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.
