SecureApp PWN
The developers of SecureApp aren’t too secure with their C programs. I was able to cause a segmentation fault error somehow and analysing the functions shows there is a very interesting one called exploitme.
Can you exploit the buffer overflow vulnerability and execute the exploitme function?
If you are stuck doing this challenge, follow the buffer overflow demo that is provided. Once you have a working exploit you can use the Python telnetlib module to send your payloads to the server. Alternatively you can install pwnlib, which is an exploitation development framework.
