CVSS v3 9.8
ATTENTION: Exploitable remotely/low skill level to exploit.
Vendor: Geutebrück
Equipment: IP Cameras
Vulnerabilities: Improper Authentication, SQL Injection, Cross-Site Request
Forgery, Improper Access Control, Server-Side Request Forgery, Cross-site
Scripting
AFFECTED PRODUCTS
Geutebrück reports that the vulnerabilities affect the following IP cameras:
G-Cam/EFD-2250 (part n° 5.02024) firmware version 1.12.0.4, and
Topline TopFD-2125 (part n° 5.02820) firmware version 3.15.1
IMPACT
Successful exploitation of these vulnerabilities could lead to proxy network
scans, access to a database, adding an unauthorized user to the system, full
configuration download including passwords, and remote code execution.
MITIGATION
Geutebrück recommends G-Cam/EFD-2250 users download and update to the newest
firmware version, 1.12.0.19, by registering for a new WebClub account, or by
logging into an existing account at the following location:
https://www.geutebrueck.com//en_EN/login.html (link is external)
Topline users can visit the previous link for workaround advice and contact
information regarding the vulnerabilities associated with the device.
NCCIC recommends users take defensive measures to minimize the risk of
exploitation of these vulnerabilities. Specifically, users should:
Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
When remote access is required, use secure methods, such as virtual private
networks (VPNs), recognizing that VPNs may have vulnerabilities and should
be updated to the most current version available. Also recognize that VPN
is only as secure as the connected devices.
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
in the NCCIC Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber
Intrusion Detection and Mitigation Strategies, that is available for download
from the ICS-CERT website.
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.
No known public exploits specifically target these vulnerabilities.
