Loading vulnerability…
CVE-2022-39066 is a SQL injection vulnerability in ZTE MF286R devices, specifically in the phonebook interface. The vulnerability arises from insufficient validation of input parameters, allowing an authenticated attacker to inject and execute arbitrary SQL commands on the underlying database. This affects versions prior to MF286R_B07.

This repository contains a proof-of-concept exploit for CVE-2022-39066, targeting ZTE router firmware running the goahead webserver. The exploit leverages a SQL injection vulnerability in the PHONE_BLOCK_ADD handler to write arbitrary files to the device's filesystem. The main exploit script (exploit.py) performs the following steps: authenticates to the web interface using a base64-encoded admin password, crafts a malicious SQL payload to create and write to a file (e.g., /var/log/webshow_messages), and then retrieves the contents of the written file via the ExportSyslog.sh endpoint. The exploit demonstrates the ability to manipulate the device's database and filesystem, which could be leveraged for further attacks. The repository consists of a README.md with usage instructions and technical details, and a single Python exploit script. The attack vector is network-based, requiring access to the device's web interface and valid admin credentials.
