CVE-2020-8162
GHSA-m42x-37p3-fv5w
Circumvention of file size limits in ActiveStorage There is a vulnerability in ActiveStorage's S3 adapter that allows the Content-Length of a direct file upload to be modified by an end user. Versions Affected: rails < 5.2.4.2, rails < 6.0.3.1 Not affected: Applications that do not use the direct upload functionality of the ActiveStorage S3 adapter. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1 Impact ------ Utilizing this vulnerability, an attacker can control the Content-Length of an S3 direct upload URL without receiving a new signature from the server. This could be used to bypass controls in place on the server to limit upload size. Workarounds ----------- This is a low-severity security issue. As such, no workaround is necessarily until such time as the application can be upgraded. There are no reported fixed by versions.

Possible Strong Parameters Bypass in ActionPack There is a strong parameters bypass vector in ActionPack. Versions Affected: rails <= 6.0.3 Not affected: rails < 4.0.0 Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1 Impact ------ In some cases user supplied information can be inadvertently leaked from Strong Parameters. Specifically the return value of `each`, or `each_value`, or `each_pair` will return the underlying "untrusted" hash of data that was read from the parameters. Applications that use this return value may be inadvertently use untrusted user input. Impacted code will look something like this: ``` def update # Attacker has included the parameter: `{ is_admin: true }` User.update(clean_up_params) end def clean_up_params params.each { |k, v| SomeModel.check(v) if k == :name } end ``` Note the mistaken use of `each` in the `clean_up_params` method in the above example. Workarounds ----------- Do not use the return values of `each`, `each_value`, or `each_pair` in your application. There are no reported fixed by versions.

GHSA-jp5v-5gx4-jmj9
Ability to forge per-form CSRF tokens given a global CSRF token It is possible to possible to, given a global CSRF token such as the one present in the authenticity_token meta tag, forge a per-form CSRF token for any action for that session. Versions Affected: rails < 5.2.5, rails < 6.0.4 Not affected: Applications without existing HTML injection vulnerabilities. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1 Impact ------ Given the ability to extract the global CSRF token, an attacker would be able to construct a per-form CSRF token for that session. Workarounds ----------- This is a low-severity security issue. As such, no workaround is necessarily until such time as the application can be upgraded. There are no reported fixed by versions.

Untrusted users able to run pending migrations in production There is a vulnerability in versions of Rails prior to 6.0.3.2 that allowed an untrusted user to run any pending migrations on a Rails app running in production. This vulnerability has been assigned the CVE identifier CVE-2020-8185. Versions Affected: 6.0.0 < rails < 6.0.3.2 Not affected: Applications with `config.action_dispatch.show_exceptions = false` (this is not a default setting in production) Fixed Versions: rails >= 6.0.3.2 Impact ------ Using this issue, an attacker would be able to execute any migrations that are pending for a Rails app running in production mode. It is important to note that an attacker is limited to running migrations the application developer has already defined in their application and ones that have not already ran. Workarounds ----------- Until such time as the patch can be applied, application developers should disable the ActionDispatch middleware in their production environment via a line such as this one in their config/environment/production.rb: `config.middleware.delete ActionDispatch::ActionableExceptions` There are no reported fixed by versions.

Session fixation vulnerability via Set-Cookie headers The package rest-client in `abstract_response.rb` improperly handles `Set-Cookie` headers on HTTP redirection responses. Any cookies will be forwarded to the redirection target regardless of domain, path, or expiration. If you control a redirection source, you can cause rest-client to perform a request to any third-party domain with cookies of your choosing, which may be useful in performing a session fixation attack. If you control a redirection target, you can steal any cookies set by the third-party redirection request. There are no reported fixed by versions.

GHSA-2p68-f74v-9wc6
Potentially unintended unmarshalling of user-provided objects in MemCacheStore and RedisCacheStore There is potentially unexpected behaviour in the MemCacheStore and RedisCacheStore where, when untrusted user input is written to the cache store using the `raw: true` parameter, re-reading the result from the cache can evaluate the user input as a Marshalled object instead of plain text. Vulnerable code looks like: ``` data = cache.fetch("demo", raw: true) { untrusted_string } ``` Versions Affected: rails < 5.2.5, rails < 6.0.4 Not affected: Applications not using MemCacheStore or RedisCacheStore. Applications that do not use the `raw` option when storing untrusted user input. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1 Impact ------ Unmarshalling of untrusted user input can have impact up to and including RCE. At a minimum, this vulnerability allows an attacker to inject untrusted Ruby objects into a web application. In addition to upgrading to the latest versions of Rails, developers should ensure that whenever they are calling `Rails.cache.fetch` they are using consistent values of the `raw` parameter for both reading and writing, especially in the case of the RedisCacheStore which does not, prior to these changes, detect if data was serialized using the raw option upon deserialization. Workarounds ----------- It is recommended that application developers apply the suggested patch or upgrade to the latest release as soon as possible. If this is not possible, we recommend ensuring that all user-provided strings cached using the `raw` argument should be double-checked to ensure that they conform to the expected format. There are no reported fixed by versions.

Possible information leak / session hijack vulnerability There's a possible information leak / session hijack vulnerability in Rack. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are usually stored and indexed in a database that uses some kind of scheme for speeding up lookups of that session id. By carefully measuring the amount of time it takes to look up a session, an attacker may be able to find a valid session id and hijack the session. The session id itself may be generated randomly, but the way the session is indexed by the backing store does not use a secure comparison. Impact: The session id stored in a cookie is the same id that is used when querying the backing session storage engine. Most storage mechanisms (for example a database) use some sort of indexing in order to speed up the lookup of that id. By carefully timing requests and session lookup failures, an attacker may be able to perform a timing attack to determine an existing session id and hijack that session. There are no reported fixed by versions.

CSRF Vulnerability in rails-ujs There is an vulnerability in rails-ujs that allows attackers to send CSRF tokens to wrong domains. Versions Affected: rails <= 6.0.3 Not affected: Applications which don't use rails-ujs. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1 Impact ------ This is a regression of CVE-2015-1840. In the scenario where an attacker might be able to control the href attribute of an anchor tag or the action attribute of a form tag that will trigger a POST action, the attacker can set the href or action to a cross-origin URL, and the CSRF token will be sent. Workarounds ----------- To work around this problem, change code that allows users to control the href attribute of an anchor tag or the action attribute of a form tag to filter the user parameters. For example, code like this: link_to params to code like this: link_to filtered_params def filtered_params # Filter just the parameters that you trust end There are no reported fixed by versions.

Potential XSS vulnerability in Action View There is a potential Cross-Site Scripting (XSS) vulnerability in Action View's translation helpers. Views that allow the user to control the default (not found) value of the `t` and `translate` helpers could be susceptible to XSS attacks. Impact ------ When an HTML-unsafe string is passed as the default for a missing translation key [named `html` or ending in `_html`](https://guides.rubyonrails.org/i18n.html#using-safe-html-translations), the default string is incorrectly marked as HTML-safe and not escaped. Vulnerable code may look like the following examples: ```erb <%# The welcome_html translation is not defined for the current locale: %> <%= t("welcome_html", default: untrusted_user_controlled_string) %> <%# Neither the title.html translation nor the missing.html translation is defined for the current locale: %> <%= t("title.html", default: [:"missing.html", untrusted_user_controlled_string]) %> ``` Workarounds ----------- Impacted users who can’t upgrade to a patched Rails version can avoid this issue by manually escaping default translations with the `html_escape` helper (aliased as `h`): ```erb <%= t("welcome_html", default: h(untrusted_user_controlled_string)) %> ``` There are no reported fixed by versions.
