TITLE

Schneider Electric U.motion Builder Software Vulnerabilities related to the use of hard-coded credentials

Trust: 0.8

sources: JVNDB: JVNDB-2017-008207

DESCRIPTION

An authentication bypass vulnerability exists in Schneider Electric's U.motion Builder software versions 1.2.1 and prior in which the system contains a hard-coded valid session. An attacker can use that session ID as part of the HTTP cookie of a web request, resulting in authentication bypass. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of session management. The application has a hard-coded static session ID. U.motion Builder is a generator product from Schneider Electric, France. An SQL-injection vulnerability 2. A directory-traversal vulnerability 3. An information-disclosure vulnerability 5. A local code-execution vulnerability 6. A local denial-of-Service vulnerability 7. An information-disclosure vulnerability Exploiting these issues could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, bypass authentication mechanism, obtain sensitive information, execute arbitrary code and perform unauthorized actions. Failed exploits can result in a denial-of-service condition

title:	This vulnerability is being disclosed publicly without a patch in accordance with the ZDI 120 day deadline.03/29/2016 - ZDI disclosed the vulnerability reports to ICS-CERT (with an expected 'due date' of 07/27/16).03/29/2016 - ICS-CERT acknowledged that they received them and "sent them on to our contacts at Schneider Electric, and will keep you informed of their progress. We are tracking these issues as ICS-VU-291195."08/24/2016 - ZDI sent a follow-up inquiry to ICS-CERT requesting the status.09/08/2016 - ICS-CERT replied requesting more information on one vulnerability report, but said of the others, "they have successfully validated the rest of the vulnerability reports. Unfortunately, they don't 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. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.	url:	http://technet.microsoft.com/en-us/library/cc725770%28WS.10%29.aspx	Trust: 0.7
