Vulnerability from variot
The vulnerability exists within processing of nfcserver.php in Schneider Electric U.motion Builder software versions prior to v1.3.4. The underlying SQLite database query is subject to SQL injection on the sessionid input parameter. Authentication is not required to exploit this vulnerability.The specific flaw exists within processing of nfcserver.php, which is exposed on the web service with no authentication. A remote attacker can leverage this vulnerability to execute arbitrary commands against the database

Unfortunately, they don\u0027t expect to have a patch ready until the end of this year.\" ICS-CERT suggested they would work with the vendor to try to bring this in.09/19/2016 - ZDI sent a follow-up inquiry to ICS-CERT asking if the vendor was anywhere closer.10/11/2016 - ZDI sent a follow-up inquiry to ICS-CERT asking if the vendor was anywhere closer and stressed potential 0-day.12/14/2016 - ZDI sent a follow-up inquiry to ICS-CERT requesting the status.06/02/2017 - ZDI sent a follow-up inquiry to ICS-CERT requesting the status.-- Mitigation:Given the nature of the vulnerability, the only salient mitigation strategy is to restrict interaction with the service to trusted machines. Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting.
