How to Fix CVE-2023-40017

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

geonode fixed: 4.2.0 
pip install geonode>=4.2.0
Verify Direct and Transitive Dependencies

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

pip show geonode

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-40017, inspect your installed packages using pip:

pip show geonode

Analyze the terminal output to locate any version of Geonode in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.2.0), your application is affected.

Note: The pip show geonode command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Geonode, 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

### Summary A server side request forgery vuln was found within geonode when testing on a bug bounty program. Server side request forgery allows a user to request information on the internal service/services. ### Details The endpoint /proxy/?url= does not properly protect against SSRF. when using the following format you can request internal hosts and display data. /proxy/?url=http://169.254.169.254\@whitelistedIPhere. This will state wether the AWS internal IP is alive. If you get a 404, the host is alive. A non alive host will not display a response. To display metadata, use a hashfrag on the url /proxy/?url=http://169.254.169.254\@#whitelisteddomain.com or try /proxy/?url=http://169.254.169.254\@%23whitelisteddomain.com ### Impact Port scan internal hosts, and request information from internal hosts.
