ABB has an update to mitigate multiple vulnerabilities in its IP Gateway, according to a report with NCCIC.
The remotely exploitable vulnerabilities are an improper authentication, cross-site request forgery, and an unprotected storage of credentials.
Successful exploitation of these vulnerabilities, discovered by Maxim Rupp, could allow attackers to perform actions using administrative privileges.
A building management system, IP Gateway Versions 3.39 and prior suffer from the vulnerabilities. The IP Gateway is available under two brands; ABB and Busch-Jaeger. Busch-Jaeger Elektro GmbH is part of the ABB Group.
In one vulnerability, by accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to access the configuration files and application pages without authentication.
CVE-2017-7931 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.
In addition, the web server does not sufficiently verify that a request was performed by the authenticated user, which may allow an attacker to launch a request impersonating that user.
CVE-2017-7906 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 8.8.
Also, some configuration files contain passwords stored in plain-text, which may allow an attacker to gain unauthorized access.
CVE-2017-7933 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.
The product sees use mainly in the energy sector on a global basis.
No known public exploits specifically target these vulnerabilities. However, an attacker with low skill level could leverage the vulnerabilities.
ABB recommends users apply the update at earliest convenience. The update is available for download at the product page of the Busch-Jaeger catalogue in the Software section.
