Vulnerability from cnvd

Title: Puma信息泄露漏洞

Description:

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。目前没有详细的漏洞细节提供。

Severity: 高

Severity ?

8.0 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:N

CWE

CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor

Summary

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.

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\u0027 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."
