# CVE-2025-60751
PoC for CVE-2025-60751

Affected product: [Geographiclib](https://github.com/geographiclib/geographiclib) <= v2.5.1

The full writeup article is available at [https://zer0matt.github.io/CVE-2025-60751/](https://zer0matt.github.io/CVE-2025-60751/)

### Description
A stack buffer overflow occurs when GeoConvert receives a crafted input.
The overflow occurs because the program does not properly validate an internal index, allowing an out-of-bounds write on the stack.

An attacker can exploit this vulnerability to hijack the program's control flow by overwriting a return address to point to a libc function (ret2libc) and execute arbitrary code using a ROP chain.

### Usage
```
[~] python3 CVE-2025-60751.py

```
### Notes
Remember to fix the addresses accordingly in order to build your own ROP Chain, addresses can vary due to memory defenses techniques such as ASLR.
