pwnlib.shellcraft.arm
— Shellcode for ARM¶
pwnlib.shellcraft.arm
¶
Shellcraft module containing generic ARM little endian shellcodes.
-
pwnlib.shellcraft.arm.
crash
()[source]¶ Crash.
Example
>>> run_assembly(shellcraft.crash()).poll(True) -11
-
pwnlib.shellcraft.arm.
itoa
(v, buffer='sp', allocate_stack=True)[source]¶ Converts an integer into its string representation, and pushes it onto the stack. Uses registers r0-r5.
Parameters: Example
>>> sc = shellcraft.arm.mov('r0', 0xdeadbeef) >>> sc += shellcraft.arm.itoa('r0') >>> sc += shellcraft.arm.linux.write(1, 'sp', 32) >>> run_assembly(sc).recvuntil(b'\x00') b'3735928559\x00'
-
pwnlib.shellcraft.arm.
memcpy
(dest, src, n)[source]¶ Copies memory.
Parameters: - dest – Destination address
- src – Source address
- n – Number of bytes
-
pwnlib.shellcraft.arm.
mov
(dst, src)[source]¶ Move src into dest.
Support for automatically avoiding newline and null bytes has to be done.
If src is a string that is not a register, then it will locally set context.arch to ‘arm’ and use
pwnlib.constants.eval()
to evaluate the string. Note that this means that this shellcode can change behavior depending on the value of context.os.Examples
>>> print(shellcraft.arm.mov('r0','r1').rstrip()) mov r0, r1 >>> print(shellcraft.arm.mov('r0', 5).rstrip()) mov r0, #5 >>> print(shellcraft.arm.mov('r0', 0x34532).rstrip()) movw r0, #0x34532 & 0xffff movt r0, #0x34532 >> 16 >>> print(shellcraft.arm.mov('r0', 0x101).rstrip()) movw r0, #0x101 >>> print(shellcraft.arm.mov('r0', 0xff << 14).rstrip()) mov r0, #0x3fc000 >>> print(shellcraft.arm.mov('r0', 0xff << 15).rstrip()) movw r0, #0x7f8000 & 0xffff movt r0, #0x7f8000 >> 16 >>> print(shellcraft.arm.mov('r0', 0xf00d0000).rstrip()) eor r0, r0 movt r0, #0xf00d0000 >> 16 >>> print(shellcraft.arm.mov('r0', 0xffff00ff).rstrip()) mvn r0, #(0xffff00ff ^ (-1)) >>> print(shellcraft.arm.mov('r0', 0x1fffffff).rstrip()) mvn r0, #(0x1fffffff ^ (-1))
Parameters:
-
pwnlib.shellcraft.arm.
push
(word, register='r12')[source]¶ Pushes a 32-bit integer onto the stack. Uses r12 as a temporary register.
r12 is defined as the inter-procedural scartch register ($ip), so this should not interfere with most usage.
Parameters:
-
pwnlib.shellcraft.arm.
pushstr
(string, append_null=True, register='r7')[source]¶ Pushes a string onto the stack.
Parameters: Examples
>>> print(shellcraft.arm.pushstr("Hello!").rstrip()) /* push b'Hello!\x00A' */ movw r7, #0x4100216f & 0xffff movt r7, #0x4100216f >> 16 push {r7} movw r7, #0x6c6c6548 & 0xffff movt r7, #0x6c6c6548 >> 16 push {r7}
-
pwnlib.shellcraft.arm.

-
pwnlib.shellcraft.arm.
setregs
(reg_context, stack_allowed=True)[source]¶ Sets multiple registers, taking any register dependencies into account (i.e., given eax=1,ebx=eax, set ebx first).
Parameters: Example
>>> print(shellcraft.setregs({'r0': 1, 'r2': 'r3'}).rstrip()) mov r0, #1 mov r2, r3 >>> print(shellcraft.setregs({'r0': 'r1', 'r1': 'r0', 'r2': 'r3'}).rstrip()) mov r2, r3 eor r0, r0, r1 /* xchg r0, r1 */ eor r1, r0, r1 eor r0, r0, r1
-
pwnlib.shellcraft.arm.

¶

-
pwnlib.shellcraft.arm.linux.
access
(name, type)[source]¶ Invokes the syscall access. See ‘man 2 access’ for more information.

cacheflush
()[source]¶ Invokes the cache-flush operation, without using any NULL or newline bytes.
Effectively is just:
mov r0, #0 mov r1, #-1 mov r2, #0 swi 0x9F0002How this works:
... However, SWI generates a software interrupt and to the interrupt handler, 0x9F0002 is actually data and as a result will not be read via the instruction cache, so if we modify the argument to SWI in our self-modifyign code, the argument will be read correctly.
