How to Fix CVE-2024-3955

To remediate this vulnerability, upgrade all affected Cbpi4 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

cbpi4 fixed: 4.4.1.a1 
pip install cbpi4>=4.4.1.a1
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 cbpi4

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-3955, inspect your installed packages using pip:

pip show cbpi4

Analyze the terminal output to locate any version of Cbpi4 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.1.a1), your application is affected.

Note: The pip show cbpi4 command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Cbpi4, 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

URL GET parameter "logtime" utilized within the "downloadlog" function from "cbpi/http_endpoints/http_system.py" is subsequently passed to the "os.system" function in "cbpi/controller/system_controller.py" without prior validation allowing arbitrary code execution. This issue affects CraftBeerPi 4: from 4.0.0.58 (commit 563fae9) before 4.4.1.a1 (commit 57572c7).
