AWS credential disclosure via unauthenticated login_up.php requests

Published Jul 3, 2025 · Updated Jul 3, 2025

Information disclosure in Plesk Obsidian 18.0.69 allows remote attackers to obtain AWS credentials through /login_up.php. The login_up.php handler returns an AWS accessKeyId, secretAccessKey, region, and endpoint without verifying authentication. Network access to the Plesk login interface is sufficient; the reported consequence is disclosure of those AWS configuration values.
