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.





### VULNERABILITY CHARACTERIZATION


# VULNERABILITY OVERVIEW


CROSS-SITE REQUEST FORGERY

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.

CVE-2016-5809 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:HA:H).


IMPROPER ACCESS CONTROL

No authentication is configured by default. An unauthorized user can access the device management portal and make configuration changes.

CVE-2016-5815 has been assigned to this vulnerability. A CVSS v3 base score of 8.1 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:HA:N).






### VULNERABILITY DETAILS


# EXPLOITABILITY

These vulnerabilities could be exploited remotely.


# EXISTENCE OF EXPLOIT

No known public exploits specifically target these vulnerabilities.


# DIFFICULTY

An attacker with a low skill would be able to exploit these vulnerabilities.




### MITIGATION

Schneider Electric's security notice SEVD-2016-256-02, is available at the following location:

http://www2.schneider-electric.com/sites/corporate/en/support/cybersecurity/cybersecurity.page,  

Schneider Electric recommends the following mitigations:

oChange configuration parameter by setting the "Webserver Config Access" register to "Disabled." This register determines whether the user can configure the meter through a browser. Valid entries are Enable or Disable. This register is set to Enable by default.

oChange the "Enable Webserver" register. This register enables or disables the webserver entirely. Values for this register are YES and NO. The web server is enabled by default (the value is set to YES). Some power meters may be revenue locked, which further protects unauthorized meter configuration parameter changes except Owner, Tag1, and Tag2 string registers.
