CVE-2025-24875 in Commerce
Summary
by MITRE • 02/11/2025
SAP Commerce, by default, sets certain cookies with the SameSite attribute configured to None (SameSite=None). This includes authentication cookies utilized in SAP Commerce Backoffice. Applying this setting reduces defense in depth against CSRF and may lead to future compatibility issues.

SAP Commerce platforms configured with default settings exhibit a significant security weakness through the improper implementation of SameSite cookie attributes. The vulnerability manifests when authentication cookies used within the SAP Commerce Backoffice environment are explicitly set with SameSite=None, a configuration that fundamentally undermines the intended security posture of the application. This flaw directly violates established security best practices and creates exploitable conditions for cross-site request forgery attacks. The SameSite cookie attribute serves as a critical browser-based security mechanism designed to prevent unauthorized cross-site requests by controlling when cookies are sent with cross-site requests. When set to None, the cookie becomes susceptible to being transmitted across different origins, effectively neutralizing the protection that SameSite is meant to provide. This misconfiguration represents a clear violation of the principle of defense in depth, where multiple layers of security controls should work together to protect systems from various attack vectors. The vulnerability affects the authentication mechanisms within SAP Commerce Backoffice, which is a critical administrative interface used for managing commerce operations and sensitive business data. The impact extends beyond simple CSRF protection as it also introduces compatibility risks with modern browser security policies that are increasingly strict about SameSite=None usage, particularly when cookies are used in cross-site contexts.
The technical implementation flaw stems from SAP Commerce's default configuration where authentication cookies are explicitly configured with SameSite=None rather than utilizing the more secure default behavior or appropriate SameSite values such as Lax or Strict. This configuration choice creates a dangerous exposure because authentication cookies inherently contain sensitive session information that, if compromised through CSRF attacks, could allow unauthorized access to administrative functions. The vulnerability specifically impacts the SAP Commerce Backoffice environment where users perform critical administrative tasks including product management, order processing, and system configuration changes. From an operational perspective, this flaw exposes organizations to potential unauthorized access and privilege escalation attacks that could result in significant data breaches and system compromise. The risk is particularly elevated in environments where users may be targeted through social engineering or phishing campaigns that could leverage the CSRF vulnerability to execute unauthorized administrative actions. Security professionals should note that this configuration issue aligns with CWE-166, which addresses the use of insecure cookie attributes in web applications, and represents a specific instance of improper security configuration that undermines the fundamental security controls of the application.
Organizations deploying SAP Commerce systems must implement immediate remediation measures to address this vulnerability by modifying the cookie configuration to use appropriate SameSite values that align with the security requirements of the application. The recommended approach involves setting authentication cookies to SameSite=Lax or SameSite=Strict depending on the specific use case and application requirements, ensuring that cookies are not transmitted in cross-site requests unless explicitly required. This remediation strategy directly addresses the ATT&CK technique T1190, which involves exploiting web application vulnerabilities to gain unauthorized access, by strengthening the cookie-based authentication controls. System administrators should also consider implementing additional monitoring and logging mechanisms to detect potential CSRF attempts that may exploit this vulnerability. The mitigation process requires careful evaluation of the application's cross-site request requirements to ensure that the chosen SameSite value does not inadvertently break legitimate functionality. Organizations should also review their browser compatibility requirements, as modern browsers are increasingly enforcing stricter policies around SameSite=None usage, particularly for cookies that are used in cross-site contexts. The vulnerability represents a critical security concern that requires immediate attention from security teams and system administrators to maintain the integrity and confidentiality of SAP Commerce environments. Regular security assessments and configuration reviews should be implemented to prevent similar misconfigurations from occurring in other components of the SAP Commerce platform or related systems.
