3.2 VULNERABILITY OVERVIEW

3.2.1    IMPROPER PRIVILEGE MANAGEMENT CWE-269

Vulnerabilities in Drive Composer allow a low-privileged user to create and write to a file anywhere on the file system as “system” with arbitrary content when the file does not already exist. The Drive Composer installer file allows a low-privileged user to run a “repair” operation on the product.

CVE-2022-31216 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

3.2.2    IMPROPER PRIVILEGE MANAGEMENT CWE-269

Vulnerabilities in Drive Composer allow a low-privileged user to create and write to a file anywhere on the file system as “system” with arbitrary content when the file does not already exist. The Drive Composer installer file allows a low-privileged user to run a “repair” operation on the product.

CVE-2022-31217 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

3.2.3    IMPROPER PRIVILEGE MANAGEMENT CWE-269

Vulnerabilities in Drive Composer allow a low privileged user to create and write to a file anywhere on the file system as “system” with arbitrary content when the file does not already exist. The Drive Composer installer file allows a low-privileged user to run a “repair” operation on the product.

CVE-2022-31218 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

3.2.4    IMPROPER PRIVILEGE MANAGEMENT CWE-269

Vulnerabilities in Drive Composer allow a low-privileged user to create and write to a file anywhere on the file system as “system” with arbitrary content when the file does not already exist. The Drive Composer installer file allows a low-privileged user to run a “repair” operation on the product.

CVE-2022-31219 has been assigned to this vulnerability. A CVSS v3 base score of 7.3 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H).

3.2.5    IMPROPER PRIVILEGE MANAGEMENT CWE-269

Vulnerabilities in Mint Workbench allow a low-privileged attacker to create and write to a file anywhere on the file system as “system” with arbitrary content when the file does not already exist. The Mint Workbench installer file allows a low-privileged user to run a “repair” operation on the product.

CVE-2022-26057 has been assigned to this vulnerability. A CVSS v3 base score of 6.7 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

4. MITIGATIONS

ABB recommends updating to the latest version of their software:

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

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 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. These vulnerabilities are not exploitable remotely.
