Bug 829219 – <dev-ruby/actionpack-{6.0.4.3,6.1.4.3}: open redirect vulnerability

• Status: IN_PROGRESS
• Product: Gentoo Security

[Description John Helmert III 2021-12-15 00:30:13 UTC]

From URL:

"Impact
------
Specially crafted "X-Forwarded-Host" headers in combination with certain
"allowed host" formats can cause the Host Authorization middleware in Action
Pack to redirect users to a malicious website.

Impacted applications will have allowed hosts with a leading dot. For
example,
configuration files that look like this:

```
config.hosts <<  '.EXAMPLE.com'
```

When an allowed host contains a leading dot, a specially crafted Host header
can be used to redirect to a malicious website.

This vulnerability is similar to CVE-2021-22881 and CVE-2021-22942."

Please bump to actionpack-6.1.4.2.

This requires rails 6.0.4.3 and 6.1.4.3. The x.4.2 releases were broken. Rails 5.2 is not affected.

[Comment 2 Hans de Graaff 2021-12-15 06:17:23 UTC]

Rails 6.0.4.3 and 6.1.4.3 are now available. I'll file a stable bug for actionpack and related dependencies in a few days.

Tree seems clean now, this only affects >=actionpack-6.
