EIP tracks 1 public exploit for CVE-2018-25220. PoCs published by Juan Sacco.
AI-analyzed exploit summary This exploit demonstrates a buffer overflow vulnerability in Bochs 2.6-5, leveraging a ROP chain to execute arbitrary code (specifically, spawning a shell). The PoC constructs a payload with padding and ROP gadgets to bypass memory protections and achieve code execution.
Description
Bochs 2.6-5 contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by supplying an oversized input string to the application. Attackers can craft a malicious payload with 1200 bytes of padding followed by a return-oriented programming chain to overwrite the instruction pointer and execute shell commands with application privileges.
