Description

Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. Versions prior to 20.12.3 and 20.13.0 contain a vulnerability that allows script execution in the admin panel which could lead to cross-site scripting against authenticated admin users. The attack requires an admin user with configuration access, so in practicality it is not very likely to be useful given that a user with this level of access is probably already a full admin. Versions 20.12.3 and 20.13.0 contain a patch for the issue.

Technical Analysis

CVE-2025-27400 is a cross-site scripting (XSS) vulnerability identified in OpenMage's Magento Long Term Support (LTS) e-commerce platform, specifically affecting versions prior to 20.12.3. Magento LTS is a community-driven fork of the Magento Community Edition, designed to maintain backward compatibility for merchants relying on the platform. The vulnerability stems from improper neutralization of input during web page generation within the admin panel, allowing malicious scripts to be injected and executed. This XSS flaw requires an authenticated admin user with configuration access to be exploited, which limits the attack surface to users who already possess elevated privileges. The vulnerability could allow an attacker to execute arbitrary scripts in the context of the admin panel session, potentially leading to limited integrity and availability impacts such as unauthorized configuration changes or disruption of admin operations. However, confidentiality impact is rated as none since the vulnerability does not directly expose sensitive data. The CVSS 3.1 base score is 2.9 (low severity), reflecting the high attack complexity, requirement for high privileges, and the need for user interaction (the admin must trigger the malicious input). No known exploits are currently reported in the wild. The issue was patched in versions 20.12.3 and 20.13.0, and users are advised to upgrade to these or later versions to remediate the vulnerability.

Potential Impact

For European organizations using OpenMage Magento LTS, the primary risk is to the integrity and availability of the e-commerce platform's administrative functions. Since exploitation requires an authenticated admin with configuration access, the threat is mostly internal or from compromised admin accounts. Successful exploitation could allow attackers to inject malicious scripts that alter configurations, disrupt admin workflows, or potentially facilitate further attacks such as session hijacking or privilege escalation within the admin context. While the confidentiality impact is minimal, disruption to the admin panel could affect business operations, order processing, and customer trust. Given the widespread use of Magento-based platforms in European retail and e-commerce sectors, organizations relying on OpenMage LTS without patching are exposed to targeted attacks, especially if internal account security is weak. The low CVSS score suggests limited external threat but does not eliminate risk from insider threats or compromised credentials.

Mitigation Recommendations

1. Immediate upgrade to OpenMage Magento LTS version 20.12.3 or later to apply the official patch addressing CVE-2025-27400. 2. Enforce strict access controls and multi-factor authentication (MFA) for all admin users to reduce the risk of credential compromise. 3. Conduct regular audits of admin accounts and permissions to ensure only necessary users have configuration access. 4. Implement Content Security Policy (CSP) headers in the admin panel to restrict execution of unauthorized scripts, mitigating potential XSS impact. 5. Monitor admin panel logs for unusual activity or script injection attempts. 6. Educate administrators on safe input handling and the risks of executing untrusted content within the admin interface. 7. Consider network segmentation to isolate the admin panel from general user access and reduce exposure. These steps go beyond generic patching by focusing on reducing the likelihood of credential compromise and limiting the impact of any successful exploitation.
