Doc Text:	An authentication vulnerability was found in openstack-ironic. A client with network access to the ironic-api service could bypass OpenStack Identity authentication, and retrieve all information about any node registered with OpenStack Bare Metal. If an unprivileged attacker knew (or was able to guess) the MAC address of a network card belonging to a node, the flaw could be exploited by sending a crafted POST request to the node's /v1/drivers/$DRIVER_NAME/vendor_passthru resource. The response included the node's full details, including management passwords, even if the /etc/ironic/policy.json file was configured to hide passwords in API responses.

Description Adam Mariš 2016-06-14 04:56:05 EDT

A client with network access to the ironic-api service can bypass Keystone authentication and retrieve all information about any Node registered with Ironic, if they know (or are able to guess) the MAC address of a network card belonging to that Node, by sending a crafted POST request to the /v1/drivers/$DRIVER_NAME/vendor_passthru resource.

The response will include the full Node details, including management passwords, even when /etc/ironic/policy.json is configured to hide passwords in API responses.

This vulnerability has been verified in all currently supported branches (liberty, mitaka, master) and traced back to code introduced in commit 3e568fbbbcc5748035c1448a0bdb26306470797c during the Juno development cycle. Therefore, it is likely that both juno and kilo branches (and their releases) are also affected.

Affected versions: >=2014.2, >=4.0.0 <=4.2.4, >=4.3.0 <=5.1.1
