Description
This module exploits combined heap and stack buffer overflows for QNAP NAS and NVR devices to dump the admin (root) shadow hash from memory via an overwrite of __libc_argv[0] in the HTTP-header-bound glibc backtrace.
A binary search is performed to find the correct offset for the BOFs. Since the server forks, blind remote exploitation is possible, provided the heap does not have ASLR.
