Rockwell Automation encourages users to apply the latest firmware versions that address the identified vulnerabilities.\n\nRockwell Automation\u2019s new firmware version for the Allen-Bradley MicroLogix 1400 Series B controllers, FRN 21.00, is available at the following location:\n\n[http://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?Keyword=1766-Lxx&amp;crumb=112](<http://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?Keyword=1766-Lxx&crumb=112>)\n\nThere are no firmware versions to address these vulnerabilities in the Allen-Bradley MicroLogix 1100 or MicroLogix 1400 Series A controllers, but Rockwell Automation has offered some compensating controls. Rockwell Automation reports that users can disable the web server on the Allen-Bradley MicroLogix 1100 and 1400 Series A controllers to protect against the exploitation of the improper restriction of excessive authentication attempts and weak password requirements vulnerabilities.\n\nRockwell Automation recommends that if it is not needed, users should consider disabling the web server to further mitigate these threats.\n\n * Disable the web server on the MicroLogix 1100 and 1400 controllers, if not needed, as it is enabled by default. See Knowledge Base article: 732398 for detailed instructions on disabling the web server. The Web Server Tech Note, KB: 732398 \u2013 How to Disable the Web Server in MicroLogix 1100 and 1400 is available at the following URL with a valid account:\n\n<https://rockwellautomation.custhelp.com/app/answers/detail/a_id/732398>\n\n * Set the mode to RUN via LCD soft keyswitch to prohibit any re-enabling of the web server while the keyswitch is in this mode.\n\nNCCIC/ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. 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.\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\nICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.\n\nICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.\n\nAdditional mitigation guidance and recommended practices are publicly available in the ICS\u2011CERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site.\n\nOrganizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.\n\nIn addition, ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:\n\n 1. Do not click web links or open unsolicited attachments in email messages.\n 2. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.\n 3. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.\n\nNo known public exploits specifically target these vulnerabilities.\n\n## VULNERABILITY OVERVIEW\n\n## [PREDICTABLE VALUE RANGE FROM PREVIOUS VALUES CWE-343](<https://cwe.mitre.org/data/definitions/343.html>)\n\nInsufficiently random TCP initial sequence numbers are generated, which may allow an attacker to predict the numbers from previous values. This may allow an attacker to spoof or disrupt TCP connections, resulting in a denial of service for the target device.\n\n[CVE-2017-7901](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-7901>) has been assigned to this vulnerability.
