How to Fix CVE-2024-39717

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-2024-39717, 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-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. 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

The Versa Director GUI provides an option to customize the look and feel of the user interface. This option is only available for a user logged with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin. (Tenant level users do not have this privilege). The “Change Favicon” (Favorite Icon) option can be mis-used to upload a malicious file ending with .png extension to masquerade as image file. This is possible only after a user with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin has successfully authenticated and logged in. Severity: HIGH Exploitation Status: Versa Networks is aware of one confirmed customer reported instance where this vulnerability was exploited because the Firewall guidelines which were published in 2015 & 2017 were not implemented by that customer. This non-implementation resulted in the bad actor being able to exploit this vulnerability without using the GUI. In our testing (not exhaustive, as not all numerical versions of major browsers were tested) the malicious file does not get executed on the client. There are reports of others based on backbone telemetry observations of a 3rd party provider, however these are unconfirmed to date.
