Vulnerability from variot

Stack-based buffer overflow in the NTP time-server interface on Meinberg IMS-LANTIME M3000, IMS-LANTIME M1000, IMS-LANTIME M500, LANTIME M900, LANTIME M600, LANTIME M400, LANTIME M300, LANTIME M200, LANTIME M100, SyncFire 1100, and LCES devices with firmware before 6.20.004 allows remote attackers to obtain sensitive information, modify data, or cause a denial of service via a crafted parameter in a POST request. Meinberg NTP Time Server is prone to multiple privilege-escalation and stack-based buffer-overflow vulnerabilities. Remote attackers can exploit these issues to execute arbitrary code in the context of the application or gain elevated privileges. Other attacks are also possible. The following products are affected : Meinberg IMS-LANTIME M3000 Version 6.0 and prior Meinberg IMS-LANTIME M1000 Version 6.0 and prior Meinberg IMS-LANTIME M500 Version 6.0 and prior Meinberg LANTIME M900 Version 6.0 and prior Meinberg LANTIME M600 Version 6.0 and prior Meinberg LANTIME M400 Version 6.0 and prior Meinberg LANTIME M300 Version 6.0 and prior Meinberg LANTIME M200 Version 6.0 and prior Meinberg LANTIME M100 Version 6.0 and prior Meinberg SyncFire 1100 Version 6.0 and prior Meinberg LCES Version 6.0 and prior. Meinberg IMS-LANTIME M3000 etc. are all NTP time servers of German Meinberg company. #!/usr/bin/python

CISA Disclaimer

This CSAF advisory was extracted from unstructured data and may contain inaccuracies. If you notice any errors, please reach out to the designated contact at CISA CSAF: central@cisa.dhs.gov

Recommended Practices

CISA recommends users take defensive measures to minimize the risk of exploitation.

Recommended Practices

Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.

Recommended Practices

Locate control system networks and remote devices behind firewalls and isolating them from business networks.

Recommended Practices

When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs). Recognize VPNs may have vulnerabilities, should be updated to the most recent version available, and are only as secure as the 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.

Recommended Practices

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.

Recommended Practices

CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
