Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary database queries via SQL injection attacks, create a denial-of-service condition, or write arbitrary files to the application’s file system.
Siemens reports that the following server application is affected:
3.2.1 OUT-OF-BOUNDS READ CWE-125
An issue found in SQLite3 v.3.35.4 that could allow a remote attacker to cause a denial of service via the appendvfs.c function.
CVE-2021-31239 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
3.2.2 IMPROPER PRIVILEGE MANAGEMENT CWE-269
Microsoft Windows Defender has an elevation of privilege vulnerability. An attacker who successfully exploited this vulnerability could gain specific limited SYSTEM privileges. This vulnerability could allow an attacker to delete data, which could include data that results in the service being unavailable.
CVE-2022-37971 has been assigned to this vulnerability. A CVSS v3 base score of 7.1 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).
3.2.3 SQL INJECTION CWE-89
The affected application is vulnerable to SQL injection. This could allow an authenticated remote attacker to execute arbitrary SQL queries on the server database and escalate privileges.
CVE-2023-27411 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
3.2.4 SQL INJECTION CWE-89
The affected application is vulnerable to SQL injection. This could allow an unauthenticated remote attacker to execute arbitrary SQL queries on the server database.
CVE-2023-37372 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
3.2.5 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306
The affected application accepts unauthenticated file write messages. An unauthenticated remote attacker could write arbitrary files to the affected application’s file system.
CVE-2023-37373 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N).
National Cyber Security Centre (NCSC) reported these vulnerabilities to Siemens.
Siemens has released an update for RUGGEDCOM CROSSBOW and recommends updating to the latest version:
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 the Siemens’ operational guidelines for industrial security and following product manual recommendations.
Additional information on Siemens industrial security can be found on the Siemens industrial security webpage.
For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT.
For more information, see the associated Siemens security advisory SSA-472630 in HTML and CSAF.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
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.
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. These vulnerabilities are exploitable remotely. These vulnerabilities have low attack complexity.
