CVE-2024-8796

Published: Sep 17, 2024

Modified: Sep 20, 2024

PUBLISHED

CVSS v3.1

5.3

MEDIUM

Description

Under the default configuration, Devise-Two-Factor versions >= 2.2.0 & < 6.0.0 generate TOTP shared secrets that are 120 bits instead of the 128-bit minimum defined by RFC 4226. Using a shared secret shorter than the minimum to generate a multi-factor authentication code could make it easier for an attacker to guess the shared secret and generate valid TOTP codes.
