Sources and claim methodology

  • GitHub security advisorygithub.com
  • Source referenceprestashop.com
Upstream source description

PrestaShop contains an authenticated PHP code injection vulnerability in the back-office Performance debug-mode configuration. A back-office user with permission to modify debug settings can supply a crafted `debug_cookie_name` or `debug_cookie_value` that is written without sufficient escaping into a PHP configuration file. When PrestaShop subsequently loads the generated file, the injected PHP code is executed with the privileges of the web-server process.
