CVE-2025-41078 in Documents
Summary
by MITRE • 01/12/2026
Weaknesses in the authorization mechanisms of Viafirma Documents v3.7.129 allow an authenticated user without privileges to list and access other user data, use user creation, modification, and deletion features, and escalate privileges by impersonating other users of the application in the generation and signing of documents.

The vulnerability identified as CVE-2025-41078 represents a critical authorization flaw within Viafirma Documents version 3.7.129 that fundamentally undermines the application's security model. This weakness manifests as a failure in access control mechanisms that should normally prevent unauthorized users from accessing sensitive data or performing administrative functions. The vulnerability affects the core authorization framework that governs user permissions and privileges within the document management system, creating a pathway for authenticated but unprivileged users to bypass intended security boundaries.
The technical implementation of this authorization bypass stems from insufficient validation of user roles and permissions during critical operations within the application's backend services. Attackers can exploit this flaw by manipulating API calls or web interface interactions to enumerate user accounts and access data that should be restricted to specific user roles. The vulnerability specifically enables unauthorized access to user data through list operations that should require elevated privileges, while simultaneously providing the capability to perform user management functions including creation, modification, and deletion of accounts. This represents a classic case of insufficient authorization checks as classified under CWE-285, where the application fails to properly verify that users have the necessary permissions before executing privileged operations.
The operational impact of this vulnerability extends far beyond simple data exposure, as it creates a complete escalation path for malicious actors to assume the identity of other users within the system. Through privilege escalation capabilities, attackers can impersonate legitimate users to generate and sign documents, effectively bypassing all document authentication and integrity controls that the application is designed to enforce. This allows for potential fraud, unauthorized document modifications, and complete compromise of the document signing workflow that Viafirma Documents is intended to secure. The implications are particularly severe in enterprise environments where document signing and authentication are critical for legal and compliance purposes.
Mitigation strategies for this vulnerability must address the fundamental authorization flaws within the application's access control implementation. Organizations should immediately implement role-based access controls that enforce strict permission boundaries for all user operations, ensuring that each action performed within the system is validated against the authenticated user's actual privileges. The application should be updated to version 3.7.130 or later, which contains patches addressing the authorization bypass mechanisms. Security teams should conduct comprehensive access control reviews to identify and remediate similar weaknesses in other parts of the application, while implementing monitoring solutions to detect unauthorized privilege escalation attempts. Additionally, organizations should consider implementing multi-factor authentication and session management improvements to reduce the impact of credential compromise in case of further vulnerabilities. This vulnerability aligns with ATT&CK technique T1078 which covers valid accounts and privilege escalation through unauthorized access to system resources, making it a critical target for immediate remediation.
