How to Check if You Are Affected
To determine whether your application is affected by CVE-2017-16790, 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 3.2.14), 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. 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.

When a form is submitted by the user, the request handler classes of the Form component merge POST data and uploaded files data into one array. This big array forms the data that are then bound to the form. At this stage there is no difference anymore between submitted POST data and uploaded files. A user can send a crafted HTTP request where the value of a \"FileType\" is sent as normal POST data that could be interpreted as a local file path on the server-side (for example, \"file:///etc/passwd\"). If the application did not perform any additional checks about the value submitted to the \"FileType\", the contents of the given file on the server could have been exposed to the attacker.",
