Technical Analysis

This vulnerability (CWE-476) in IBM DataPower Gateway affects multiple versions from 10.5.0.0 up to 11.0.0.2. An attacker could exploit a NULL pointer dereference in the GraphQL variable processing component to trigger a denial of service, causing the affected service to crash or become unavailable. The CVSS 3.1 base score is 5.9, indicating medium severity, with network attack vector, high attack complexity, no privileges required, no user interaction, and impact limited to availability.

Potential Impact

Successful exploitation results in denial of service due to a NULL pointer dereference, impacting availability of the IBM DataPower Gateway. There is no confidentiality or integrity impact reported.

Mitigation Recommendations

No vendor advisory or patch information is provided in the input data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a patch is available, consider limiting exposure of the affected service to untrusted networks and monitor for abnormal service interruptions related to GraphQL processing.
