CVE-2022-21652 in Shopware
Summary
by MITRE • 01/05/2022
Shopware is an open source e-commerce software platform. In affected versions shopware would not invalidate a user session in the event of a password change. With version 5.7.7 the session validation was adjusted, so that sessions created prior to the latest password change of a customer account can't be used to login with said account. This also means, that upon a password change, all existing sessions for a given customer account are automatically considered invalid. There is no workaround for this issue.

The vulnerability identified as CVE-2022-21652 affects Shopware, an open-source e-commerce platform that serves millions of online businesses worldwide. This security flaw represents a critical session management weakness that directly impacts user authentication integrity. The issue stems from the platform's failure to properly invalidate user sessions when password changes occur, creating a persistent security gap that could allow unauthorized access to customer accounts. The vulnerability specifically affects versions prior to 5.7.7, where the session validation mechanism was insufficient to prevent the use of stale sessions following password modifications.
The technical flaw manifests in the session invalidation process within Shopware's authentication system. When a user changes their password, the platform should immediately invalidate all existing sessions associated with that account to prevent session hijacking attacks. However, in vulnerable versions, sessions created before the password change remain valid and can still be used to authenticate to the compromised account. This design oversight creates a window of opportunity for attackers who may have obtained session tokens through various means such as network sniffing, cross-site scripting attacks, or session fixation vulnerabilities. The vulnerability directly maps to CWE-613, which addresses insufficient session expiration, and aligns with ATT&CK technique T1531 for Account Access Removal and T1078 for Valid Accounts.
The operational impact of this vulnerability extends beyond simple session management issues to encompass broader account compromise risks. Attackers who gain access to valid session tokens can maintain persistent access to customer accounts even after password changes, effectively bypassing the intended security controls. This scenario becomes particularly dangerous in environments where session tokens are stored in client-side storage or transmitted over insecure channels. The vulnerability also impacts the principle of least privilege and proper access control enforcement, as users may retain access to resources they should no longer be authorized to access. Organizations using affected Shopware versions face potential data breaches, unauthorized transactions, and customer trust erosion, with the risk amplifying if attackers can leverage this weakness to escalate privileges or access sensitive administrative functions.
The remediation strategy for CVE-2022-21652 requires immediate upgrade to Shopware version 5.7.7 or later, which implements proper session invalidation upon password changes. This update ensures that all existing sessions for a customer account become immediately invalid whenever a password is modified, effectively closing the security gap. Organizations should also conduct comprehensive security assessments of their Shopware installations to identify any potential session token leakage or storage vulnerabilities that could compound the risk. Additional mitigations include implementing secure session token storage mechanisms, enforcing secure transmission protocols such as HTTPS with proper certificate validation, and establishing monitoring procedures to detect unusual authentication patterns. Security teams should also consider implementing session timeout mechanisms and regular session validation checks as part of their overall security posture. The vulnerability demonstrates the critical importance of proper session management in web applications and highlights the necessity of adhering to security best practices such as those outlined in the OWASP Top Ten and NIST Special Publication 800-63B for identity and access management.
