CVE-2015-7225 (opens in a new tab)How to fix?
Upgrade Debian:11 ruby-devise-two-factor to version 2.0.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby-devise-two-factor package and not the ruby-devise-two-factor package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
Tinfoil Devise-two-factor before 2.0.0 does not strictly follow section 5.2 of RFC 6238 and does not "burn" a successfully validated one-time password (aka OTP), which allows remote or physically proximate attackers with a target user's login credentials to log in as said user by obtaining the OTP through performing a man-in-the-middle attack between the provider and verifier, or shoulder surfing, and replaying the OTP in the current time-step.
