// You can put in any shellcode you want. Just make sure that the

|
|
|
// The basic idea of this exploit is:
|
|
// 1) Create a string that has the same size as a Hashtable
|
|
// 2) Create 65536 references to it to overflow the refcount
|
|
// 3) Free one of these references
|
|
// => Refcount drops down to 0
|
|
// => String gets freed
|
|
// 4) Free some more zvals
|
|
// 5) Create a new array with one element
|
|
// => Put shellcode in the key
|
|
// => Hashtable struct will be in the same place as the string
|
|
// 6) Use string to directly access the content of the Hashtable
|
|
// => Read pointer to first bucket
|
|
// => Add 32 bytes, offset to array key
|
|
// => Write pointer to the destructor field
|
|
// 7) Unset array => Executes code in $shellcode
