This advisory is a follow-up to the alert titled ICS-ALERT-16-256-02 Schneider Electric ION Power Meter CSRF Vulnerability that was published September 12, 2016, on the NCCIC/ICS-CERT web site.
Independent researcher Karn Ganeshen has identified a cross-site request forgery (CSRF) and no access control vulnerabilities in Schneider Electric’s IONXXXX series power meters. Schneider Electric has produced instructions to mitigate these vulnerabilities.
These vulnerabilities could be exploited remotely.
The following IONXXXX series power meter versions are affected:
An unauthorized user can access the device management portal and make configuration changes.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation.
Schneider Electric’s corporate headquarters is located in Paris, France, and maintains offices in more than 100 countries worldwide.
The affected products, IONXXXX series power meters, provide power and energy monitoring. According to Schneider Electric, these products are deployed across several sectors including Critical Manufacturing, Energy, Water and Wastewater Systems, and others. Schneider Electric estimates that these products are used worldwide.
There is no CSRF Token generated to authenticate the user during a session. Successful exploitation of this vulnerability can allow unauthorized configuration changes to be made and saved.
