![]() ![]() Federal agencies are required to comply with these directives. Section 2205(3) of the Homeland Security Act of 2002, as amended, delegates this authority to the Director of the Cybersecurity and Infrastructure Security Agency. Code, authorizes the Secretary of Homeland Security, in response to a known or reasonably suspected information security threat, vulnerability, or incident that represents a substantial threat to the information security of an agency, to “issue an emergency directive to the head of an agency to take any lawful action with respect to the operation of the information system, including such systems used or operated by another entity on behalf of an agency, that collects, processes, stores, transmits, disseminates, or otherwise maintains agency information, for the purpose of protecting the information system from, or mitigating, an information security threat.” 44 U.S.C. This page contains a web-friendly version of the Cybersecurity and Infrastructure Security Agency’s Emergency Directive 22-02, “Mitigate Apache Log4j Vulnerability ”. Agencies should leverage the updated guidance to tailor their internal temporary mitigation efforts going forward. BOD 22-01 still requires agencies to fully remediate the Log4j vulnerabilities wherever updates are available across all impacted software. Please refer to updated guidance on the Apache Log4j Vulnerability Guidance page. Patch and Mitigation, or the first link above.CISA has closed ED 22-02 and transitioned required actions for Log4J vulnerability to CISA’s BOD 22-01 Reducing the Significant Risk or Known Exploited Vulnerabilities. If you must keep the log4j.jar file because your software depends on it then it is recommended you switch to log4j version 2 and follow the suggestions as described for example at: We recommend that you review this release from The Mathworks on this issue and contact them with any additional queries.įinally, note that Log4j version 1 is old and has other vulnerabilities so we recommend that you remove the Matlab-related log4j.jar file. The default Windows location for compiled products (Solo, Solo+MIA, or Solo_Predictor) is, for example Solo_Predictor:Ĭ:\Program Files\EVRI\Solo_Predictor\application\java\jarext\log4j.jarĬ:\Program Files\MATLAB\MATLAB Runtime\v99\java\jarext\log4j.jar The file should be listed by the appropriate search tool and our limited testing thus far indicates no issues with Solo or Solo_Predictor. Note that under macOS and Linux, you will have to navigate inside of the application bundle for MATLAB under those platforms.įor our compiled products Solo (and variants) and Solo_Predictor, this log4j.jar file will found under the folder structure for the MATLAB Runtime engine, the location of which is operating system dependent. If you have installed the Matlab Runtime separately then it will be installed there, for example at:Ĭ:\Program Files\MATLAB\MATLAB Runtime\v99\java\jarext If you are a PLS_Toolbox user, you will find this file starting from the top level MATLAB folder under topLevelMATLABfolder/java/jarext, for example if you are using Matlab R2020b:Ĭ:\Program Files\MATLAB\R2020b\java\jarext PLS_Toolbox or compiled products (Solo, Solo+MIA, Solo_Predictor.) should work normally as they do not depend on log4j. Our testing thus far indicates that removal of the Matab log4j.jar file will not affect EVRI software other than causing some error messages to appear upon the startup of MATLAB. We do not use log4j in Eigenvector software. It is only when log4j is used on an exposed server that the vulnerability can be a problem. The presence of a log4j jar file on a computer does not imply a vulnerability. ![]() Apache Log4j Security Vulnerabilities states "Log4j 1.x is not impacted by this vulnerability.". ![]() This instance of log4j is the older version 1, which does not have the Log4Shell vulnerability. See Wikipedia: Log4Shell Possible Solutions:Īll of our products are based upon the MATLAB platform, and each installation of MATLAB includes a copy of the log4j.jar file. What should I do about the log4j.jar security issue "Log4Shell" discovered in December 2021? ![]()
