CVE-2025-0674 in Communications Equipment
Summary
by MITRE • 02/07/2025
Multiple Elber products are affected by an authentication bypass vulnerability which allows unauthorized access to the password management functionality. Attackers can exploit this issue by manipulating the endpoint to overwrite any user's password within the system. This grants them unauthorized administrative access to protected areas of the application, compromising the device's system security.

This vulnerability represents a critical authentication bypass flaw affecting multiple Elber products that directly compromises the integrity of password management systems. The issue stems from insufficient input validation and improper access control mechanisms within the application's authentication framework, allowing attackers to manipulate endpoint parameters to overwrite user passwords without proper authorization. The vulnerability exists at the application logic level where the system fails to properly verify user credentials or session tokens before executing password modification operations, creating a pathway for malicious actors to escalate privileges and gain administrative access to protected system areas.
The technical implementation of this flaw demonstrates poor security design principles that align with CWE-287 which addresses improper authentication vulnerabilities. Attackers can exploit this weakness by crafting specific requests that manipulate the endpoint parameters to target any user account within the system, effectively bypassing the normal authentication flow. This type of vulnerability typically arises from inadequate parameter validation, lack of proper session management, and insufficient authorization checks that should normally prevent users from modifying accounts other than their own. The attack vector operates at the application layer where the system processes user requests without proper validation of the requesting user's permissions or identity.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass complete system compromise and potential data breaches. Once an attacker successfully overwrites a user password, they can leverage this access to navigate to administrative functions and potentially escalate privileges further. This creates a persistent threat vector that can be exploited repeatedly, as the compromised credentials can be used to maintain access to protected areas of the application. The vulnerability affects not only individual user accounts but also the overall security posture of the device, potentially exposing sensitive system information and enabling further exploitation through lateral movement within the network.
Mitigation strategies should focus on implementing robust authentication controls including proper input validation, session management, and role-based access controls that prevent unauthorized password modifications. Organizations should deploy parameter validation mechanisms that verify the authenticity of user requests and ensure that password changes can only be executed by authorized individuals with appropriate privileges. The implementation of multi-factor authentication and secure session handling can significantly reduce the attack surface, while regular security assessments and code reviews should be conducted to identify similar vulnerabilities in the system architecture. Additionally, network segmentation and monitoring solutions should be deployed to detect and alert on suspicious authentication activities that may indicate exploitation attempts, aligning with ATT&CK framework techniques related to credential access and privilege escalation.
