Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Athlon1600/php proxy, 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

PHP-Proxy 5.1.0 allows remote attackers to read local files if the default "pre-installed version" (intended for users who lack shell access to their web server) is used. This occurs because the `aeb067ca0aa9a3193dce3a7264c90187` app_key value from the default config.php is in place, and this value can be easily used to calculate the authorization data needed for local file inclusion.
