Idec: Security Vulnerabilities
Cleartext storage of sensitive information vulnerability exists in WindLDR and WindO/I-NV4. If this vulnerability is exploited, an attacker who obtained the product's project file may obtain user credentials of the PLC or Operator Interfaces. As a result, an attacker may be able to manipulate and/or suspend the PLC and Operator Interfaces by accessing or hijacking them.
