Technical details
A privilege escalation vulnerability exists in Vvveb versions prior to 1.0.8.1 due to improper input validation in the admin user profile save endpoint. The application fails to restrict the modification of sensitive object attributes (CWE-915), allowing an authenticated user to inject a 'role_id=1' parameter into their profile update request. By doing so, a low-privileged user can escalate their privileges to Super Administrator. Once escalated, the attacker can leverage administrative features, such as plugin uploads, to achieve remote code execution (RCE) on the server. The issue is addressed in version 1.0.8.1.
