CVE-2012-4879

Name of the Vulnerable Software and Affected Versions WAGO I/O System 758 model versions 758-870, 758-874, 758-875, and 758-876

Description The issue concerns default passwords for various accounts on the WAGO I/O System 758 model devices, making it easier for remote attackers to gain login access via a TELNET session. The default passwords are 'wago' for the root and admin accounts, 'user' for the user account, and 'guest' for the guest account.

Recommendations For versions 758-870, 758-874, 758-875, and 758-876, change the default passwords for the root, admin, user, and guest accounts to unique and secure passwords to prevent unauthorized access. As a temporary workaround, consider disabling TELNET sessions until secure passwords are set for all default accounts. Restrict access to the devices to minimize the risk of exploitation by unauthorized users.
