How to Fix CVE-2024-51736

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

symfony/process fixed: 5.4.46 
Upgrade symfony/process to 5.4.46
symfony/process fixed: 6.4.14 
Upgrade symfony/process to 6.4.14
symfony/process fixed: 7.1.7 
Upgrade symfony/process to 7.1.7
symfony/symfony fixed: 5.4.46 
Upgrade symfony/symfony to 5.4.46
symfony/symfony fixed: 6.4.14 
Upgrade symfony/symfony to 6.4.14
symfony/symfony fixed: 7.1.7 
Upgrade symfony/symfony to 7.1.7
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 symfony/process

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-51736, inspect your project dependencies for Symfony/process:

inspect dependencies for symfony/process

Analyze the terminal output to locate any version of Symfony/process in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.4.46), 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-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In Symfony/process, 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

### Description On Windows, when an executable file named `cmd.exe` is located in the current working directory it will be called by the `Process` class when preparing command arguments, leading to possible hijacking. ### Resolution The `Process` class now uses the absolute path to `cmd.exe`. The patch for this issue is available [here](https://github.com/symfony/symfony/commit/18ecd03eda3917fdf901a48e72518f911c64a1c9) for branch 5.4. ### Credits We would like to thank Jordi Boggiano for reporting the issue and Nicolas Grekas for providing the fix.
