3.2 VULNERABILITY OVERVIEW

3.2.1    IMPROPER CONTROL OF GENERATION OF CODE ('CODE INJECTION') CWE-94

By injecting code into specific configuration options for OpenVPN, an attacker could execute arbitrary code with elevated privileges on affected Siemens RUGGEDCOM and SCALANCE devices.

CVE-2022-34821 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been calculated. the CVSS vector string is (CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H)

3.2.2    USE OF A BROKEN OR RISKY CRYPTOGRAPHIC ALGORITHM CWE-327

Affected Siemens RUGGEDCOM and SCALANCE devices use a weak encryption scheme to encrypt the debug zip file. This could allow an authenticated attacker to decrypt the contents of the file and retrieve debug information about the system.

CVE-2022-46140 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated. the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

3.2.3    STORING PASSWORDS IN A RECOVERABLE FORMAT CWE-257

Affected Siemens RUGGEDCOM and SCALANCE devices store command line interface (CLI) user passwords encrypted in flash memory. Attackers with physical access to the device could retrieve the file and decrypt CLI user passwords.

CVE-2022-46142 has been assigned to this vulnerability. A CVSS v3 base score of 5.7 has been calculated. the CVSS vector string is (CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L)

3.2.4    IMPROPER VALIDATION OF SPECIFIED QUANTITY IN INPUT CWE-1284

Affected Siemens RUGGEDCOM and SCALANCE devices do not check the TFTP blocksize correctly. This could allow an authenticated attacker to read from an uninitialized buffer potentially containing previously allocated data.

CVE-2022-46143 has been assigned to this vulnerability. A CVSS v3 base score of 2.7 has been calculated. the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N)

3.2.5    IMPROPER CONTROL OF A RESOURCE THROUGH ITS LIFETIME CWE-664

Affected Siemens SCALANCE devices do not properly process CLI commands after a user forcefully quits the secure shell (SSH) connection. This could allow an authenticated attacker to make the CLI via SSH or serial interface irresponsive.

CVE-2022-46144 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated. the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

3.4 RESEARCHER

Siemens reported these vulnerabilities to CISA.

4. MITIGATIONS

Siemens recommends updating to the latest version of its software where available:

As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens’ operational guidelines for industrial security and following recommendations in the product manuals.

Additional information on industrial security by Siemens can be found on the Siemens industrial security webpage 

For more information, see the associated Siemens security advisory SSA-413565 in HTML and CSAF.

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.
