Loading vulnerability…
A buffer overflow vulnerability exists in the /cgi-bin/wlogin.cgi component of certain DrayTek Vigor routers (such as Vigor3910 before firmware version 4.3.1.1). The vulnerability is triggered by sending an overly long username or password to the 'aa' or 'ab' fields, resulting in a buffer overflow condition.

This repository provides a proof-of-concept (PoC) exploit for CVE-2022-32548, a remote code execution vulnerability affecting multiple DrayTek router models. The exploit targets a buffer overflow in the web management interface at the /cgi-bin/wlogin.cgi endpoint, specifically via the username and password fields (base64-encoded as 'aa' and 'ab'). The main script, CVE-2022-32548-mass.py, is a Python tool designed to scan and exploit multiple IP addresses in parallel using threading, and it saves the list of vulnerable devices to a file (vulns.txt). The README.md contains detailed information about the vulnerability, affected device models and firmware versions, and usage notes. The actual exploit script is not included in the provided content, but a download link is referenced. The attack vector is network-based, requiring access to the web management interface of the target device.
