CVE-2020-13945 - Apache APISIX Remote Code Execution (RCE)

This repository contains a proof-of-concept (PoC) exploit for a vulnerability in Apache APISIX. The vulnerability arises when the Admin API is enabled and the access IP restriction rules are deleted, allowing the default token to access APISIX management data. This affects versions 1.2, 1.3, 1.4, and 1.5.

Overview

Apache APISIX is a dynamic, real-time, high-performance API gateway. A critical security vulnerability exists in versions 1.2 to 1.5, where enabling the Admin API and deleting the Admin API access IP restriction rules permits unauthorized access using the default token.

Affected Versions

• Apache APISIX 1.2
• Apache APISIX 1.3
• Apache APISIX 1.4
• Apache APISIX 1.5

Setup

1. Clone the repository:

   git https://github.com/K3ysTr0K3R/CVE-2020-13945-EXPLOIT.git
   cd CVE-2020-13945

2. Install dependencies:

   pip install -r requirements.txt

Usage

1. Ensure Apache APISIX is running and the Admin API is enabled.
2. Run the exploit script:

   python CVE-2020-13945.py -u <target>
   python CVE-2020-13945.py -f <target_file> -t 77

   Replace <target(s)> with the url of the target APISIX instance to exploit.

Mitigation

To mitigate this vulnerability:

1. Do not delete the Admin API access IP restriction rules. Ensure they are configured correctly to restrict access to trusted IPs only.
2. Change the default token. Use a strong, unique token for accessing the Admin API.

For detailed information on configuring security settings, refer to the Apache APISIX documentation.
