CVE-2020-37135Public exploitNetwork attack vector

Administrative access via hard-coded login credentials

Published Feb 6, 2026 · Updated Feb 6, 2026

Authentication bypass in Amssplus AMSS++ 4.7 allows remote attackers to gain administrative access through hard-coded login credentials. The web login at innoobec/index.php accepts the shared admin password 1234, granting an administrative session instead of requiring an installation-specific secret. Network access to the login page and knowledge of the published credential are sufficient; the resulting account exposes administrative data and functions.
