CVE-2024-45115: Adobe Commerce Privilege Escalation Flaw

CVE-2024-45115 Overview

CVE-2024-45115 is an Improper Authentication vulnerability affecting Adobe Commerce, Magento Open Source, and Adobe Commerce B2B. This vulnerability allows attackers to bypass authentication mechanisms and gain unauthorized access or elevated privileges within the application. The vulnerability is particularly dangerous as it does not require any user interaction to exploit, enabling attackers to remotely compromise vulnerable e-commerce installations.

Critical Impact

Unauthenticated attackers can exploit this vulnerability to gain administrative access to Adobe Commerce and Magento installations, potentially leading to complete system compromise, data theft, and unauthorized modifications to e-commerce operations.

Affected Products

• Adobe Commerce versions 2.4.7-p2, 2.4.6-p7, 2.4.5-p9, 2.4.4-p10 and earlier
• Adobe Magento Open Source versions 2.4.7-p2, 2.4.6-p7, 2.4.5-p9, 2.4.4-p10 and earlier
• Adobe Commerce B2B versions 1.4.2-p2, 1.3.5-p7, 1.3.4-p9, 1.3.3-p10 and earlier

Technical Details for CVE-2024-45115

Vulnerability Analysis

This vulnerability is classified under CWE-287 (Improper Authentication), which describes a situation where an application does not properly verify that a user has been authenticated before performing privileged operations. In the context of Adobe Commerce and Magento, this flaw exists in the authentication handling mechanism, allowing attackers to bypass the normal authentication flow entirely.

The vulnerability is exploitable over the network without requiring any prior privileges or user interaction. When successfully exploited, an attacker can gain complete control over confidentiality, integrity, and availability of the affected system. This makes it particularly dangerous for e-commerce platforms that handle sensitive customer data, payment information, and business-critical operations.

Root Cause

The root cause of CVE-2024-45115 lies in improper validation of authentication credentials or session tokens within the Adobe Commerce/Magento application framework. The authentication mechanism fails to properly verify the identity of users before granting access to privileged functionality, creating a pathway for attackers to escalate their privileges without legitimate credentials.

This type of authentication bypass typically occurs when the application relies on client-controlled data for authentication decisions, fails to implement proper session validation, or contains logic errors in the authentication flow that can be manipulated by crafted requests.

Attack Vector

The attack vector for CVE-2024-45115 is network-based, meaning attackers can exploit this vulnerability remotely without physical access to the target system. The attack has low complexity, requires no privileges, and does not depend on user interaction, making it highly accessible to potential attackers.

An attacker would typically target the authentication endpoints of a vulnerable Adobe Commerce or Magento installation, sending specially crafted requests that exploit the improper authentication validation. Upon successful exploitation, the attacker can elevate their privileges to administrative levels, gaining full control over the e-commerce platform.

The vulnerability mechanism involves bypassing the authentication verification process in Adobe Commerce and Magento. Attackers can craft requests that exploit weaknesses in the session handling or credential validation logic to gain unauthorized access. For detailed technical information, refer to the Adobe Security Advisory APSB24-73.

Detection Methods for CVE-2024-45115

Indicators of Compromise

• Unusual administrative account creation or modifications in Adobe Commerce/Magento admin panels
• Unexpected changes to user roles and permissions without authorized administrator action
• Anomalous API requests targeting authentication endpoints with malformed or missing credentials
• Log entries showing successful authentication from unexpected IP addresses or geographic locations
• Unauthorized modifications to store configurations, payment gateways, or customer data

Detection Strategies

• Monitor authentication logs for patterns indicating authentication bypass attempts, particularly failed-then-successful sequences without valid credentials
• Implement web application firewall (WAF) rules to detect and block anomalous requests to authentication endpoints
• Deploy intrusion detection systems (IDS) configured with signatures for Adobe Commerce/Magento authentication vulnerabilities
• Review access control logs for privilege escalation events, particularly new admin accounts or role changes

Monitoring Recommendations

• Enable comprehensive logging for all authentication events in Adobe Commerce/Magento
• Set up real-time alerts for administrative actions performed by newly created or modified accounts
• Monitor network traffic for unusual patterns targeting the /admin and /rest/V1 API endpoints
• Implement file integrity monitoring for critical Magento configuration files and PHP files

How to Mitigate CVE-2024-45115

Immediate Actions Required

• Immediately update Adobe Commerce to version 2.4.7-p3, 2.4.6-p8, 2.4.5-p10, or 2.4.4-p11 as applicable to your installation
• Update Magento Open Source to the corresponding patched versions
• Review all administrative accounts for unauthorized additions or modifications and disable suspicious accounts
• Audit recent authentication logs for signs of exploitation before patching
• Consider temporarily restricting access to admin panels to trusted IP addresses until patching is complete

Patch Information

Adobe has released security updates addressing this vulnerability in Security Bulletin APSB24-73. Organizations running affected versions should apply the appropriate security patches immediately:

• Adobe Commerce 2.4.7-p3 (for 2.4.7.x installations)
• Adobe Commerce 2.4.6-p8 (for 2.4.6.x installations)
• Adobe Commerce 2.4.5-p10 (for 2.4.5.x installations)
• Adobe Commerce 2.4.4-p11 (for 2.4.4.x installations)

Corresponding updates are available for Magento Open Source and Adobe Commerce B2B.

Workarounds

• Implement strict IP-based access controls to limit admin panel access to known trusted networks
• Deploy a web application firewall (WAF) with rules to detect and block authentication bypass attempts
• Enable multi-factor authentication (MFA) for all administrative accounts to add an additional security layer
• Implement network segmentation to isolate the e-commerce platform from other critical systems

# Example: Restrict admin access via .htaccess (Apache)
# Add to .htaccess in the admin directory
<RequireAny>
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
</RequireAny>
