EUVD-2025-24539

Comprehensive Technical Analysis of EUVD-2025-24539

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-24539 pertains to a PHP Object Injection flaw in the Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress. This vulnerability is present in all versions up to and including 1.4.3. The issue arises from the deserialization of untrusted input in the get_lead_detail function, which can be exploited by unauthenticated attackers to inject a PHP Object.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates a critical vulnerability due to the following factors:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit this vulnerability without needing any authentication.
• Deserialization of Untrusted Input: The get_lead_detail function processes untrusted input, leading to PHP Object Injection.

Exploitation Methods:

• PHP Object Injection: By crafting a malicious serialized object, attackers can inject PHP code.
• POP Chain Exploitation: The presence of a Property-Oriented Programming (POP) chain in the Contact Form 7 plugin allows attackers to delete arbitrary files, including critical files like wp-config.php.

Potential Outcomes:

• Denial of Service (DoS): Deletion of critical files can lead to service disruption.
• Remote Code Execution (RCE): If attackers can delete wp-config.php, they may gain the ability to execute arbitrary code on the server.

3. Affected Systems and Software Versions

Affected Software:

• Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress

Affected Versions:

• All versions up to and including 1.4.3

Vendor:

• crmperks

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Plugin: Upgrade to a version higher than 1.4.3 if available.
• Disable Plugin: If an update is not available, consider disabling the plugin until a patch is released.

Long-Term Mitigations:

• Input Validation: Ensure all input is properly validated and sanitized.
• Serialization Security: Avoid deserializing untrusted data. Use secure deserialization libraries if necessary.
• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Monitoring: Implement monitoring and logging to detect and respond to suspicious activities.
