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 attacker to read and modify data passed over the connection between legitimate clients and the affected product or brute force user passwords.
The following versions of Siemens Location Intelligence, a web-based application software, are affected:
The web server of affected products is configured to support weak ciphers by default. This could allow an unauthenticated attacker in an on-path position to to read and modify any data passed over the connection between legitimate clients and the affected device.
CVE-2024-41681 has been assigned to this vulnerability. A CVSS v3.1 base score of 6.7 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:R/S:U/C:L/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2024-41681. A base score of 6.0 has been calculated; the CVSS vector string is (CVSS4.0/AV:A/AC:H/AT:P/PR:N/UI:P/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N).
Affected products do not properly enforce restriction of excessive authentication attempts. This could allow an unauthenticated remote attacker to conduct brute force attacks against legitimate user passwords.
CVE-2024-41682 has been assigned to this vulnerability. A CVSS v3.1 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
A CVSS v4 score has also been calculated for CVE-2024-41682. A base score of 6.9 has been calculated; the CVSS vector string is (CVSS4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N).
Affected products do not properly enforce a strong user password policy. This could facilitate a brute force attack against legitimate user passwords.
CVE-2024-41683 has been assigned to this vulnerability. A CVSS v3.1 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
A CVSS v4 score has also been calculated for CVE-2024-41683. A base score of 6.9 has been calculated; the CVSS vector string is (CVSS4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N).
Siemens reported these vulnerabilities to CISA.
Siemens recommends users update to the latest version:
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-720392 in HTML and CSAF.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:
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/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.
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/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.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
