How to Fix CVE-2024-23637

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

OctoPrint fixed: 1.10.0rc1 
pip install OctoPrint>=1.10.0rc1
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 OctoPrint

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-23637, inspect your installed packages using pip:

pip show OctoPrint

Analyze the terminal output to locate any version of OctoPrint in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.10.0rc1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In OctoPrint, 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 OctoPrint versions up until and including 1.9.3 contain a vulnerability that allows malicious admins to change the password of other admin accounts, including their own, without having to repeat their password. An attacker who managed to hijack an admin account might use this to lock out actual admins from their OctoPrint instance. ### Patches The vulnerability will be patched in version 1.10.0. ### Workarounds OctoPrint administrators are strongly advised to thoroughly vet who has admin access to their installation. ### Credits This vulnerability was discovered and responsibly disclosed to OctoPrint by Timothy "TK" Ruppert.
