Summary
Pimcore ENV Variables and Cookie Informations are exposed in http_error_log
Details

Summary

The http_error_log file stores the $_COOKIE and $_SERVER variables, which means sensitive information such as database passwords, cookie session data, and other details can be accessed or recovered through the Pimcore backend.

Details

It’s better to remove both lines, as this information makes little sense in this context anyway.

PoC

In the Pimcore backend, navigate to "Search Engine Optimization" and click on "HTTP Errors." Double-click on an entry to view its details. Here, you may find sensitive data exposed.

Impact

Pimcore backend users can access sensitive environment variables, potentially exposing critical information.

Severity ?
8.6 (High)
