info:
name: Apache APISIX - Remote Code Execution
author: Mr-xn
severity: critical
description: A default configuration of Apache APISIX (with default API key) is vulnerable to remote code execution. An attacker can abuse the batch-requests plugin to send requests to bypass the IP restriction of Admin API. When the admin key was changed or the port of Admin API was changed to a port different from the data panel, the impact is lower. But there is still a risk to bypass the IP restriction of Apache APISIX's data panel. There is a check in the batch-requests plugin which overrides the client IP with its real remote IP. But due to a bug in the code, this check can be bypassed.

remediation: Upgrade to 2.10.4 or 2.12.1. Or, explicitly configure the enabled plugins in `conf/config.yaml` and ensure `batch-requests` is disabled. (Or just comment out `batch-requests` in `conf/config-default.yaml`).
