I want to inject code into a binary, so the way that I tried is to add a section in the end of the file, and then add the whole program headers at the end of the file, then change the elf header's e_phoff, e_shnum, e_phnum, e_shoff.
Then add a str in .shstrtab section, add code in the end
this is some part of my code:
def pack(self, d):
res = ''
for field_name, field_type in d._fields_:
t = field_type
i = getattr(d, field_name)
if t == c_uint:
res += struct.pack('I', i)
elif t == c_ubyte:
res += struct.pack('B', i)
elif t == c_ulonglong:
res += struct.pack('Q', i)
elif t == c_ushort:
res += struct.pack('H', i)
else:
try:
length = field_type._length_
for item in i:
res += struct.pack('b', item)
except Exception as e:
print e
return bytearray(res)
def align(self, res):
return (len(res)+15) & ~15
def modifySectionHeader(self, s, l, sz=False):
if sz == False:
s.sh_offset += l
if s.sh_addr != 0:
s.sh_addr += l
else:
s.sh_size += l
def add(self, res, c, f, r = None):
if r == None:
l = len(c)
res[f:f+l] = c
self.modifiedPos = f+l
else:
c += r
self.add(res, c, f)
def InsertOpcode(self, opcode):
# make the length align to 0x10
code_length = self.align(opcode)
# I will add a section at the end of the file, and then add program header to the end
# and then add a LOAD segment
modifiedSize = len(self.bin) + \
(len(self.programHeaders)+1)*self.elfHeader.e_phentsize + \
code_length + self.elfHeader.e_shentsize
self.modifiedBin = ['\x00' for _ in range(modifiedSize)]
# pack function is to change ctypes struct into bytearray
if self.mode == CS_MODE_64:
tmpElfHeader = Elf64_Ehdr.from_buffer_copy(self.pack(self.elfHeader))
addedSegment = Elf64_Phdr.from_buffer_copy(self.pack(self.getLOADSegment()))
addedSection = Elf64_Shdr.from_buffer_copy(self.pack(self.findSectionByName('.text')))
elif self.mode == CS_MODE_32:
tmpElfHeader = Elf32_Ehdr.from_buffer_copy(self.pack(self.elfHeader))
addedSegment = Elf32_Phdr.from_buffer_copy(self.pack(self.getLOADSegment()))
addedSection = Elf32_Shdr.from_buffer_copy(self.pack(self.findSectionByName('.text')))
tmpElfHeader.e_phoff = len(self.bin) + self.elfHeader.e_shentsize + 8
tmpElfHeader.e_phnum += 1
tmpElfHeader.e_shnum += 1
tmpElfHeader.e_shoff += 8
# add function is to add the bytearray of string into the third arg's point
self.add(self.modifiedBin, self.pack(tmpElfHeader), 0)
elfHeaderLength = len(self.pack(tmpElfHeader))
shstrtab_idx = self.elfHeader.e_shstrndx
shstrtab = self.sectionHeaders[shstrtab_idx]
shstrtab_offset = shstrtab.sh_offset
shstrtab_size = shstrtab.sh_size
shstrtab.sh_size += 8
self.add(self.modifiedBin, self.bin[elfHeaderLength:shstrtab_offset+shstrtab_size], self.modifiedPos)
name_offset = self.modifiedPos
# this is to add the new section's name
self.add(self.modifiedBin, '.added'.ljust(8, '\x00'), self.modifiedPos)
stop_offset = self.elfHeader.e_shoff + self.elfHeader.e_shentsize*shstrtab_idx
#copy the rest of unchange bytes
self.add(self.modifiedBin, self.bin[shstrtab_offset+shstrtab_size:stop_offset], self.modifiedPos)
self.add(self.modifiedBin, self.pack(shstrtab), self.modifiedPos)
# modify remained section's offset , make them +8
for i in range(shstrtab_idx+1, len(self.sectionHeaders)):
section = self.sectionHeaders[i]
if section.sh_offset > shstrtab_offset:
self.modifySectionHeader(section, 8)
self.add(self.modifiedBin, self.pack(section), self.modifiedPos)
code_offset = self.modifiedPos + tmpElfHeader.e_shentsize + tmpElfHeader.e_phnum * tmpElfHeader.e_phentsize
addedSection.sh_offset = code_offset
addedSection.sh_size = code_length
code_address = (self.entry & ~0xfffff) + code_offset
addedSection.sh_addr = code_address
addedSection.sh_name = name_offset - shstrtab_offset
# add the added section
self.add(self.modifiedBin, self.pack(addedSection), self.modifiedPos)
# add program headers
for segment in self.programHeaders:
self.add(self.modifiedBin, self.pack(segment), self.modifiedPos)
addedSegment.p_offset = code_offset
addedSegment.p_vaddr = code_address
addedSegment.p_paddr = code_address
addedSegment.p_filesz = code_length
addedSegment.p_memsz = code_length
addedSegment.p_align = 8
# add the added segment
self.add(self.modifiedBin, self.pack(addedSegment), self.modifiedPos)
# add code
self.add(self.modifiedBin, opcode.ljust(code_length, '\x00'), self.modifiedPos)
with open('patch', 'wb') as f:
f.write(bytearray(self.modifiedBin))
and then when i use gdb to run it, I got this:
