CVE-2025-7384

Comprehensive Technical Analysis of CVE-2025-7384

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-7384 CVSS Score: 9.8

The vulnerability in the Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress is classified as a PHP Object Injection vulnerability. This type of vulnerability is particularly severe due to its potential for remote code execution (RCE) and denial of service (DoS) attacks. The CVSS score of 9.8 indicates a critical severity level, underscoring the urgent need for mitigation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Attackers: The vulnerability allows unauthenticated attackers to exploit the deserialization of untrusted input in the get_lead_detail function.
• PHP Object Injection: Attackers can inject malicious PHP objects, which can lead to arbitrary code execution.
• POP Chain Exploitation: The presence of a Property-Oriented Programming (POP) chain in the Contact Form 7 plugin can be leveraged to delete arbitrary files, including critical files like wp-config.php.

Exploitation Methods:

• Deserialization Attack: By sending crafted input to the vulnerable function, attackers can trigger the deserialization process, injecting a PHP object.
• File Deletion: Using the POP chain, attackers can delete files, potentially leading to a DoS condition or RCE if critical files are targeted.

3. Affected Systems and Software Versions

Affected Software:

• Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress
• All versions up to and including 1.4.3

Affected Systems:

• WordPress installations using the vulnerable plugin versions.
• Systems where the Contact Form 7 plugin is also installed, as it contains the POP chain necessary for full exploitation.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Plugins: Ensure that all affected plugins are updated to versions that address the vulnerability.
• Disable Vulnerable Plugins: If updates are not available, consider disabling the vulnerable plugins until a patch is released.
• Monitoring: Implement monitoring for suspicious activities, such as unusual file deletions or modifications.

Long-Term Strategies:

• Regular Updates: Maintain a regular update schedule for all plugins and WordPress core.
