Pimcore Cookie and Server Variable Logging Vulnerability Allowing Sensitive Data Exposure

Vulnerability

A vulnerability in Pimcore's logging mechanism prior to versions 12.3.1 and 11.5.14 allows sensitive information, including database passwords and session cookie data, to be logged in the 'http_error_log' file. This data can be accessed through the Pimcore backend. The issue arises because the logging function improperly includes POST parameters, cookies, and server variables, which can then be retrieved by users via the 'HTTP Errors' section under 'Search Engine Optimization' in the backend.

Impact

Exploitation of this vulnerability could lead to unauthorized access to sensitive environment variables and cookie information, including database passwords, through the Pimcore backend.

Reproduction

To reproduce this vulnerability, navigate to the 'HTTP Errors' section in the Pimcore backend. Double-click on an entry to view its details, where exposed sensitive data can be found.

Remediation

Users can upgrade to Pimcore versions 12.3.1 or 11.5.14 to address this vulnerability.
