How to Fix CVE-2024-46977

To remediate this vulnerability, upgrade all affected Openc3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openc3 fixed: 5.19.0

Upgrade openc3 to 5.19.0

openc3 fixed: 5.19.0

pip install openc3>=5.19.0

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 openc3

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-46977, inspect your project dependencies for Openc3:

inspect dependencies for openc3

Analyze the terminal output to locate any version of Openc3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.19.0), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Openc3, 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 path traversal vulnerability inside of `LocalMode`'s `open_local_file` method allows an authenticated user with adequate permissions to download any `.txt` via the `ScreensController#show` on the web server COSMOS is running on (depending on the file permissions). Note: This CVE affects all OpenC3 COSMOS Editions ### Impact This issue may lead to Information Disclosure.
