EUVD-2025-2987

Comprehensive Technical Analysis of EUVD-2025-2987

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability identified as EUVD-2025-2987 pertains to a Deserialization of Untrusted Data issue in the GiveWP plugin for WordPress. This vulnerability allows for Object Injection, which can lead to severe security implications.

Severity Evaluation: The Base Score of 9.8, as per CVSS:3.1, indicates a critical severity level. The scoring vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal complexity.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - The vulnerability has a high impact on confidentiality.
• Integrity (I): High (H) - The vulnerability has a high impact on integrity.
• Availability (A): High (H) - The vulnerability has a high impact on availability.

Given these metrics, the vulnerability is considered highly critical and poses a significant risk to affected systems.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Since the attack vector is network-based, an attacker can exploit the vulnerability remotely without needing physical access to the system.
• Untrusted Data Deserialization: The primary attack vector involves the deserialization of untrusted data, which can be manipulated to inject malicious objects.

Exploitation Methods:

• Object Injection: An attacker can craft a serialized object that, when deserialized, executes arbitrary code or manipulates the application's state.
• Remote Code Execution (RCE): By injecting malicious objects, an attacker can achieve remote code execution, leading to complete control over the affected system.

3. Affected Systems and Software Versions

Affected Software:

• GiveWP Plugin for WordPress: Versions from n/a through 3.19.3 are affected.

Affected Systems:

• WordPress Websites: Any WordPress installation using the affected versions of the GiveWP plugin is at risk.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update the Plugin: Ensure that the GiveWP plugin is updated to a version that addresses this vulnerability.
• Disable the Plugin: If an update is not immediately available, consider disabling the plugin until a patch is released.

Long-Term Mitigation:

• Input Validation: Implement strict input validation to ensure that only trusted data is deserialized.
• Serialization Libraries: Use secure serialization libraries that provide protection against object injection.
• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.

5. Impact on European Cybersecurity Landscape

Regulatory Compliance:

• GDPR: The vulnerability poses a risk to personal data, which could result in GDPR violations and potential fines.
• NIS Directive: Organizations in critical sectors must ensure compliance with the NIS Directive, which mandates robust cybersecurity measures.

Economic Impact:

• Business Disruption: Exploitation of this vulnerability can lead to significant business disruptions, including data breaches and service outages.
• Reputation Damage: Organizations affected by this vulnerability may suffer reputational damage, leading to loss of customer trust.

6. Technical Details for Security Professionals

Technical Analysis:

• Deserialization Process: The vulnerability arises from the deserialization process, where untrusted data is converted into an object. This process can be manipulated to inject malicious objects.
• Object Injection: The injected objects can execute arbitrary code, leading to various security issues such as data exfiltration, system compromise, and unauthorized access.

Detection and Monitoring:

• Log Analysis: Monitor logs for unusual deserialization activities and unexpected object creation.
• Intrusion Detection Systems (IDS): Implement IDS to detect and alert on suspicious network activities related to deserialization.

Patch Management:

• Automated Updates: Ensure that automated update mechanisms are in place to apply patches as soon as they are released.
• Vulnerability Scanning: Regularly scan for vulnerabilities using tools that can identify and report on deserialization issues.

Conclusion: The EUVD-2025-2987 vulnerability in the GiveWP plugin is a critical issue that requires immediate attention. Organizations must prioritize updating the plugin and implementing robust security measures to mitigate the risk. The potential impact on the European cybersecurity landscape underscores the importance of proactive cybersecurity practices and compliance with regulatory requirements.
