Integrity High (I:H)
Availability High (A:H)

How to Fix CVE-2017-12262

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2017-12262, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A vulnerability within the firewall configuration of the Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM) could allow an unauthenticated, adjacent attacker to gain privileged access to services only available on the internal network of the device. The vulnerability is due to an incorrect firewall rule on the device. The misconfiguration could allow traffic sent to the public interface of the device to be forwarded to the internal virtual network of the APIC-EM. An attacker that is logically adjacent to the network on which the public interface of the affected APIC-EM resides could leverage this behavior to gain access to services listening on the internal network with elevated privileges. This vulnerability affects appliances or virtual devices running Cisco Application Policy Infrastructure Controller Enterprise Module prior to version 1.5. Cisco Bug IDs: CSCve89638.
