不对外网开放+改环境变量。
能够单独引入指定版本 log4j2 的项目单独引入修复的版本。 |

临时解决，设定参数：formatMsgNoLookups=true
Temporary Mitigation As per this discussion on HackerNews: The 'formatMsgNoLookups' property was added in version 2.10.0, per the JIRA Issue LOG4J2-2109 [1] that proposed it. Therefore the 'formatMsgNoLookups=true' mitigation strategy is available in version 2.10.0 and higher, but is no longer necessary with version 2.15.0, because it then becomes the default behavior [2][3]. If you are using a version older than 2.10.0 and cannot upgrade, your mitigation choices are: Modify every logging pattern layout to say %m{nolookups} instead of %m in your logging config files, see details at https://issues.apache.org/jira/browse/LOG4J2-2109 (only works on versions >= 2.7) or, Substitute a non-vulnerable or empty implementation of the class org.apache.logging.log4j.core.lookup.JndiLookup, in a way that your classloader uses your replacement instead of the vulnerable version of the class. Refer to your application's or stack's classloading documentation to understand this behavior. 参考 https://www.lunasec.io/docs/blog/log4j-zero-day/ |

补充一个
For releases from 2.0-beta9 to 2.10.0, the mitigation is to remove the JndiLookup class from the classpath: zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class. https://logging.apache.org/log4j/2.x/ |

如果业务运行在内网，需要很注意这个问题吗？我个人感觉是没必要啊，没有入口可以注入 LOG 吧？

我提供一个思路，不知道对不对，用 nginx 来拦截输入，匹配关键字
