The vulnerability EUVD-2024-37947 affects Adobe Commerce (formerly Magento) and is classified as an "Unrestricted Upload of File with Dangerous Type" vulnerability. This type of vulnerability allows an attacker to upload a malicious file to the server, which can then be executed, leading to arbitrary code execution. The severity of this vulnerability is rated with a CVSS Base Score of 9.0, indicating a critical risk.

CVSS Vector Breakdown:

• AV:N (Network Vector): The vulnerability is exploitable over the network.
• AC:H (High Attack Complexity): Exploiting this vulnerability requires a high level of skill or specific conditions.
• PR:N (No Privileges Required): No privileges are required to exploit this vulnerability.
• UI:N (No User Interaction): No user interaction is required for exploitation.
• S:C (Changed Scope): The vulnerability changes the security scope, meaning it can affect components beyond the initial security scope.
• C:H (High Confidentiality Impact): There is a high impact on the confidentiality of the data.
• I:H (High Integrity Impact): There is a high impact on the integrity of the data.
• A:H (High Availability Impact): There is a high impact on the availability of the system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Malicious File Upload: An attacker could upload a file with a dangerous type (e.g., a script or executable) to the server.
• Remote Code Execution: Once the file is uploaded, the attacker could execute it, leading to arbitrary code execution on the server.

Exploitation Methods:

• Direct Upload: The attacker could directly upload a malicious file through a vulnerable upload mechanism.
• Indirect Upload: The attacker could exploit other vulnerabilities or misconfigurations to upload the file indirectly.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of Adobe Commerce:

• 2.4.7-p1
• 2.4.6-p6
• 2.4.5-p8
• 2.4.4-p9
• Earlier versions

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by Adobe.
• Access Controls: Implement strict access controls to limit who can upload files to the server.
• File Validation: Ensure that all uploaded files are validated and sanitized to prevent dangerous file types from being uploaded.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits to identify and mitigate vulnerabilities.
• Monitoring: Implement continuous monitoring to detect and respond to suspicious activities.
• User Training: Educate users on the risks of uploading files and the importance of following security protocols.
