3.2.9 ALLOCATION OF RESOURCES WITHOUT LIMITS OR THROTTLING CWE-770
The affected application contains a stack exhaustion vulnerability while parsing a specially crafted X_T file. This could allow an attacker to cause denial of service condition.
CVE-2023-38532 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:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H).
Siemens reported these vulnerabilities to CISA.
Siemens released updates for several affected products and recommends updating to the latest versions. Siemens is preparing further updates for Teamcenter Visualization V14.1 and V14.3; fixes are planned for the next patch release:
Siemens identified the following specific workaround/mitigation users can apply to reduce risk:
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 recommendations in the product manuals. 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-407785 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 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 not exploitable remotely. These vulnerabilities have low attack complexity.
