Title: GE Fanuc iFIX Insecure Authentication Multiple Unauthorized Access Vulnerabilities
Severity: HIGH
Description:
GE Fanuc iFIX is an HMI/SCADA client/server application.
Since it handles authentication in an insecure manner, iFIX is prone to multiple vulnerabilities:
1. Clients store usernames and passwords in a local file and are obfuscated with a weak encryption algorithm. Attackers may obtain this file via network sharing. Also, local attackers may access this file directly.
2. Local attackers may alter authentication mechanisms via a specially crafted binary module.
Attackers can exploit these issues to obtain authentication credentials and unauthorized access to vulnerable applications.
GE Fanuc iFIX 5.0 are earlier are vulnerable.
