability to extract sensitive information from the database, potentially accessing user credentials, personal data, payment information, or other confidential data stored within the WordPress installation. The attack surface is broad since the vulnerability affects multiple versions of the plugin, increasing the potential number of affected sites. This SQL injection vulnerability could enable attackers to perform unauthorized data access, data modification, or even complete database compromise, depending on the privileges of the database user account. The fact that this requires only administrator-level access makes it particularly dangerous as it bypasses many standard security measures that might protect against less privileged attacks.
Mitigation strategies for CVE-2024-7702 should prioritize immediate plugin updates to versions that address the SQL injection vulnerability. System administrators should ensure that all instances of the Bit Form plugin are updated to the latest stable release that contains proper input sanitization and parameterization of database queries. Additionally, implementing proper access controls and monitoring for unusual database activity can help detect potential exploitation attempts. According to ATT&CK framework, this vulnerability would be categorized under T1078 for valid accounts and T1566 for credential harvesting, indicating that monitoring for unauthorized database access patterns is crucial. Organizations should also consider implementing database query logging and access controls to limit the potential impact of such vulnerabilities. Regular security audits and vulnerability assessments should include checks for similar SQL injection patterns in other plugins and themes to prevent cascading security issues across the WordPress ecosystem. The vulnerability demonstrates the critical importance of proper input validation and parameterized queries in preventing database-level attacks, aligning with industry best practices outlined in OWASP Top Ten and other security standards.
