Horizon Alert
Summary of the vulnerability and why it matters
IBM API Connect, an API management platform, has a vulnerability that could allow an authenticated user to access or alter data belonging to other users on the system. This issue stems from a missing authorization check.
- Unauthorized access to other tenant data.
- Protects sensitive tenant data and operations.
- Confirm relevance; manage potential data exposure.
Attack Path
How an attacker could exploit the issue
An attacker with existing access to the API Connect management interface could potentially target other tenants' data. This is because the system may not properly check if the authenticated user has permission to access or modify resources belonging to different tenants. If successful, an attacker could read, alter, or delete sensitive information that does not belong to them.
- Authenticated user required.
- Exploits missing tenant authorization.
- Risk of unauthorized data access and modification.
Live Threat
Current exploitation, exposure, and threat context
A remote attacker with administrative privileges could access sensitive information or alter/delete data across different tenants in IBM API Connect when authorization checks are improperly implemented. This could occur when an authenticated user with sufficient permissions exploits the vulnerability to gain unauthorized access to resources belonging to other users or tenants.
- Tenant data and system configuration.
- Exploiting missing authorization checks.
- Unauthorized data access and modification.
Operational Fix
Recommended remediation, mitigation, and detection steps
IBM API Connect's multi-tenancy authorization flaws necessitate a coordinated response. Application owners and platform teams are likely responsible for the API Connect instances, while network and security teams should assess external exposure. The initial practical step involves inventorying all API Connect deployments, confirming their network reachability and business criticality, identifying the accountable owners for each, and then prioritizing remediation efforts based on the assessed risk and potential impact.
- Ownership by App and Platform teams.
- Verify tenant data exposure first.
- Plan remediation around risk.
