arbitrary-write-to-rce

To convert an arbitrary write into code execution, you can overwrite critical targets like GOT entries, libc hooks, or _IO_FILE vtables to hijack control flow and execute arbitrary code.

Best arbitrary write targets vary by glibc version but include GOT, hooks, _IO_FILE vtable, __exit_funcs, TLS_dtor_list, and _dl_fini, ensuring compatibility across multiple glibc releases.

Overwriting TLS_dtor_list or _IO_FILE vtable achieves code execution by manipulating internal glibc structures called during program exit or stream operations, redirecting execution to attacker-controlled functions.

Yes, leveraging arbitrary write to RCE requires in-depth knowledge of libc, specific glibc versions, and heap/stack structures to successfully target and bypass binary protections.

Yes, arbitrary write techniques can bypass binary protections during heap exploitation, stack overflow, and format string attacks by targeting structures like modprobe_path or .fini_array.

Overwrite GOT entries for standard C binaries to redirect function calls, while C++ vtables are targeted to hijack virtual method dispatch in object-oriented programs for code execution.
