As of January 10, 2023, CISA will no longer be updating ICS security advisories for Siemens product vulnerabilities beyond the initial advisory. For the most up-to-date information on vulnerabilities in this advisory, please see Siemens’ ProductCERT Security Advisories (CERT Services | Services | Siemens Global).
Successful exploitation of these vulnerabilities could allow an authenticated local attacker to execute arbitrary code with system privileges.
Siemens reports that the following versions of SINEMA Remote Connect management platform are affected:
The system service of affected applications is vulnerable to command injection due to missing server side input sanitation when loading VPN configurations. This could allow an authenticated local attacker to execute arbitrary code with system privileges.
CVE-2024-39567 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2024-39567. A base score of 8.5 has been calculated; the CVSS vector string is (CVSS4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
The system service of affected applications is vulnerable to command injection due to missing server side input sanitation when loading proxy configurations. This could allow an authenticated local attacker to execute arbitrary code with system privileges.
CVE-2024-39568 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2024-39568. A base score of 8.5 has been calculated; the CVSS vector string is (CVSS4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
The system service of affected applications is vulnerable to command injection due to missing server side input sanitation when loading VPN configurations. This could allow an administrative remote attacker running a corresponding SINEMA Remote Connect Server to execute arbitrary code with system privileges on the client system.
CVE-2024-39569 has been assigned to this vulnerability. A CVSS v3 base score of 6.6 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2024-39569. A base score of 7.5 has been calculated; the CVSS vector string is (CVSS4.0/AV:N/AC:H/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
Siemens reported these vulnerabilities to CISA.
Siemens has released a new version for SINEMA Remote Connect Client and recommends updating to version (V3.2 HF1 or later.
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-868282 in HTML and CSAF.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. 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 on cisa.gov. 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.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov 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 exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
