Apache APISIX Remote Code Execution (CVE-2022-24112) Exploit
Summary
An attacker can abuse the batch-requests plugin to send requests to
bypass the IP restriction of Admin API.
A default configuration of Apache APISIX (with default API key) is
vulnerable to remote code execution.
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.
