CVE-2024-8030

Comprehensive Technical Analysis of CVE-2024-8030

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-8030 CVSS Score: 9.8

The vulnerability in the Ultimate Store Kit Elementor Addons plugin, specifically versions up to and including 2.0.3, is classified as a PHP Object Injection vulnerability. This type of vulnerability occurs due to the deserialization of untrusted input, specifically via the _ultimate_store_kit_wishlist cookie. The high CVSS score of 9.8 indicates a critical severity level, reflecting the potential for significant impact if exploited.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Attack: An attacker can exploit this vulnerability without needing to authenticate, making it highly accessible.
• Deserialization of Untrusted Input: The attacker can manipulate the _ultimate_store_kit_wishlist cookie to inject malicious PHP objects.

Exploitation Methods:

• PHP Object Injection: By crafting a specially designed cookie, an attacker can inject a PHP object that, when deserialized, could lead to arbitrary code execution or other malicious actions.
• POP Chain Exploitation: Although the vulnerable plugin itself does not contain a Property-Oriented Programming (POP) chain, the presence of such a chain in other installed plugins or themes could amplify the exploitation potential. This could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

3. Affected Systems and Software Versions

Affected Software:

• Ultimate Store Kit Elementor Addons plugin versions up to and including 2.0.3.

Affected Systems:

• Any WordPress installation using the vulnerable versions of the Ultimate Store Kit Elementor Addons plugin.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update the Plugin: Ensure that the Ultimate Store Kit Elementor Addons plugin is updated to a version higher than 2.0.3.
• Disable the Plugin: If an update is not immediately available, consider disabling the plugin until a patched version is released.

Long-Term Mitigations:

• Regular Patch Management: Implement a robust patch management process to ensure all plugins and themes are kept up-to-date.
• Input Validation: Ensure that all input, including cookies, is properly validated and sanitized.
• Security Plugins: Use security plugins that provide additional layers of protection, such as firewalls and malware scanners.
• Code Review: Conduct regular code reviews and security audits of all installed plugins and themes.

5. Impact on Cybersecurity Landscape

The discovery of this vulnerability highlights the ongoing risks associated with third-party plugins and themes in content management systems like WordPress. The high CVSS score underscores the potential for severe impacts, including data breaches, unauthorized access, and system compromise. This incident serves as a reminder of the importance of continuous monitoring, regular updates, and proactive security measures in maintaining a secure cyber environment.

6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Component: The _ultimate_store_kit_wishlist cookie is used to store user wishlist data.
• Deserialization Process: The plugin deserializes the cookie data without proper validation, leading to PHP Object Injection.
• Exploitation Conditions: The absence of a POP chain in the vulnerable plugin limits direct exploitation. However, the presence of a POP chain in other installed plugins or themes can enable full exploitation.

Mitigation Steps:

• Code Review: Review the deserialization process in the plugin to ensure proper validation and sanitization of input data.
• Security Audits: Conduct thorough security audits of all installed plugins and themes to identify and mitigate similar vulnerabilities.
• Monitoring: Implement continuous monitoring to detect and respond to any suspicious activities related to the plugin.
