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/symfony

How to Check if You Are Affected

To determine whether your application is affected by CVE-2015-8125, inspect your project dependencies for Symfony/symfony:

inspect dependencies for symfony/symfony

Analyze the terminal output to locate any version of Symfony/symfony in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.35), 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-208: Observable Timing Discrepancy, where two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not. In Symfony/symfony, 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

Symfony 2.3.x before 2.3.35, 2.6.x before 2.6.12, and 2.7.x before 2.7.7 might allow remote attackers to have unspecified impact via a timing attack involving the (1) `Symfony/Component/Security/Http/RememberMe/PersistentTokenBasedRememberMeServices` or (2) `Symfony/Component/Security/Http/Firewall/DigestAuthenticationListener` class in the Symfony Security Component, or (3) legacy CSRF implementation from the `Symfony/Component/Form/Extension/Csrf/CsrfProvider/DefaultCsrfProvider` class in the Symfony Form component.
