CVE-2023-28809 in DS-K1T341AXX
Summary
by MITRE • 06/15/2023
Some access control products are vulnerable to a session hijacking attack because the product does not update the session ID after a user successfully logs in. To exploit the vulnerability, attackers have to request the session ID at the same time as a valid user logs in, and gain device operation permissions by forging the IP and session ID of an authenticated user.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

This vulnerability represents a critical session management flaw that directly undermines the security posture of access control systems. The issue stems from improper session handling where the system fails to regenerate session identifiers upon successful authentication, creating a persistent security weakness that can be exploited by malicious actors. According to CWE-384, this constitutes a session fixation vulnerability where the same session token remains active before and after authentication, allowing attackers to maintain unauthorized access to protected resources. The vulnerability affects authentication mechanisms that do not implement proper session regeneration protocols, leaving systems susceptible to session hijacking attacks that can be executed with relatively simple techniques.
The technical exploitation of this vulnerability requires attackers to synchronize their actions with a legitimate user's login process to capture valid session tokens. This timing attack approach leverages the window of opportunity that exists between when a user authenticates and when the system should ideally invalidate the previous session identifier. Attackers can forge both the IP address and session ID of authenticated users, effectively impersonating legitimate users and gaining unauthorized operational permissions within the access control system. The attack vector demonstrates a fundamental flaw in the system's session lifecycle management, where session identifiers are not properly rotated or invalidated during the authentication transition process.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass complete compromise of access control mechanisms. Once exploited, attackers can perform any actions available to authenticated users, potentially gaining administrative privileges or access to restricted areas within the controlled environment. This vulnerability particularly affects physical security systems where access control products manage entry points, creating opportunities for attackers to bypass physical security measures and gain unauthorized physical access to facilities. The implications are severe as it undermines the core security principle of authentication and authorization, allowing attackers to maintain persistent access without detection.
Mitigation strategies must focus on implementing robust session management protocols that automatically regenerate session identifiers upon successful authentication. Organizations should ensure their access control systems follow the principle of least privilege and implement proper session invalidation mechanisms that occur immediately upon user authentication. Security measures should include mandatory session regeneration after login, session timeout mechanisms, and monitoring for suspicious session activity patterns. According to ATT&CK framework, this vulnerability maps to T1566.001 (Phishing) and T1078.004 (Valid Accounts) as attackers may exploit this weakness to establish persistent access using stolen session tokens. System administrators should also implement network monitoring solutions to detect anomalous session behavior and ensure that all access control products are regularly updated to address known session management vulnerabilities.
