CyberRota Analysis

AI-Generated

The Kimai time tracking application is vulnerable to bypassing two-factor authentication (2FA) for API access, allowing authenticated users to perform REST API operations without completing the TOTP verification. This flaw arises from the improper handling of the KIMAI_SESSION cookie, which is accepted by all API routes prior to 2FA completion. Organizations using Kimai versions prior to 2.59.0 should prioritize this vulnerability to mitigate the risk of unauthorized API access.

Original NVD Description

Kimai is an open-source time tracking application. Prior to 2.59.0, the KIMAI_SESSION cookie issued after password verification but before TOTP completion is accepted by every /api route because config/packages/security.yaml protects the API with IS_AUTHENTICATED and App\API\Authentication\ApiRequestMatcher routes an existing session through the main firewall. A Scheb TwoFactorToken satisfies that access rule, and App\Voter\ApiVoter grants API access to its User, allowing an attacker with a valid account password to use authenticated REST API operations without entering the second factor even though web routes remain blocked. This issue is fixed in version 2.59.0.
