CVE-2016-10593

ibapi downloads Resources over HTTP

Affected versions of ibapi insecurely download an executable over an unencrypted HTTP connection.

In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running ibapi.

The application assigns, modifies, tracks, or checks privileges incorrectly, allowing a user to gain elevated access. Typical impact: privilege escalation beyond the intended level.

CVE-2016-10593 has a CVSS score of 8.1 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence

Already deployed Kodem?

No patch is currently available for this vulnerability.

The best mitigation is currently to avoid using this package, using a different package if available.

Alternatively, the risk of exploitation can be reduced by ensuring that this package is not installed while connected to a public network. If the package is installed on a private network, the only people who can exploit this vulnerability are those who have compromised your network or those who have privileged access to your ISP, such as Nation State Actors or Rogue ISP Employees.

1. What is CVE-2016-10593? CVE-2016-10593 is a high-severity improper privilege management vulnerability in ibapi (npm), affecting versions <= 2.6.2. No fixed version is listed yet. The application assigns, modifies, tracks, or checks privileges incorrectly, allowing a user to gain elevated access.
2. How severe is CVE-2016-10593? CVE-2016-10593 has a CVSS score of 8.1 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of ibapi are affected by CVE-2016-10593? ibapi (npm) versions <= 2.6.2 is affected.
4. Is there a fix for CVE-2016-10593? No fixed version is listed for CVE-2016-10593 yet. Monitor the advisory for updates and apply mitigations in the interim.
5. Is CVE-2016-10593 exploitable, and should I be worried? Whether CVE-2016-10593 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.

6. What actually determines whether CVE-2016-10593 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.
7. How do I fix CVE-2016-10593? No fixed version is listed yet. In the interim: Keep the dependency up to date. Apply the principle of least privilege and audit privilege transitions.
