Description

The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. Prior to version 26.05, when a password reset link is visited, the application generates a replacement password in a predictable way and emails it to the account holder. The insufficient entropy allows the password to be brute-forced by an attacker who can approximate the server-side generation time. Exploiting this finding in isolation requires the victim to have triggered the reset themselves and the attacker to infer the server time from network or email metadata. This issue has been patched in version 26.05.
