The actionpack ruby gem before 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6 suffers from a possible denial of service vulnerability in the Token Authentication logic in Action Controller due to a too permissive regular expression. Impacted code uses `authenticate_or_request_with_http_token` or `authenticate_with_http_token` for request authentication.
Affected: RubyGems: actionpack
There is a possible DoS vulnerability in the Token Authentication logic in Action Controller.
Versions Affected: >= 4.0.0 Not affected: < 4.0.0 Fixed Versions: 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6
Impact ------ Impacted code uses `authenticate_or_request_with_http_token` or `authenticate_with_http_token` for request authentication. Impacted code will look something like this:
``` class PostsController < ApplicationController before_action :authenticate
private
def authenticate authenticate_or_request_with_http_token do |token, options| # ... end end end ```
All users running an affected release should either upgrade or use one of the workarounds immediately.
Releases -------- The fixed releases are available at the normal locations.
Workarounds ----------- The following monkey patch placed in an initializer can be used to work around the issue:
```ruby module ActionController::HttpAuthentication::Token AUTHN_PAIR_DELIMITERS = /(?:,|;|\t)/ end ```
Patches ------- To aid users who aren't able to upgrade immediately we have provided patches for the two supported release series. They are in git-am format and consist of a single changeset.
* 5-2-http-authentication-dos.patch - Patch for 5.2 series * 6-0-http-authentication-dos.patch - Patch for 6.0 series * 6-1-http-authentication-dos.patch - Patch for 6.1 series
Please note that only the 6.1.Z, 6.0.Z, and 5.2.Z series are supported at present. Users of earlier unsupported releases are…
