Horizon Alert
Summary of the vulnerability and why it matters
This advisory addresses a critical vulnerability in SAP Commerce Cloud where default, publicly documented credentials for sample OAuth2 clients may remain unchanged. If exploited, an unauthenticated attacker could leverage these known credentials to access APIs, potentially reading and modifying sensitive data, leading to significant impacts on confidentiality and integrity.
- Default credentials can grant unauthorized API access.
- Critical data exposure and modification risks exist.
- Confirm relevance and understand potential data impact.
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker could exploit this vulnerability by leveraging publicly documented sample OAuth2 client credentials found in SAP Commerce Cloud's configuration. If these default credentials are not changed, an attacker can use them to obtain an access token and then call specific APIs. This allows the attacker to read and alter sensitive data.
- Entry condition: Default OAuth2 client credentials are in use.
- Trigger point: Invoking specific APIs with valid credentials.
- Resulting risk: Data can be read and modified.
Live Threat
Current exploitation, exposure, and threat context
SAP Commerce Cloud may retain sample OAuth2 client credentials in its configuration, which are publicly documented. If these credentials are not changed, an unauthenticated attacker could use them to gain access to APIs, potentially reading and altering system data.
- System data and sensitive information at risk.
- Unauthenticated access via known credentials.
- High impact on confidentiality and integrity.
Operational Fix
Recommended remediation, mitigation, and detection steps
SAP Commerce Cloud instances using default OAuth2 client credentials from SAP Help Portal documentation are at risk. An unauthenticated attacker could exploit this to gain access tokens and modify sensitive data. Owners of SAP Commerce Cloud environments should first identify all instances, determine their exposure and criticality, and then assign responsibility for remediation.
- Assign ownership to platform or application teams.
- Verify default OAuth2 credentials are removed.
- Plan remediation based on exposure and criticality.
