CVE-2022-43400 in Siveillance Video Mobile Server V2022 R2
Summary
by MITRE • 10/21/2022
A vulnerability has been identified in Siveillance Video Mobile Server V2022 R2 (All versions < V22.2a (80)). The mobile server component of affected applications improperly handles the log in for Active Directory accounts that are part of Administrators group. This could allow an unauthenticated remote attacker to access the application without a valid account.

This vulnerability resides within the Siveillance Video Mobile Server V2022 R2 software where the authentication mechanism fails to properly validate Active Directory credentials, particularly those belonging to users in the Administrators group. The flaw represents a critical authentication bypass issue that allows unauthorized remote access to the application without requiring valid credentials, creating a significant security risk for organizations relying on this video management system.
The technical implementation of this vulnerability stems from improper handling of authentication requests within the mobile server component, which fails to enforce proper credential validation for administrative accounts. This misconfiguration enables attackers to exploit the authentication flow and gain access to the application's administrative functions through a simple authentication bypass. The vulnerability affects all versions prior to V22.2a (80) and specifically targets the interaction between the mobile server and Active Directory authentication mechanisms.
From an operational perspective, this vulnerability exposes organizations to severe security implications including unauthorized access to video surveillance systems, potential data breaches, and compromise of critical infrastructure monitoring capabilities. Attackers can leverage this flaw to gain administrative privileges without proper authentication, potentially leading to complete system compromise, unauthorized video access, and modification of security settings. The remote nature of the attack means that threat actors can exploit this vulnerability from outside the network perimeter, making it particularly dangerous for organizations with remote access capabilities.
The vulnerability aligns with CWE-287 which addresses improper authentication issues, and represents a significant deviation from secure authentication practices. According to ATT&CK framework, this vulnerability maps to T1078 Valid Accounts and T1110 Brute Force techniques, as attackers can potentially exploit the authentication bypass to establish persistent access. Organizations should immediately apply the vendor-provided patch to version V22.2a (80) or higher to remediate this issue. Additional mitigations include implementing network segmentation, disabling unnecessary remote access, and monitoring authentication logs for suspicious activities. Security teams should also conduct comprehensive vulnerability assessments to identify any other systems potentially affected by similar authentication bypass vulnerabilities.
The impact of this vulnerability extends beyond simple unauthorized access, as administrators may be unaware of the compromise until significant damage has occurred. This type of flaw can facilitate lateral movement within networks and provide attackers with persistent access to critical surveillance infrastructure. Organizations should review their access control policies and ensure that administrative accounts are properly secured with strong authentication mechanisms. Regular security assessments and vulnerability scanning should be implemented to identify similar authentication weaknesses in other systems and applications.
