Improper configuration of the Gateway in a model-serving context allows a standard user with low privileges to intercept, read, log, and alter all MaaS model traffic. This includes sensitive information such as access keys, input prompts, and outputs, leading to significant information disclosure and data tampering.\n\n## Affected\n\n- `llm-d < *`\n- `rhoai/odh-rhel9-operator (all versions)`\n- `rhoai/odh-maas-controller-rhel9 (all versions)`\n- `rhoai/odh-kserve-controller-rhel9 (all versions)`\n- `rhoai/odh-model-controller-rhel9 (all versions)`\n- `rhoai/odh-kserve-llmisvc-controller-rhel9 (all versions)`\n- `rhoai/odh-mod-arch-maas-rhel9 (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nYou can restrict Gateway access to some namespaces only. However, it does not prevent someone from an authorized namespace to hijack the traffic of another. Fully locking down access to the MaaS Gateway is a solution, however it defeats the self-service approach of the component.","depth":"twilight","depthScore":49,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
