WWW2Exec - GOT/PLT
In heap exploitation, a common technique is to overwrite the free
GOT address to point to system
. This way, when the free
function is called on a chunk containing the string "/bin/sh"
, a shell will be executed. This technique is often used in CTFs.
Strlen2system
Another common technique is to overwrite the strlen
GOT address to point to system
. This way, if the strlen
function is called with user input, it's possible to pass the string "/bin/sh"
and get a shell. This technique can also be used with the puts
function, which will call strlen
with the user input.
These techniques are often used in heap exploitation CTFs to gain code execution. For more information, you can check out the Heap Exploitation guide.
Heap Exploitation
Heap exploitation is a set of techniques that can be used to exploit memory management vulnerabilities in C programs. These vulnerabilities can be used to corrupt data, the control flow of a program, or to leak information. Heap exploitation is a common technique used in CTFs to exploit memory corruption vulnerabilities in binary programs.
There are several techniques that can be used to exploit the heap, including:
Fastbin Duplication
House of Force
House of Spirit
House of Lore
House of Orange
Tcache Poisoning
These techniques can be used to exploit memory corruption vulnerabilities in the heap in order to gain control over program execution. For more information, you can check out the Heap Exploitation guide.
Note: The above information is based on the assumption that you are familiar with the basics of heap memory management in C. If you are not familiar with this topic, I would recommend reading up on it before attempting to understand heap exploitation.
Heap exploitation is a technique used to exploit memory management vulnerabilities in C programs. These vulnerabilities can be used to corrupt data, control the flow of a program, or even execute arbitrary code. Heap exploitation is a common technique used in CTFs and can be used to exploit a wide range of vulnerabilities.
There are several techniques that can be used to exploit heap memory vulnerabilities, including:
