Python Exploit Development Assistance: PEDAL

PEDAL – Python Exploit Development Assistance for GDB Lite

---

This version has been extended to add some features and give dual-compatibility with Python2 and Python3.

• Python2 and Python3 compatibility
• Line width wrapping on banners
• Colorize stack and heap differently than regular data
• Show registers alongside stack output (and ‘telescope’ command)
• Basic support for ARM and PPC registers
• Support for passing GDB variables to PEDA routines (e.g. hexdump $pc)

PEDAL Features:

These are the standard features of PEDA:

• Enhance the display of gdb: colorize and display disassembly codes, registers, memory information during debugging.
• Add commands to support debugging and exploit development (for a full list of commands usepeda help):
  • aslr — Show/set ASLR setting of GDB
  • checksec — Check for various security options of binary
  • dumpargs — Display arguments passed to a function when stopped at a call instruction
  • dumprop — Dump all ROP gadgets in specific memory range
  • elfheader — Get headers information from debugged ELF file
  • elfsymbol — Get non-debugging symbol information from an ELF file
  • lookup — Search for all addresses/references to addresses which belong to a memory range
  • patch — Patch memory start at an address with string/hexstring/int
  • pattern — Generate, search, or write a cyclic pattern to memory
  • procinfo — Display various info from /proc/pid/
  • pshow — Show various PEDA options and other settings
  • pset — Set various PEDA options and other settings
  • readelf — Get headers information from an ELF file
  • ropgadget — Get common ROP gadgets of binary or library
  • ropsearch — Search for ROP gadgets in memory
  • searchmem|find — Search for a pattern in memory; support regex search
  • vmmap — Get virtual mapping address ranges of section(s) in debugged process
  • xormem — XOR a memory region with a key
