GSD-2021-41819

Vulnerability from gsd - Updated: 2021-11-24 00:00

Details

The old versions of `CGI::Cookie.parse` applied URL decoding to cookie names. An attacker could exploit this vulnerability to spoof security prefixes in cookie names, which may be able to trick a vulnerable application. By this fix, `CGI::Cookie.parse` no longer decodes cookie names. Note that this is an incompatibility if cookie names that you are using include non-alphanumeric characters that are URL-encoded. This is the same issue of CVE-2020-8184. If you are using Ruby 2.7 or 3.0: * Please update the cgi gem to version 0.3.1, 0.2,1, and 0.1,1 or later. You can use `gem update cgi` to update it. If you are using bundler, please add `gem "cgi", ">= 0.3.1"`` to your `Gemfile`. * Alternatively, please update Ruby to 2.7.5 or 3.0.3. If you are using Ruby 2.6: * Please update Ruby to 2.6.9. You cannot use `gem update cgi` for Ruby 2.6 or prior.

Note that\nthis is an incompatibility if cookie names that you are using include\nnon-alphanumeric characters that are URL-encoded.\n\nThis is the same issue of CVE-2020-8184.\n\nIf you are using Ruby 2.7 or 3.0:\n\n* Please update the cgi gem to version 0.3.1, 0.2,1, and 0.1,1 or later. You\n  can use `gem update cgi` to update it. If you are using bundler, please add\n  `gem \"cgi\", \"\u003e= 0.3.1\"`` to your `Gemfile`.\n* Alternatively, please update Ruby to 2.7.5 or 3.0.3.\n\nIf you are using Ruby 2.6:\n\n* Please update Ruby to 2.6.9.
