How to Fix CVE-2024-35242

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

composer/composer fixed: 2.2.24 
Upgrade composer/composer to 2.2.24
composer/composer fixed: 2.7.7 
Upgrade composer/composer to 2.7.7
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 composer/composer

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-35242, inspect your project dependencies for Composer/composer:

inspect dependencies for composer/composer

Analyze the terminal output to locate any version of Composer/composer in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.24), 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 Composer/composer, 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 `composer install` command running inside a git/hg repository which has specially crafted branch names can lead to command injection. So this requires cloning untrusted repositories. ### Patches 2.2.24 for 2.2 LTS or 2.7.7 for mainline ### Workarounds Avoid cloning potentially compromised repositories.
