Credential interception via cleartext login submission
Published Jun 18, 2025 · Updated Jun 20, 2025
Cleartext credential transmission in CloudClassroom-PHP-Project 1.0 allows man-in-the-middle attackers to capture login passwords over HTTP. The loginlinkadmin.php endpoint accepts authentication requests over unencrypted HTTP, placing submitted usernames and passwords in observable request payloads. An attacker with access to the same network can reuse captured administrator credentials for account takeover; code execution requires exploitable administrative functionality in the deployment.
