CVE-2022-24892 is a vulnerability identified in Shopware, an open-source e-commerce platform widely used for online retail operations. The affected versions range from 5.0.4 up to, but not including, 5.7.9. The vulnerability stems from a weak password recovery mechanism, specifically related to the handling of password reset tokens. In these versions, the system allows multiple password reset tokens to be requested and issued concurrently for a single user account. Critically, all issued tokens remain valid and can be used to reset the password, rather than invalidating previous tokens upon a new request. This behavior creates a security risk because if an attacker gains access to the victim's email account and locates any unused password reset token from prior requests, they can use it to take over the victim's Shopware account. The vulnerability is classified under CWE-640, which relates to weak password recovery mechanisms that do not properly invalidate or limit password reset tokens. The issue was addressed and fixed in Shopware version 5.7.9, where presumably token invalidation or stricter controls were implemented. There are no known exploits in the wild reported to date, but the risk remains significant due to the potential for account takeover if email accounts are compromised or if tokens are intercepted. The vulnerability does not require the attacker to have direct access to the Shopware platform but relies on access to the victim's email, which is often a weaker link in security chains. This vulnerability primarily affects the confidentiality and integrity of user accounts on Shopware-based e-commerce sites, potentially leading to unauthorized access, fraudulent transactions, or data theft.

For European organizations using Shopware versions between 5.0.4 and 5.7.8, this vulnerability poses a moderate risk of account takeover. The impact is particularly relevant for e-commerce businesses that rely on Shopware for customer transactions and user account management. If attackers exploit this vulnerability by leveraging access to customer or administrative email accounts, they can reset passwords and gain unauthorized access to user accounts, potentially leading to fraudulent purchases, theft of personal data, or disruption of business operations. The compromise of administrative accounts could further escalate to full control over the e-commerce platform, enabling manipulation of product listings, pricing, or customer data. Given the importance of e-commerce in the European market and the strict data protection regulations such as GDPR, such breaches could result in significant reputational damage, financial losses, and regulatory penalties. The vulnerability's reliance on email compromise means that organizations with weaker email security or insufficient monitoring of password reset processes are at higher risk. However, since exploitation requires access to email accounts, the overall risk is somewhat mitigated by the security posture of the email providers and user practices. The vulnerability does not directly affect availability but can indirectly cause service disruptions if accounts are compromised and require remediation.

To mitigate this vulnerability, European organizations should prioritize upgrading Shopware installations to version 5.7.9 or later, where the issue is resolved. If immediate upgrading is not feasible, organizations should implement compensating controls such as: 1) Enforce multi-factor authentication (MFA) on both Shopware accounts and associated email accounts to reduce the risk of unauthorized email access. 2) Monitor and limit the frequency of password reset requests per user to reduce the number of valid tokens issued concurrently. 3) Implement email security best practices, including the use of secure email gateways, anti-phishing measures, and regular audits of email account access logs. 4) Educate users and administrators about the risks of password reset token exposure and encourage prompt deletion of password reset emails after use. 5) Review and enhance logging and alerting mechanisms to detect unusual password reset activity or multiple token requests. 6) Consider deploying web application firewalls (WAFs) with rules to detect and block suspicious password reset request patterns. 7) Conduct regular security assessments and penetration testing focused on authentication and password recovery workflows. These measures, combined with patching, will significantly reduce the risk of exploitation and account compromise.
