CVE-2022-24733 in Sylius
Summary
by MITRE • 03/14/2022
Sylius is an open source eCommerce platform. Prior to versions 1.9.10, 1.10.11, and 1.11.2, it is possible for a page controlled by an attacker to load the website within an iframe. This will enable a clickjacking attack, in which the attacker's page overlays the target application's interface with a different interface provided by the attacker. The issue is fixed in versions 1.9.10, 1.10.11, and 1.11.2. A workaround is available. Every response from app should have an X-Frame-Options header set to: ``sameorigin``. To achieve that, add a new `subscriber` in the app.

CVE-2022-24733 represents a critical clickjacking vulnerability affecting the Sylius eCommerce platform across multiple version lines. This vulnerability stems from the absence of proper frame-blocking mechanisms in the application's HTTP response headers, specifically the missing X-Frame-Options header that should prevent the application from being embedded within iframes on external domains. The flaw allows attackers to craft malicious pages that load the Sylius application within hidden iframes, creating a deceptive user experience where legitimate interface elements are overlaid with attacker-controlled content. This technique enables attackers to trick users into performing unintended actions on the vulnerable platform, potentially compromising user accounts, processing unauthorized transactions, or extracting sensitive data through carefully crafted clickjacking attacks that exploit the application's interactive elements.
The technical implementation of this vulnerability involves the application's failure to enforce proper content security policies through HTTP headers. Without the X-Frame-Options header set to 'sameorigin', the browser cannot prevent the application from being embedded in iframes from different origins, making it susceptible to overlay attacks. The vulnerability aligns with CWE-1021, which specifically addresses "Improper Restriction of Rendered UI Layers or Frames", and represents a classic example of insufficient frame protection mechanisms. Attackers can leverage this weakness by creating a malicious webpage that loads the target Sylius application within an iframe positioned over the legitimate interface elements, making users believe they are interacting with the legitimate application while actually performing actions on the attacker's controlled overlay.
The operational impact of this vulnerability extends beyond simple interface manipulation to encompass potential data compromise and user deception. Users interacting with the vulnerable platform may unknowingly perform actions such as placing orders, modifying account settings, or transferring funds through the attacker's manipulated interface. The vulnerability affects the core user experience and trust model of the eCommerce platform, potentially leading to financial losses, reputational damage, and regulatory compliance issues. This attack vector particularly threatens customer-facing administrative functions and transactional processes where user interaction is required, making it a significant concern for any online commerce platform handling sensitive user data and financial transactions. The vulnerability's presence undermines the platform's security posture and could facilitate more sophisticated attacks when combined with other weaknesses.
The recommended mitigation strategy involves implementing proper HTTP response headers to prevent frame embedding, specifically setting the X-Frame-Options header to 'sameorigin' for all application responses. This approach directly addresses the root cause by instructing browsers to prevent the application from being rendered within iframes from external origins. The workaround requires developers to add a new subscriber to the application's event system that automatically injects this header into all HTTP responses, ensuring comprehensive protection across the entire platform. This solution aligns with the ATT&CK framework's defense evasion techniques and represents a standard security hardening practice for web applications. The vulnerability's resolution through version updates demonstrates the importance of maintaining current security patches and implementing proactive security measures that prevent the exploitation of known weaknesses in web frameworks and applications. Organizations should also consider implementing Content Security Policy headers as additional defense layers to provide more comprehensive protection against similar vulnerabilities.
