How to Fix CVE-2023-32303

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

planet fixed: 2.0.1 
pip install planet>=2.0.1
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 planet

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-32303, inspect your installed packages using pip:

pip show planet

Analyze the terminal output to locate any version of Planet in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. In Planet, 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

### Impact The secret file stores the user's Planet API authentication information. It should only be accessible by the user, but its permissions allowed the user's group and non-group to read the file as well. ### Validation Check the permissions on the secret file with `ls -l ~/.planet.json` and ensure that they read as `-rw-------` ### Patches [d71415a8](https://github.com/planetlabs/planet-client-python/commit/d71415a83119c5e89d7b80d5f940d162376ee3b7) ### Workarounds Set the secret file permissions to only user read/write by hand: ``` chmod 600 ~/.planet.json ```
