VAR-202111-1282

Vulnerability from variot - Updated: 2023-12-18 13:12

The uri-block plugin in Apache APISIX before 2.10.2 uses $request_uri without verification. The $request_uri is the full original request URI without normalization. This makes it possible to construct a URI to bypass the block list on some occasions. For instance, when the block list contains "^/internal/", a URI like //internal/ can be used to bypass it. Some other plugins also have the same issue. And it may affect the developer's custom plugin. Apache APISIX Contains a command injection vulnerability.Information may be obtained. Apache Apisix is a cloud-native microservice API gateway service of the Apache Foundation in the United States. The software is implemented based on OpenResty and etcd, with dynamic routing and plug-in hot loading, suitable for API management under the microservice system.

Apache APISIX has a security vulnerability, which stems from improper design or implementation issues in the code development process of network systems or products. No detailed vulnerability details are currently provided
