CVE-2025-49073

Comprehensive Technical Analysis of CVE-2025-49073

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-49073 CISA Vulnerability Name: CVE-2025-49073 Description: Deserialization of Untrusted Data vulnerability in Axiomthemes Sweet Dessert allows Object Injection. This issue affects Sweet Dessert: from n/a before 1.1.13. CVSS Score: 9.8

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for unauthenticated remote code execution (RCE), which can lead to full system compromise. The vulnerability allows an attacker to inject malicious objects into the application, potentially leading to arbitrary code execution.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Untrusted Data Deserialization: An attacker can send specially crafted serialized data to the application, which, when deserialized, can lead to object injection.
• Web Application Inputs: Any input fields, file uploads, or API endpoints that accept serialized data are potential entry points.

Exploitation Methods:

• Object Injection: By injecting malicious objects, an attacker can manipulate the application's behavior, leading to RCE.
• Payload Crafting: Crafting a payload that, when deserialized, executes arbitrary code or commands on the server.

3. Affected Systems and Software Versions

Affected Software:

• Axiomthemes Sweet Dessert WordPress theme
• Versions: All versions before 1.1.13

Affected Systems:

• Any WordPress installation using the Axiomthemes Sweet Dessert theme versions prior to 1.1.13.
• Servers hosting these WordPress installations.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update: Immediately update the Axiomthemes Sweet Dessert theme to version 1.1.13 or later.
• Disable Deserialization: If updating is not possible, disable the deserialization of untrusted data.

Long-Term Strategies:

• Input Validation: Implement strict input validation and sanitization for all user inputs.
• Serialization Libraries: Use secure serialization libraries that do not allow object injection.
• Monitoring: Implement monitoring and logging to detect and respond to suspicious activities.

5. Impact on Cybersecurity Landscape

Broader Implications:

• Widespread Use: Given the popularity of WordPress and its themes, this vulnerability can affect a large number of websites.
• Supply Chain Risk: Highlights the risk of third-party components and the importance of regular updates and patch management.
• Exploit Development: The high CVSS score and the nature of the vulnerability make it a prime target for exploit development by threat actors.

6. Technical Details for Security Professionals

Technical Overview:

• Deserialization Process: The vulnerability arises from the deserialization of untrusted data, which can be manipulated to inject malicious objects.
• Object Injection: The injected objects can be used to execute arbitrary code, leading to RCE.

Detection and Response:

• Intrusion Detection Systems (IDS): Configure IDS to detect unusual deserialization activities.
• Web Application Firewalls (WAF): Use WAF to block suspicious serialized data inputs.
• Code Review: Conduct a thorough code review to identify and mitigate similar vulnerabilities in other parts of the application.

Example Exploit Scenario:

1. An attacker identifies a vulnerable input field in the Sweet Dessert theme.
2. The attacker crafts a serialized payload containing a malicious object.
3. The payload is sent to the application, which deserializes it.
4. The malicious object executes arbitrary code, leading to RCE.

Conclusion: CVE-2025-49073 represents a critical vulnerability that requires immediate attention. Organizations using the affected theme should prioritize updates and implement robust security measures to mitigate the risk. The broader cybersecurity community should take note of the potential for similar vulnerabilities in other applications and themes, emphasizing the need for proactive security practices.
