HighCVSS 7.6Exploitation Probability (EPSS)
Low risk28th percentile - higher than 28% of all known CVEs
Summary
A vulnerability in Data Science Pipelines (DSP) allows an attacker with namespace editor privileges to bypass security hardening by submitting a malicious Argo Workflow through the V1 API path. This allows the API server to create pods with elevated privileges, acting as a 'confused deputy'. Successful exploitation grants the attacker node-root access, enabling arbitrary code execution and full control over the node.
Risk Assessment
An attacker can gain full control over a node, leading to compromise of the entire cluster and potential resource takeover.
Recommendation
Update Data Science Pipelines to a patched version and restrict permissions to create workflows.
Original NVD description (English source)
A flaw was found in Data Science Pipelines (DSP). An attacker with namespace editor privileges can bypass security hardening by submitting a malicious Argo Workflow through the V1 API path. This allows the API server to create pods with elevated privileges, acting as a 'confused deputy' on behalf of the attacker. Successful exploitation grants the attacker node-root access, enabling arbitrary code execution and full control over the underlying node.
