CVE-2025-27189 in Commerce
Summary
by MITRE • 04/09/2025
Adobe Commerce versions 2.4.7-p4, 2.4.6-p9, 2.4.5-p11, 2.4.4-p12, 2.4.8-beta2 and earlier are affected by a Cross-Site Request Forgery (CSRF) vulnerability that could be exploited to cause a denial-of-service condition. An attacker could trick a logged-in user into submitting a forged request to the vulnerable application, which may disrupt service availability. Exploitation of this issue requires user interaction, typically in the form of clicking a malicious link or visiting an attacker-controlled website.

Adobe Commerce suffers from a critical cross-site request forgery vulnerability that undermines the application's security posture and service availability. This flaw affects multiple version branches including 2.4.7-p4, 2.4.6-p9, 2.4.5-p11, 2.4.4-p12, and 2.4.8-beta2, indicating a widespread issue across the product's release cycle. The vulnerability stems from insufficient validation of request origins and lack of proper anti-CSRF token implementation within the application's authentication mechanisms. When a malicious actor crafts a forged request that targets the vulnerable Commerce application, they can exploit the absence of robust CSRF protection measures to manipulate user sessions and execute unauthorized operations. The vulnerability's classification as a CSRF weakness aligns with CWE-352, which specifically addresses cross-site request forgery vulnerabilities in web applications. This particular flaw represents a significant threat to system availability as it enables attackers to perform denial-of-service attacks through legitimate user sessions, leveraging the trust relationship between the application and authenticated users. The exploitation requires user interaction, typically involving the victim clicking on a malicious link or visiting an attacker-controlled website, which demonstrates the social engineering component inherent to CSRF attacks. This attack vector is particularly dangerous because it can be executed without requiring direct access to the target system, making it an attractive method for attackers seeking to disrupt service availability. The impact extends beyond simple service disruption as the vulnerability could potentially enable more sophisticated attacks if combined with other exploitation techniques, representing a fundamental weakness in the application's session management and request validation processes. The vulnerability's presence in beta and stable releases suggests that the security controls were not properly implemented or tested during the development lifecycle, creating a persistent risk for organizations relying on these commerce platforms.
The operational impact of this CSRF vulnerability manifests as a potential disruption to critical e-commerce operations and user experience. When successfully exploited, the vulnerability allows attackers to perform unauthorized actions within the context of authenticated user sessions, potentially leading to service degradation or complete unavailability of commerce functions. The denial-of-service condition can affect various aspects of the application including user account management, order processing, inventory updates, and payment handling capabilities. Organizations utilizing affected Adobe Commerce versions face significant risk of service interruption that could result in financial losses, customer dissatisfaction, and reputational damage. The vulnerability's requirement for user interaction creates a specific attack scenario where victims must be tricked into performing malicious actions, but this limitation does not reduce the overall threat level given the prevalence of phishing and social engineering attacks in modern cybersecurity landscapes. The attack complexity is relatively low for threat actors, as the exploitation process primarily involves crafting malicious web pages or links that automatically submit forged requests to the vulnerable application. This vulnerability represents a serious concern for organizations that rely on Adobe Commerce for their online business operations, as it could be exploited to cause significant disruption to commerce activities and potentially lead to data integrity issues. The vulnerability's persistence across multiple release versions indicates that the underlying architectural flaw was not properly addressed during patch development cycles, suggesting a systemic issue in how CSRF protection is implemented within the platform's core components.
Organizations should implement comprehensive mitigation strategies to address this CSRF vulnerability and protect their Adobe Commerce deployments. Immediate remediation efforts should focus on applying the latest security patches provided by Adobe, which would include the necessary fixes for CSRF token validation and request origin checking. Network-level controls such as implementing proper Content Security Policy headers and enforcing strict origin validation can provide additional protection layers against CSRF attacks. The implementation of anti-CSRF tokens for all state-changing operations within the application represents a critical defensive measure that addresses the root cause of the vulnerability. Security teams should also conduct thorough testing to ensure that all user-facing forms and API endpoints properly validate CSRF tokens and reject requests lacking proper authentication tokens. Application-level monitoring and logging should be enhanced to detect suspicious request patterns that might indicate CSRF attack attempts. Regular security assessments should be performed to identify other potential vulnerabilities that could be exploited in conjunction with CSRF attacks, as this vulnerability could serve as a stepping stone for more advanced exploitation techniques. The mitigation approach should also include user education programs to help staff recognize and avoid potentially malicious links or websites that could be used to exploit this vulnerability. Incident response procedures should be updated to include specific protocols for detecting and responding to CSRF-related security events. Organizations should also consider implementing web application firewalls that can detect and block known CSRF attack patterns. The vulnerability's classification under ATT&CK technique T1566 highlights the importance of defending against initial access vectors that leverage social engineering and user interaction, making comprehensive defensive measures essential for protecting against this specific threat.
