Unfortunately, adds a dep on bionic for runtime compilation.
Gets ring0, sets the (res)uid to 0 and jumps to the payload. Still some
payload issues because linux stagers don't mprotect(2) the buffer they
read(2) into. Single payloads work fine, though.
Also cleans up and improves local exploits' ability to compile C.
[SEERM #3038]
When using the reload_all command, the framework will trigger an
'undefined method module_history' error, because we're missing
an accessor.
Also, even though reload_modules returns "counts". That actually
returns a hash instead of a real count of modules... the return
value is also never actually used anywhere. But to make this
part not broken, we return the actual count.
This is a fix for issues related to:
'undefined method `[]' for nil:NilClass'
It is possible that a PDF may not have the 'Size' xref, and people
are running into the 'undefined method'[]' for NilClass' exception.
Because the pdf parser always assumes there is a Size field,
so it uses a match() function to find the value for Size, which
can be nil.
See the following bug report for example:
https://dev.metasploit.com/redmine/issues/7014
Something is still broken, my socket() is returning EAFNOSUPPORT whereas
what looks like the same syscall in wunderbar_emporium's exploit.c is
returning a socket. Similarly, my __mmap2() is returning EFAULT when
trying to map anything, not just NULL.
This can currently build an executable that creates a socket, opens a
temporary file, truncates that file with ftruncate(2) and calls
sendfile. Still needs to mmap NULL and figure out ring0 shellcode.
Baby steps.
