CVE-2022-24879 in Shopware
Summary
by MITRE • 04/28/2022
Shopware is an open source e-commerce software platform. Versions prior to 5.7.9 are vulnerable to malfunction of cross-site request forgery (CSRF) token validation. Under certain circumstances, the CSRF tokens were not generated anew and not validated correctly. This issue is fixed in version 5.7.9. Users of older versions may attempt to mitigate the vulnerability by using the Shopware security plugin.

Shopware versions prior to 5.7.9 contain a critical cross-site request forgery vulnerability that compromises the integrity of the platform's security mechanisms. This vulnerability stems from improper implementation of CSRF token validation processes within the e-commerce platform's authentication framework. The flaw allows attackers to bypass the protective measures designed to prevent unauthorized actions from being executed on behalf of authenticated users. The vulnerability specifically affects the generation and validation of CSRF tokens, which are essential components in preventing malicious actors from exploiting legitimate user sessions.
The technical implementation of the CSRF protection mechanism in affected Shopware versions fails to properly regenerate tokens for each user session or request, creating a persistent vulnerability that remains exploitable throughout the duration of a session. This flaw directly relates to CWE-352, which categorizes cross-site request forgery vulnerabilities as those involving insufficient CSRF protection mechanisms. The improper token handling creates a scenario where attackers can predict or reuse valid CSRF tokens, effectively undermining the core security principle that prevents unauthorized actions from being performed without explicit user consent.
The operational impact of this vulnerability extends beyond simple session hijacking, as it allows attackers to perform authenticated actions on behalf of legitimate users. This includes but is not limited to modifying product information, processing unauthorized transactions, accessing sensitive customer data, and potentially escalating privileges within the platform. Attackers could leverage this vulnerability to execute a wide range of malicious activities that would normally require explicit user authorization, making it particularly dangerous for e-commerce environments where financial transactions and customer data are processed. The vulnerability's persistence across sessions means that once exploited, the impact can continue until the affected system is properly updated or patched.
Organizations running vulnerable Shopware installations should immediately implement the official security patch available in version 5.7.9, which addresses the CSRF token generation and validation issues through proper session management protocols. The recommended mitigation strategy involves comprehensive system updates and thorough testing of the patched environment to ensure all security mechanisms function correctly. Additionally, users of older versions can temporarily implement the Shopware security plugin as a workaround, though this represents only a temporary solution until full patch deployment occurs. Security teams should also conduct thorough vulnerability assessments to identify any potential exploitation attempts and implement network monitoring to detect suspicious activities that may indicate attempted exploitation of this CSRF vulnerability. This vulnerability aligns with ATT&CK technique T1566.002 which covers phishing with malicious attachments and links, as attackers could potentially use CSRF attacks to establish persistence or escalate privileges within compromised e-commerce environments.
