Devise-Two-Factor Authentication Uses Insufficient Default OTP Shared Secret Length

Summary Under the default configuration, Devise-Two-Factor version = 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...

Devise-Two-Factor 安全漏洞

Devise-Two-Factor is a minimalist extension of Devise to the Devise-Two-Factor open source. It is used to provide support for two-factor authentication via TOTP schemes. A security vulnerability exists in Devise-Two-Factor versions 2.2.0 and earlier and 6.0.0 and earlier, which stems from an...

CVE-2024-8796: Insufficient Entropy

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...

GHSA-CHCR-X7HC-8FP8 Devise-Two-Factor vulnerable to brute force attacks

Advisory withdrawn The backing CVE has been rejected Devise-Two-Factor does not throttle or otherwise restrict login attempts at the server by default. When combined with the Time-based One Time Password algorithm's TOTP inherent entropy limitations, it's possible for an attacker to bypass the 2F...

Brute Force Attack

devise-two-factor is vulnerable to Brute Force Attack. The vulnerability is due to a lack of attempt restriction of login attempts in Devise-Two-Factor. This issue, when combined with the inherent entropy limitations of the Time-based One-Time Password TOTP algorithm, This allows an attacker to...

Devise-Two-Factor vulnerable to brute force attacks

Devise-Two-Factor does not throttle or otherwise restrict login attempts at the server by default. When combined with the Time-based One Time Password algorithm's TOTP inherent entropy limitations, it's possible for an attacker to bypass the 2FA mechanism through brute-force attacks. Impact If a...

Devise-Two-Factor does not throttle or otherwise restrict login attempts at the server by default. When combined with the Time-based One Time Password algorithm's TOTP inherent entropy limitations, it's possible for an attacker to bypass the 2FA mechanism through brute-force attacks...

CVE-2024-0227

Devise-Two-Factor is vulnerable to brute-force attacks due to no throttling of login attempts by default, allowing an attacker to test possible TOTP codes if username/password are compromised. Documents from RubySec and GitHub advisories describe an attacker bypassing 2FA by brute-forcing TOTP, w...

Time-Based One-Time Password Algorithm (TOPT) Replay Attack

devise-two-factor is vulnerable to time-based one-time password algorithm TOPT replay attacks. A remote attacker is able to reuse the one-time-password immediately trailing the interval in order to gain access to the victim's account given that the attacker already knows the victim's credentials...
