Summary
by MITRE • 09/02/2026
Team Password Manager before 14.184.308 fails to enforce authentication requirements in the local account password reset flow. Unauthenticated attackers can reset local account passwords and authenticate as those users to gain unauthorized access.

The vulnerability identified in Team Password Manager prior to version 14.184.308 represents a critical failure in identity management controls, specifically within the mechanism designed for resetting local user credentials. This flaw stems from an insufficient validation process during the password reset workflow, where the application fails to enforce mandatory authentication requirements before allowing modifications to account security attributes. In a secure implementation of such systems, any operation that alters sensitive data like passwords must be preceded by rigorous verification of the requester's identity and privileges. However, in this specific version, the logic governing the local account password reset endpoint or interface does not adequately check for valid session tokens, administrative permissions, or multi-factor authentication status before proceeding with the credential update. This architectural oversight creates a direct path for unauthorized state changes within the application's user database.
From an operational perspective, this deficiency allows unauthenticated attackers to bypass standard access controls entirely. By exploiting the lack of required preconditions in the reset flow, an adversary can initiate a password change for any local account without possessing valid credentials or being logged into the system. Once the attacker successfully resets the password, they gain full authentication capabilities as that user. This effectively grants unauthorized access to all resources and data associated with the compromised account. The impact is severe because it circumvents the primary defense mechanism of the application, which relies on strong authentication to protect sensitive information stored within the password manager. Attackers can leverage this access to exfiltrate confidential credentials, manipulate existing entries, or use the privileged position to pivot further into connected systems if those accounts have elevated privileges elsewhere in the network infrastructure.
This vulnerability aligns with Common Weakness Enumeration (CWE) category CWE-287, which describes Improper Authentication, and more specifically relates to CWE-640, where a weakness allows an attacker to bypass authentication controls by exploiting flaws in the logic flow rather than breaking cryptographic algorithms. In terms of the MITRE ATT&CK framework, this behavior is indicative of T1078, Valid Accounts, as it enables attackers to obtain legitimate credentials through exploitation rather than theft or phishing. The attack vector falls under Initial Access techniques that involve abusing existing trust relationships within a system's authentication mechanisms. Because the flaw exists in the local account management subsystem, it highlights risks associated with internal service accounts and administrative interfaces that may not be protected by external identity providers like SAML or OAuth, relying instead on weaker built-in validation logic.
Mitigation strategies must prioritize immediate patching to version 14.184.308 or later, where the vendor has addressed this logical flaw by enforcing strict authentication checks prior to processing password reset requests. Until patches are applied, administrators should implement network-level controls such as firewall rules that restrict access to the Team Password Manager administrative interfaces and API endpoints from untrusted networks. Additionally, enabling multi-factor authentication for all local accounts can provide a secondary layer of defense, although it may not fully mitigate this specific flaw if the reset flow itself bypasses MFA verification steps. Security monitoring should be enhanced to detect unusual patterns in account creation or password change events, particularly those originating from unexpected IP addresses or occurring at irregular times. Regular audits of authentication logs and user activity can help identify potential exploitation attempts early, allowing for rapid incident response before significant data compromise occurs.
