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.
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)
</tr></table>
Carefully crafted input can cause a DoS via the regular expressions used
for validating the money format in the PostgreSQL adapter. This patch
fixes the regexp.
