Credential theft via attacker-controlled login destination
Published Mar 9, 2022 · Updated Sep 16, 2024
Credential theft in the OpenSUSE Open Build Service login proxy allows remote attackers to capture cleartext user passwords. The login-proxy-scripts component accepts an attacker-controlled destination for an authentic-looking login form and forwards entered credentials without restricting the destination to a trusted domain. Exploitation requires a user to submit credentials through the presented form; it exposes the password and permits unauthorized use of the compromised account.
