CVE-2022-23634— Puma 信息泄露漏洞

Information Exposure when using Puma with Rails

Puma is a Ruby/Rack web server built for parallelism. Prior to `puma` version `5.6.2`, `puma` may not always call `close` on the response body. Rails, prior to version `7.0.2.2`, depended on the response body being closed in order for its `CurrentAttributes` implementation to work correctly. The combination of these two behaviors (Puma not closing the body + Rails' Executor implementation) causes information leakage. This problem is fixed in Puma versions 5.6.2 and 4.3.11. This problem is fixed in Rails versions 7.02.2, 6.1.4.6, 6.0.4.6, and 5.2.6.2. Upgrading to a patched Rails _or_ Puma version fixes the vulnerability.

信息暴露

Puma 信息泄露漏洞

Puma是美国Evan Phoenix个人开发者的一款针对高并发应用的Web服务器。 Puma 存在信息泄露漏洞，该漏洞源于在puma版本5.6.2之前，puma可能并不总是在响应体上调用close，在版本7.0.2.2之前，Rails依赖于关闭响应体，以便其“CurrentAttributes”实现正确工作。这两种行为(Puma不关闭主体+ Rails的Executor实现)的结合会导致信息泄漏。
