RCE in Wirtualna Uczelnia

Assigner: CERT-PL
Reserved: 24.10.2025 Published: 27.11.2025 Updated: 28.11.2025

The application contains an insecure 'redirectToUrl' mechanism that incorrectly processes the value of the 'redirectUrlParameter' parameter. The application interprets the entered string of characters as a Java expression, allowing an unauthenticated attacer to perform arbitrary code execution. This issue was fixed in version wu#2016.1.5513#0#20251014_113353
