Summary
by MITRE • 08/14/2024
Adobe Commerce versions 2.4.7-p1, 2.4.6-p6, 2.4.5-p8, 2.4.4-p9 and earlier are affected by an Unrestricted Upload of File with Dangerous Type vulnerability that could result in arbitrary code execution by an attacker. An attacker could exploit this vulnerability by uploading a malicious file which can then be executed on the server. Exploitation of this issue does not require user interaction, but attack complexity is high and scope is changed.

The vulnerability identified as CVE-2024-39397 represents a critical security flaw in Adobe Commerce platforms affecting multiple version releases including 2.4.7-p1, 2.4.6-p6, 2.4.5-p8, 2.4.4-p9 and earlier versions. This issue manifests as an unrestricted file upload vulnerability that permits malicious actors to bypass normal file validation mechanisms and upload potentially harmful files to the server infrastructure. The vulnerability falls under the category of unrestricted file upload attacks where attackers can upload files with dangerous types that may execute arbitrary code on the target system, fundamentally compromising the platform's security posture and potentially leading to complete system compromise.
The technical implementation of this vulnerability stems from insufficient validation of file types during the upload process within the Adobe Commerce application. When users or attackers attempt to upload files through the platform's file handling mechanisms, the system fails to properly verify the content type and file extensions of uploaded files. This weakness allows attackers to upload files with extensions such as .php, .asp, .jsp, or other executable formats that the server will process and execute as legitimate code. The flaw operates at the application layer where proper input validation and file type checking mechanisms are either absent or inadequately implemented, creating a pathway for malicious code execution.
The operational impact of CVE-2024-39397 extends far beyond simple data compromise, as successful exploitation can lead to complete system takeover and persistent backdoor access. An attacker who successfully exploits this vulnerability can execute arbitrary commands on the affected server, potentially gaining administrative privileges and establishing long-term access to the commerce platform's infrastructure. The vulnerability's classification as requiring no user interaction makes it particularly dangerous as it can be exploited automatically without requiring victims to perform specific actions. However, the high attack complexity requirement suggests that exploitation may involve sophisticated techniques, though the potential for automated exploitation remains significant given the severity of the impact. The changed scope aspect indicates that successful exploitation could affect multiple system components beyond the immediate application layer.
Organizations utilizing affected Adobe Commerce versions must implement immediate mitigation strategies to address this vulnerability. The primary recommended approach involves applying the latest security patches and updates provided by Adobe to remediate the file upload validation flaws. Additionally, implementing strict file type validation mechanisms, enforcing proper file extension filtering, and configuring web servers to reject executable file uploads are essential defensive measures. Network segmentation and monitoring solutions should be deployed to detect suspicious file upload activities and anomalous behavior patterns. The vulnerability aligns with CWE-434 which specifically addresses unrestricted upload of file with dangerous type, and represents a technique commonly associated with attack patterns in the MITRE ATT&CK framework under the initial access and execution phases. Organizations should also consider implementing web application firewalls and content security policies to provide additional layers of protection against similar vulnerabilities in the future.
