TiEmu Stack-Based Buffer Overflow Vulnerability Allowing Arbitrary Code Execution

A stack-based buffer overflow vulnerability has been identified in TiEmu versions through 2.08. This vulnerability arises from insufficient boundary checks on user-supplied input, allowing attackers to execute arbitrary code. The overflow can be triggered by command-line arguments passed to the application. Exploitation involves using Return-Oriented Programming (ROP) gadgets to bypass security protections and execute shellcode within the application's context.

Impact

Exploitation of this vulnerability leads to arbitrary code execution in the application's context. However, failed attempts to exploit the vulnerability cause a denial-of-service condition.

Reproduction

The vulnerability can be reproduced by creating a buffer overflow payload that includes a crafted Return-Oriented Programming (ROP) chain. This payload must be passed as a command-line argument to the TiEmu application. The ROP chain should be designed to exploit the buffer overflow by manipulating the application's control flow, ultimately leading to the execution of arbitrary code.
