Symfony vulnerable to command execution hijack on Windows with Process class
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 for branch 5.4.
Credits
We would like to thank Jordi Boggiano for reporting the issue and Nicolas Grekas for providing the fix.
