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.

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.

The affected products are vulnerable to a cleartext vulnerability that could allow an attacker to obtain user authentication information.

PLC programming software "WindLDR" and Operator Interfaces' Touchscreen Programming Software "WindO/I-NV4" provided by IDEC Corporation store sensitive information in cleartext form (CWE-312). Yuki Meguro of Toinx Co., Ltd. reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.
