CVSS v3 9.8
ATTENTION: Exploitable remotely/low skill level to exploit
Vendor: ABB
**Equipment:**IP Gateway
Vulnerabilities: Improper Authentication, Cross-site Request Forgery, Unprotected Storage of Credentials
Successful exploitation of these vulnerabilities could allow attackers to perform actions using administrative privileges.
The following versions of IP Gateway, a building management system, are affected. The IP Gateway is available under two brands; ABB and Busch-Jaeger. Busch-Jaeger Elektro GmbH is part of the ABB Group.
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 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
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 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
Some configuration files contain passwords stored in plain-text, which may allow an attacker to gain unauthorized access.
CVE-2017-7933 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

NCCIC recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
NCCIC also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS-CERT website in the Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
NCCIC also recommends that users take the following measures to protect themselves from social engineering attacks:
No known public exploits specifically target these vulnerabilities.
