Two of these are rated critical in severity.\n\nTreck's embedded TCP/IP stack is deployed worldwide in manufacturing, information technology, healthcare, and transportation systems.\n\nThe most severe of them is a heap-based buffer overflow vulnerability (**CVE-2020-25066**) in the Treck HTTP Server component that could permit an adversary to crash or reset the target device and even execute remote code. It has a CVSS score of 9.8 out of a maximum of 10.\n\nThe second flaw is an out-of-bounds write in the IPv6 component (**CVE-2020-27337**, CVSS score 9.1) that could be exploited by an unauthenticated user to cause a DoS condition via network access.\n\nTwo other vulnerabilities concern an out-of-bounds read in the IPv6 component (**CVE-2020-27338**, CVSS score 5.9) that could be leveraged by an unauthenticated attacker to cause DoS and an improper input validation in the same module (**CVE-2020-27336**, CVSS score 3.7) that could result in an out-of-bounds read of up to three bytes via network access.\n\nTreck [recommends](<https://treck.com/vulnerability-response-information/>) users to update the stack to version 6.0.1.68 to address the flaws. In cases where the latest patches cannot be applied, it's advised that firewall rules are implemented to filter out packets that contain a negative content-length in the HTTP header.\n\nThe disclosure of new flaws in Treck TCP/IP stack comes six months after Israeli cybersecurity company JSOF uncovered 19 vulnerabilities in the software library \u2014 dubbed [Ripple20](<https://thehackernews.com/2020/06/new-critical-flaws-put-billions-of.html>) \u2014 that could make it possible for attackers to gain complete control over targeted IoT devices without requiring any user interaction.\n\nWhat's more, earlier this month, Forescout researchers revealed 33 vulnerabilities \u2014 collectively called [AMNESIA:33](<https://thehackernews.com/2020/12/amnesia33-critical-tcpip-flaws-affect.html>) \u2014 impacting open-source TCP/IP protocol stacks that could be abused by a bad actor to take over a vulnerable system.\n\nGiven the complex IoT supply chain involved, the company has released a new detection tool called \"project-memoria-detector\" to identify whether a target network device runs a vulnerable TCP/IP stack in a lab setting.\n\nYou can access the tool via GitHub [here](<https://github.com/Forescout/project-memoria-detector>).\n\n \n\n\nFound this article interesting?

MITIGATIONS\n\nTreck recommends users apply the latest version of the affected products (Treck TCP/IP 6.0.1.68 or later versions). To obtain patches, email [security@treck.com](<mailto:security@treck.com>)\n\nTreck recommends users who cannot apply the latest patches to implement firewall rules to filter out packets that contain a negative content length in the HTTP header.\n\nFor more detailed information on the vulnerabilities and the mitigating controls, please see the [Treck advisory](<https://treck.com/vulnerability-response-information/>). \n\nCISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:\n\n * Minimize network exposure for all control system devices and/or systems, and ensure that they are [not accessible from the Internet](<https://us-cert.cisa.gov/ics/alerts/ICS-ALERT-10-301-01>).\n * Locate control system networks and remote devices behind firewalls, and isolate them from the business network.\n * When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.\n\nCISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. \n \nCISA also provides a section for [control systems security recommended practices](<https://us-cert.cisa.gov/ics/recommended-practices>) on the ICS webpage on [us-cert.cisa.gov](<https://us-cert.cisa.gov/ics>). Several recommended practices are available for reading and download, including [Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies](<https://us-cert.cisa.gov/sites/default/files/recommended_practices/NCCIC_ICS-CERT_Defense_in_Depth_2016_S508C.pdf>).\n\nAdditional mitigation guidance and recommended practices are publicly available on the [ICS webpage on us-cert.cisa.gov](<https://us-cert.cisa.gov/ics>) in the Technical Information Paper, [ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies](<https://us-cert.cisa.gov/ics/tips/ICS-TIP-12-146-01B>). \n \nOrganizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.\n\nHigh skill level is needed to exploit. No known public exploits specifically target these vulnerabilities.\n\n## \nContact Information\n\nFor any questions related to this report, please contact the CISA at: \n \nEmail: [CISAservicedesk@cisa.dhs.gov](<mailto:cisaservicedesk@cisa.dhs.gov>) \nToll Free: 1-888-282-0870\n\nFor industrial control systems cybersecurity information: https://us-cert.cisa.gov/ics \nor incident reporting: https://us-cert.cisa.gov/report\n\nCISA continuously strives to improve its products and services.
