Why It Matters

An issue was discovered in OpenStack ironic-python-agent 1.0.0 through 11.5.0. Ironic Python Agent (IPA) sometimes executes grub-install from within a chroot of the deployed partition image, leading to code execution in the case of a malicious image.

Suggested hunting (rule-based inference)

SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.

Matched command-injection (CWE-78)

Exposure

  1. Identify installations of the affected product and compare versions with the advisory.Telemetry: DeviceTvmSoftwareVulnerabilities · A weakness class does not establish local exposure. · Rule command-injection

Exploitation evidence

  1. Review command interpreters spawned by the affected service or application.Telemetry: DeviceProcessEvents · Unexpected process lineage can support command-injection hunting. · Rule command-injection

Response

  1. Confirm the vendor mitigation or fixed version on affected assets.Telemetry: DeviceTvmSoftwareVulnerabilities · Inventory checks can verify remediation. · Rule command-injection
