How to Fix CVE-2022-2922

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

DotNetNuke.Core fixed: 9.11.0 
Upgrade DotNetNuke.Core to 9.11.0
DotNetNuke.Web fixed: 9.11.0 
Upgrade DotNetNuke.Web to 9.11.0
Verify Direct and Transitive Dependencies

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

inspect dependencies for DotNetNuke.Core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-2922, inspect your project dependencies for DotNetNuke.Core:

inspect dependencies for DotNetNuke.Core

Analyze the terminal output to locate any version of DotNetNuke.Core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.11.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-23: Relative Path Traversal, where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. In DotNetNuke.Core, 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

DNN (GitHub repository dnnsoftware/dnn.platform) prior to 9.11.0 is vulnerable to Relative Path Traversal. Version 9.11.0 contains a patch for this issue.
