CVE-2019-10141 Explained : Impact and Mitigation

A security issue has been detected in all versions of openstack-ironic-inspector except for 5.0.2, 6.0.3, 7.2.4, 8.0.3, and 8.2.1. The vulnerability involves a SQL-injection vulnerability found in the node_cache.find_node() function of openstack-ironic-inspector. This particular function executes a SQL query using unfiltered data obtained from a server that reports inspection results through a POST request sent to the /v1/continue endpoint. Since the API lacks authentication, an attacker with network access to the system running ironic-inspector could potentially exploit this flaw. It is important to note that given how ironic-inspector utilizes the query results, it is unlikely that any data could be accessed. However, an attacker can manipulate the data to cause a denial of service.
