Matlab log4j11/18/2023 ![]() ![]() "An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled," the Apache Foundation said in an advisory. The bug has scored a perfect 10 on 10 in the CVSS rating system, indicative of the severity of the issue. Tracked as CVE-2021-44228 and by the monikers Log4Shell or LogJam, the issue concerns a case of unauthenticated, remote code execution (RCE) on any application that uses the open-source utility and affects versions Log4j 2.0-beta9 up to 2.14.1. Does your ImageJ installation have jars/logback-classic-1.1.1.The Apache Software Foundation has released fixes to contain an actively exploited zero-day vulnerability affecting the widely-used Apache Log4j Java-based logging library that could be weaponized to execute malicious code and allow a complete takeover of vulnerable systems. ![]() ![]() This is fine as long as you do not need to run JavaScript scripts.Īs for the first two lines about log4j, those are actually a separate error from the big stack trace about JavaScript. I guess in the case of MATLAB, it is the latter, since MATLAB interfaces with Java in its own special way.įor now, one way to work around the problem is to delete the jars/scripting-javascript-x.y.z.jar file from your ImageJ installation. But for now, we have this annoying error in cases where the JavaScript extension in jre/lib/ext is either not present, or not available to the JVM for some reason. I heard they are going to change this in Java 9, fortunately. Very sorry for the delay in reply, assume you switched your MATLAB over to Java 8 as instructed?Įven if so, JavaScript in Java 8 is a funny beast because the JavaScript library is on the Java extensions path. : No such script engine: javascriptĪt .findFactory(AdaptedScriptLanguage.java:151)Īt .(AdaptedScriptLanguage.java:73)Īt .javascript.JavaScriptScriptLanguage.(JavaScriptScriptLanguage.java:59)Īt 0(Native Method)Īt (NativeConstructorAccessorImpl.java:62)Īt (DelegatingConstructorAccessorImpl.java:45)Īt .newInstance(Constructor.java:423)Īt (Class.java:442)Īt .createInstance(PluginInfo.java:304)Īt .createInstance(DefaultPluginService.java:236)Īt .createInstances(DefaultPluginService.java:225)Īt .createInstancesOfType(DefaultPluginService.java:216)Īt .initInstances(AbstractSingletonService.java:125)Īt .getInstances(AbstractSingletonService.java:72)Īt .initScriptLanguageIndex(DefaultScriptService.java:347)Īt .scriptLanguageIndex(DefaultScriptService.java:312)Īt .getIndex(DefaultScriptService.java:119)Īt .canHandleFile(DefaultScriptService.java:235)Īt .discoverScripts(ScriptFinder.java:131)Īt .discoverScripts(ScriptFinder.java:125)Īt .findScripts(ScriptFinder.java:94)Īt .initScripts(DefaultScriptService.java:388)Īt .scripts(DefaultScriptService.java:330)Īt .getScripts(DefaultScriptService.java:169)Īt .getScriptsAndNonLegac圜ommands(LegacyService.java:609)Īt 1Helper.addMenuItems(IJ1Helper.java:676)Īt .initialize(LegacyService.java:472)Īt .createServiceRecursively(ServiceHelper.java:353)Īt .createExactService(ServiceHelper.java:269)Īt .loadService(ServiceHelper.java:231)Īt .createServiceRecursively(ServiceHelper.java:340)Īt .loadService(ServiceHelper.java:194)Īt .loadServices(ServiceHelper.java:166)Īt .(Context.java:278)Īt .(Context.java:234)Īt .(Context.java:174)Īt .(Context.java:160)Īt .launch(ImageJMATLAB.java:151)Īt .start(ImageJMATLAB.java:105)Īt .start(ImageJMATLAB.java:92)Īt .start(ImageJMATLAB.java:81) Cannot create plugin: class='.javascript.JavaScriptScriptLanguage', name='JavaScript', priority=0.0, enabled=true, pluginType=ScriptLanguage Log4j:WARN Please initialize the log4j system properly.
