Description
Vvveb before version 1.0.8.2 contains an XML external entity (XXE) injection vulnerability in the admin Tools/Import feature that allows authenticated site_admin users to read arbitrary files and modify database records. Attackers can exploit the XML parser configuration in system/import/xml.php to inject file:// or php://filter entity references that are resolved and persisted into the application database, enabling arbitrary file disclosure and administrator password hash overwriting for privilege escalation.
