What is CVE-2015-7713?

CVE-2015-7713 is a medium-severity security vulnerability in nova (pip), affecting versions < 2014.2.4. It is fixed in 2014.2.4, 2015.1.2.

Which versions of nova are affected by CVE-2015-7713?

nova (pip) versions < 2014.2.4 is affected.

Is there a fix for CVE-2015-7713?

Yes. CVE-2015-7713 is fixed in 2014.2.4, 2015.1.2. Upgrade to this version or later.

Is CVE-2015-7713 exploitable, and should I be worried?

Whether CVE-2015-7713 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2015-7713 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

How do I fix CVE-2015-7713?

Upgrade: nova to 2014.2.4 or later, nova to 2015.1.2 or later.

Summary

OpenStack Compute (Nova) allows remote attackers to bypass intended restriction

OpenStack Compute (Nova) before 2014.2.4 (juno) and 2015.1.x before 2015.1.2 (kilo) do not properly apply security group changes, which allows remote attackers to bypass intended restriction by leveraging an instance that was running when the change was made.

Impact

Affected versions

nova (< 2014.2.4) nova (>= 2015.1.0, < 2015.1.2)

Security releases

nova → 2014.2.4 (pip) nova → 2015.1.2 (pip)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
