CVE-2024-5277 in lunary
Summary
by MITRE • 06/06/2024
In lunary-ai/lunary version 1.2.4, a vulnerability exists in the password recovery mechanism where the reset password token is not invalidated after use. This allows an attacker who compromises the recovery token to repeatedly change the password of a victim's account. The issue lies in the backend's handling of the reset password process, where the token, once used, is not discarded or invalidated, enabling its reuse. This vulnerability could lead to unauthorized account access if an attacker obtains the recovery token.

The vulnerability identified in lunary-ai/lunary version 1.2.4 represents a critical weakness in the password recovery system that directly impacts account security and user privacy. This flaw resides within the backend implementation of the password reset functionality, where the system fails to properly invalidate reset tokens after their initial use. The vulnerability is classified as a weakness in authentication mechanisms and falls under the broader category of credential management failures that can be mapped to CWE-613, which addresses insufficient session expiration or invalidation of authentication tokens. The issue creates a persistent security risk where compromised tokens can be reused indefinitely, undermining the fundamental security principle that authentication tokens should be single-use or immediately invalidated upon consumption.
The technical implementation of this vulnerability stems from improper state management within the password recovery workflow. When a user requests a password reset, the system generates a unique token and sends it to the user's registered email address. However, upon successful token validation and password change, the system does not remove or mark the token as invalid in its database or token storage mechanism. This oversight allows an attacker who has obtained the reset token through various means such as email interception, compromised user credentials, or other attack vectors to repeatedly submit the same token to change the victim's password multiple times. The backend service continues to accept the token as valid, creating a window of opportunity for unauthorized account takeover that extends beyond the intended single-use period.
The operational impact of this vulnerability extends beyond simple account compromise to encompass broader security implications for the entire user base and system infrastructure. An attacker with access to a single reset token can maintain persistent unauthorized access to victim accounts, potentially leading to data theft, service disruption, or further exploitation of compromised accounts. This vulnerability directly aligns with attack patterns described in the MITRE ATT&CK framework under T1531 for Account Access Removal and T1078 for Valid Accounts, as it enables unauthorized access to legitimate user accounts without detection. The vulnerability also creates a significant risk for organizations using this software, as it may expose sensitive user data and compromise the trust relationship between users and service providers, potentially leading to regulatory compliance issues and reputational damage.
Mitigation strategies for this vulnerability should focus on implementing proper token lifecycle management within the password recovery system. The most effective approach involves immediately invalidating reset tokens upon successful use by either removing them from the database, marking them as consumed, or implementing a time-based expiration mechanism that automatically invalidates tokens after a predetermined window. Organizations should also consider implementing additional security measures such as rate limiting on password reset requests, requiring secondary authentication factors, and monitoring for suspicious account activity patterns. The solution should be implemented in accordance with security best practices outlined in OWASP Top Ten and NIST Cybersecurity Framework, ensuring that authentication tokens follow the principle of least privilege and are handled with appropriate security controls. Regular security auditing and penetration testing should be conducted to verify that token invalidation mechanisms are functioning correctly and that no similar vulnerabilities exist in related authentication systems.
