3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following versions of Cognex 3D-A1000 Dimensioning System, an industrial smart camera, are affected:

• Cognex 3D-A1000 Dimensioning System: Firmware Version: 1.0.3 (3354) and prior

3.2 VULNERABILITY OVERVIEW

3.2.1    MISSING AUTHENTICATION FOR CRITICAL FUNCITON CWE-306

The affected product allows unauthorized users to change the operator account password via webserver commands by monitoring web socket communications from an unauthenticated session. This could allow an attacker to escalate privileges to match those of the compromised account.

CVE-2022-1368 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).

3.2.2    IMPROPER OUTPUT NEUTRALIZATION FOR LOGS CWE-117

The affected product allows an attacker to create false logs that show the password as having been changed when it is not, complicating forensics.

CVE-2022-1522 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

3.2.3    CLIENT-SIDE ENFORCEMENT OF SERVER-SIDE SECURITY CWE-602

Attackers could bypass web access controls by inspecting and modifying the source code of password protected web elements.

CVE-2022-1525 has been assigned to this vulnerability. A CVSS v3 base score of 9.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

4. MITIGATIONS

Cognex has reportedly fixed these issues in release 1.2 PR2. For more information, users should contact Cognex support (login required).

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability these vulnerabilities. Specifically, users should:

• Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
• Locate control system networks and remote devices behind firewalls and isolate them from business networks.
• When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as its connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best 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 webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

No known public exploits specifically target these vulnerabilities.
