EXECUTIVE SUMMARY * **CVSS v3 7.5** * **ATTENTION:** Exploitable remotely/low skill level to exploit * **Vendor:** Inductive Automation * **Equipment:** Ignition 8 * **Vulnerability:** Missing Authorization ## 2\. RISK EVALUATION Successful exploitation of this vulnerability could allow an attacker to gain access to sensitive information. ## 3\. TECHNICAL DETAILS ### 3.1 AFFECTED PRODUCTS The following versions of Inductive Automation Ignition are affected: * Inductive Automation Ignition 8: All versions prior to 8.0.13 ### 3.2 VULNERABILITY OVERVIEW #### 3.2.1 [MISSING AUTHORIZATION CWE-862](https://cwe.mitre.org/data/definitions/862.html) The affected product is vulnerable to an information leak, which may allow an attacker to obtain sensitive information. An HTTP request to the unprotected API could be used to determine whether an arbitrary file path exists on the filesystem. No authentication is required to perform this exploit. [CVE-2020-14520](http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-14520) has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is ([AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)). ### 3.3 BACKGROUND * **CRITICAL INFRASTRUCTURE SECTORS:** Critical Manufacturing, Energy, Information Technology * **COUNTRIES/AREAS DEPLOYED:** United States * **COMPANY HEADQUARTERS LOCATION:** United States ### 3.4 RESEARCHER Mashav Sapir of Claroty reported this vulnerability to CISA. ## 4\. MITIGATIONS Inductive Automation recommends users upgrade the Ignition software to [v8.0.13](https://inductiveautomation.com/downloads/releasenotes/8.0.13) CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should: * Minimize network exposure for all control system devices and/or systems, and ensure that they are [not accessible from the Internet](https://www.us-cert.gov/ics/alerts/ICS-ALERT-10-301-01). * Locate control system networks and remote devices behind firewalls, and isolate them from the business network. * 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. 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](https://www.us-cert.gov/ics/recommended-practices) on the ICS webpage on [us-cert.gov](https://www.us-cert.gov/ics). Several recommended practices are available for reading and download, including [Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies](https://www.us- cert.gov/sites/default/files/recommended_practices/NCCIC_ICS- CERT_Defense_in_Depth_2016_S508C.pdf). Additional mitigation guidance and recommended practices are publicly available on the [ICS webpage on us-cert.gov](https://www.us-cert.gov/ics) in the Technical Information Paper, [ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies](https://www.us-cert.gov/ics/tips/ICS- TIP-12-146-01B). Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents. No known public exploits specifically target this vulnerability.
