Background
OpenStack Ironic Inspector (aka ironic-inspector or ironic-discoverd) is a component of the OpenStack project that provides hardware introspection capabilities. It is used to discover and inspect bare metal nodes in an OpenStack environment. The package allows users to gather information about the hardware properties of these nodes, such as MAC addresses, IP addresses, and other relevant details. However, when debug mode is enabled, a vulnerability exists that could allow remote attackers to access the Flask console and execute arbitrary Python code by triggering an error.
Vulnerability Detail
The vulnerability (CVE-2015-5306) in OpenStack Ironic Inspector arises when debug mode is enabled. In this mode, an attacker can exploit an error to gain access to the Flask console, which provides a Python shell. By executing arbitrary Python code through this console, the attacker can potentially compromise the entire system. This vulnerability poses a significant risk to the confidentiality, integrity, and availability of the OpenStack environment.
How To Fix
Latest published version: 12.5.0 as of 23 Oct 2026
pip install --upgrade "ironic-inspector==12.5.0"Upgrading to it may include breaking changes; the version below is the minimum fixed release for this vulnerability.
If you need the minimum change
2.3.0
This is the first release that contains the fix.
pip install --upgrade "ironic-inspector==2.3.0"Tip — Not sure which version your app runs? Vulert can match this fix to it. Scan free →
Workaround
If upgrading to the latest version is not immediately feasible, a temporary workaround can be implemented by disabling the debug mode in the ironic-inspector configuration. By setting the 'debug' option to 'False' in the configuration file, the vulnerable functionality can be effectively disabled. However, this workaround should only be considered as a temporary measure, and upgrading to the latest version is strongly recommended.
Conclusion
The vulnerability in OpenStack Ironic Inspector (CVE-2015-5306) poses a significant risk to the security of OpenStack environments. It allows remote attackers to execute arbitrary Python code by accessing the Flask console. To mitigate this risk, it is crucial to upgrade to the latest version of the ironic-inspector package (2.3.0 or later) or apply the temporary workaround of disabling the debug mode.
