Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Craftcms/cms, 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 You are affected if your php.ini configuration has `register_argc_argv` enabled. ### Patches Update to 3.9.14, 4.13.2, or 5.5.2. ### Workarounds If you can't upgrade yet, and `register_argc_argv` is enabled, you can disable it to mitigate the issue.
