漏洞描述Apache Log4j2 是一个基于 Java 的日志记录工具。该工具重写了 Log4j 框架，并且引入了大量丰富的特性。该日志框架被大量用于业务系统开发，用来记录日志信息。 在大多数情况下，开发者可能会将用户输入导致的错误信息写入日志中。攻击者利用此特性可通过该漏洞构造特殊的数据请求包，最终触发远程代码执行。由于该漏洞影响范围极广，建议广大用户及时排查相关漏洞，经过白帽汇安全研究院分析确认，目前市面有多款流行的系统都受影响。 该漏洞危害等级：严重 影响范围Apache Log4j 2.x < 2.15.0-rc2 已知影响组件- Apache Struts2

Linux： sudo find / -name "*log4j-*.jar"![]()
Windows： *log4j*.jar![]()
攻击排查日志排查： 攻击者在利用前通常采用dnslog方式进行扫描、探测，对于常见利用方式可通过应用系统报错日志中的 "javax.naming.CommunicationException" "javax.naming.NamingException: problem generating object using object factory" "Error looking up JNDI resource"关键字进行排查。 流量排查： 攻击者的数据包中可能存在：“${jndi:rmi”、“${jndi:ldap”字样，可根据此类关键字进行排查。 漏洞复现![]()
Vulfocus 靶场环境目前 Vulfocus 已经集成 Log4j2 环境，可通过以下链接启动环境测试： http://vulfocus.fofa.so/#/dashboard?image_id=3b8f15eb-7bd9-49b2-a69e-541f89c4216c 也可通过 docker pull vulfocus/log4j2-rce-2021-12-09:latest 拉取本地环境运行，本地启动命令：docker run -d -P vulfocus/log4j2-rce-2021-12-09:latest ![]()
修复建议1、禁止使用 log4j 服务器外连，升级 idk 11.0.1 8u191 7u201 6u211 或更高版本。 2、升级至 log4j-2.15.0-rc2： 下载地址：https://github.com/apache/logging-log4j2/releases/tag/log4j-2.15.0-rc2 3、紧急缓解措施： （1） 修改 jvm 参数 -Dlog4j2.formatMsgNoLookups=true （2） 修改配置 log4j2.formatMsgNoLookups=True （3） 将系统环境变量 FORMAT_MESSAGES_PATTERN_DISABLE_LOOKUPS 设置 为 true 参考[1] https://github.com/apache/logging-log4j2/releases/tag/log4j-2.15.0-rc1 [2] [LOG4J2-3201] Limit the protocols jNDI can use and restrict LDAP. - ASF JIRA (apache.org) [3] ASF Git Repos - logging-log4j2.git/blob - log4j-core/src/test/java/org/apache/logging/log4j/core/lookup/JndiRestrictedLookupTest.java [4] https://mp.weixin.qq.com/s/wC7mrK1Y4DYz9_yW4fLzbw [5] https://help.aliyun.com/noticelist/articleid/1060971232.html [6] https://mp.weixin.qq.com/s/C4zeXHKHDqPeRuLytO7Fzw
