CVE-2022-24112
Apache APISIX Authentication Bypass Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 15 September 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
Description
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.
