How to Fix CVE-2021-41028

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-2021-41028, 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-798: Use of Hard-coded Credentials, where the product contains hard-coded credentials, such as a password or cryptographic key. 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 combination of a use of hard-coded cryptographic key vulnerability [CWE-321] in FortiClientEMS 7.0.1 and below, 6.4.6 and below and an improper certificate validation vulnerability [CWE-297] in FortiClientWindows, FortiClientLinux and FortiClientMac 7.0.1 and below, 6.4.6 and below may allow an unauthenticated and network adjacent attacker to perform a man-in-the-middle attack between the EMS and the FCT via the telemetry protocol.
