CVE-2022-24742 in Sylius
Summary
by MITRE • 03/15/2022
Sylius is an open source eCommerce platform. Prior to versions 1.9.10, 1.10.11, and 1.11.2, any other user can view the data if browser tab remains unclosed after log out. The issue is fixed in versions 1.9.10, 1.10.11, and 1.11.2. A workaround is available. The application must strictly redirect to login page even browser back button is pressed. Another possibility is to set more strict cache policies for restricted content.

The vulnerability identified as CVE-2022-24742 affects the Sylius eCommerce platform, an open source solution widely used for online commerce operations. This security flaw represents a critical session management issue that allows unauthorized access to sensitive user data even after logout operations. The vulnerability specifically impacts versions prior to 1.9.10, 1.10.11, and 1.11.2, where proper session termination mechanisms fail to prevent data exposure through browser navigation behaviors. The flaw stems from inadequate handling of browser navigation after authentication termination, creating a window where cached content remains accessible to subsequent users who might access the same browser tab.
The technical root cause of this vulnerability lies in the application's failure to implement proper session invalidation and cache control mechanisms. When users log out of the Sylius platform, the system does not effectively clear session data or enforce cache policies that would prevent access to restricted content. This behavior creates a session fixation scenario where browser caching retains access to previously authenticated data, allowing any user who opens the same browser tab to view sensitive information without proper authentication. The vulnerability manifests through browser back navigation functionality, where the application fails to enforce proper access controls when users return to previously visited authenticated pages.
The operational impact of CVE-2022-24742 extends beyond simple data exposure to encompass potential financial fraud, customer privacy violations, and regulatory compliance breaches. Attackers could exploit this vulnerability to access customer orders, payment information, personal details, and other sensitive business data simply by navigating back to cached pages after legitimate users have logged out. This risk is particularly concerning in shared computing environments where multiple users might access the same browser instance, or in public computing facilities where session management is not properly enforced. The vulnerability creates a persistent security gap that could be exploited for extended periods if not properly addressed through version updates or workaround implementations.
The fix for this vulnerability involves implementing strict redirect mechanisms that ensure users are properly redirected to login pages regardless of browser navigation actions. This approach aligns with security best practices outlined in CWE-613 and addresses the specific issue of inadequate session management. Organizations should implement proper cache control headers that prevent caching of sensitive content, utilize HTTP cache-control directives, and enforce strict session invalidation protocols. The recommended mitigation includes setting appropriate cache policies for restricted content, ensuring that browser back buttons cannot access cached authenticated pages, and implementing comprehensive session management that properly terminates user sessions upon logout. These measures directly correspond to ATT&CK techniques focused on privilege escalation and credential access through session management weaknesses, making them essential for maintaining platform security and compliance with industry standards.
