Summary
SSA-238730: Out-of-Bounds Write Vulnerabilities in SITOP UPS1600 before V2.5.4
Notes
Summary
Multiple out-of-bounds vulnerabilities in third-party components are affecting SITOP UPS1600 before V2.5.4. Attackers could exploit these vulnerabilities and cause limited impact in the affected systems.
Siemens has released new versions for the affected products and recommends to update to the latest versions.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download:
https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.
Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

"text": "In ntp existieren mehrere Schwachstellen aufgrund von \"out of bounds\" Speicherzugriffen. Betroffen sind die Komponenten in \"libntp/mstolfp.c\" aus \"libntp\" und \"praecis_parse\" in \"ntpd/refclock_palisade.c\". Nach neueren Recherchen ist ein Remote-Angriff auf einen laufenden ntpd unwahrscheinlich, da die Funktion mstolfp(), die die ersten vier CVE\u2019s (CVE-2023-26551, CVE-2023-26552, CVE-2023-26553, CVE-2023-26554) betrifft, zwar in libntp/mstolfp.c definiert, aber von ntpd selbst nicht aufgerufen wird. Verwendet wird die Funktion lediglich im Hilfsprogramm ntpq, welches der Administrator aufrufen kann, um Status-Informationen von ntpd abzurufen und anzuzeigen. Folglich erfordert der Angriff eine lokale Interaktion eines Administrators und die Nutzung eines vom Angreifer kontrollierten NTP Servers. Die letzte CVE (CVE-2023-26555) bezieht sich auf einen Treiber f\u00fcr bestimmte GPS Empf\u00e4nger, die h\u00f6chstwahrscheinlich nur noch vereinzelt in Gebrauch sind. Eine Ausnutzung ist auch hier sehr unwahrscheinlich. Unsere Bewertung dieser Schwachstellen haben wir deshalb deutlich verringert."

Summary
Siemens SITOP UPS1600
Notes
Summary
Multiple out-of-bounds vulnerabilities in third-party components are affecting SITOP UPS1600 before V2.5.4. Attackers could exploit these vulnerabilities and cause limited impact in the affected systems.
Siemens has released new versions for the affected products and recommends to update to the latest versions.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download:
https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.
Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability.
Recommended Practices
Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.
Recommended Practices
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
Recommended Practices
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices.
Recommended Practices
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
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.
Recommended Practices
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.
Recommended Practices
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
