概要

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.

NVD の説明

Symphony process is a module for the Symphony PHP framework which executes commands in sub-processes. 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. This issue has been addressed in release versions 5.4.46, 6.4.14, and 7.1.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.
