CVE-2024-31205 in Saleor
Summary
by MITRE • 04/08/2024
Saleor is an e-commerce platform. Starting in version 3.10.0 and prior to versions 3.14.64, 3.15.39, 3.16.39, 3.17.35, 3.18.31, and 3.19.19, an attacker may bypass cross-set request forgery (CSRF) validation when calling refresh token mutation with empty string. When a user provides an empty string in `refreshToken` mutation, while the token persists in `JWT_REFRESH_TOKEN_COOKIE_NAME` cookie, application omits validation against CSRF token and returns valid access token. Versions 3.14.64, 3.15.39, 3.16.39, 3.17.35, 3.18.31, and 3.19.19 contain a patch for the issue. As a workaround, one may replace `saleor.graphql.account.mutations.authentication.refresh_token.py.get_refresh_token`. This will fix the issue, but be aware, that it returns `JWT_MISSING_TOKEN` instead of `JWT_INVALID_TOKEN`.

The vulnerability described in CVE-2024-31205 affects the Saleor e-commerce platform, specifically targeting its cross-site request forgery (CSRF) protection mechanisms. This issue emerges in versions 3.10.0 through 3.14.63, 3.15.38, 3.16.38, 3.17.34, 3.18.30, and 3.19.18, creating a significant security gap that allows authenticated attackers to bypass critical validation controls. The flaw manifests when an attacker submits an empty string value for the refreshToken parameter while the actual refresh token remains stored in the JWT_REFRESH_TOKEN_COOKIE_NAME cookie, effectively circumventing the CSRF protection layer that should validate all token refresh operations.
The technical implementation of this vulnerability stems from a flawed validation logic in the refresh token mutation handler. When an empty string is provided for the refreshToken parameter, the system incorrectly assumes that no CSRF validation is necessary since the token exists in the cookie, but this assumption is fundamentally flawed. The system fails to properly verify the authenticity of the request context, allowing unauthorized operations to proceed. This bypass occurs because the application's security checks are not properly enforced when the refresh token parameter is empty, despite the presence of a valid token in the cookie storage. The vulnerability directly relates to CWE-352, which defines Cross-Site Request Forgery as a weakness where the application fails to validate that requests originate from legitimate sources, and aligns with ATT&CK technique T1566.001 for credential access through social engineering or token manipulation.
The operational impact of this vulnerability extends beyond simple authentication bypass, potentially enabling attackers to escalate privileges and perform unauthorized actions within the e-commerce platform. An attacker could leverage this weakness to obtain valid access tokens without proper authorization, potentially leading to full account compromise, data exfiltration, or modification of critical e-commerce operations. The vulnerability affects the platform's core authentication and session management capabilities, undermining the integrity of user sessions and potentially allowing for session hijacking attacks. This represents a critical security flaw in the platform's token management system, where the expected CSRF protection mechanism fails to validate request authenticity.
The patched versions of Saleor 3.14.64, 3.15.39, 3.16.39, 3.17.35, 3.18.31, and 3.19.19 address this vulnerability through proper validation of refresh token parameters and CSRF token verification. Security teams should prioritize immediate patching of affected systems to prevent exploitation, as the vulnerability could be leveraged by automated attack tools or sophisticated adversaries. The workaround solution involving modification of the authentication refresh token handler provides a temporary mitigation but introduces a trade-off where the system returns JWT_MISSING_TOKEN instead of JWT_INVALID_TOKEN, which may affect error handling and monitoring systems. Organizations should implement comprehensive monitoring for unusual authentication patterns and token refresh activities, particularly when empty refresh tokens are submitted alongside valid cookie tokens, as this behavior could indicate exploitation attempts. The vulnerability demonstrates the critical importance of proper input validation and CSRF protection in authentication systems, emphasizing the need for robust security controls in web applications that handle sensitive user data and transactions.
