CVE-2024-45789 in Mutual Fund Distribution Product
Summary
by MITRE • 09/11/2024
This vulnerability exists in Reedos aiM-Star version 2.0.1 due to improper validation of the ‘mode’ parameter in the API endpoint used during the registration process. An authenticated remote attacker could exploit this vulnerability by manipulating parameter in the API request body on the vulnerable application.
Successful exploitation of this vulnerability could allow the attacker to bypass certain constraints in the registration process leading to creation of multiple accounts.

The vulnerability identified as CVE-2024-45789 affects the Reedos aiM-Star version 2.0.1 system where insufficient input validation occurs within the registration API endpoint. This flaw resides in the handling of the 'mode' parameter which is processed during user account creation procedures. The vulnerability represents a classic example of improper input validation that allows attackers to manipulate application behavior through crafted API requests. The issue manifests when the system fails to properly validate or sanitize the mode parameter value, creating an avenue for unauthorized manipulation of the registration workflow. This type of vulnerability falls under the CWE-20 category, which specifically addresses improper input validation as a fundamental weakness in software security design. The attack vector requires an authenticated remote attacker who can leverage existing credentials to send manipulated requests to the vulnerable application's API endpoints.
The technical exploitation of this vulnerability enables an authenticated attacker to manipulate the mode parameter within API request bodies during the registration process. This manipulation allows the attacker to bypass intended constraints and restrictions that normally govern account creation procedures. When the system processes the modified mode parameter without proper validation, it permits the creation of multiple user accounts beyond what would normally be permitted under standard registration protocols. The flaw essentially undermines the application's access control mechanisms by allowing unauthorized account proliferation, which can lead to various downstream security implications. The vulnerability demonstrates how parameter manipulation can circumvent business logic controls that are meant to enforce registration policies and maintain system integrity. This weakness essentially transforms the registration process from a controlled environment into one where malicious actors can manipulate account creation parameters to their advantage.
The operational impact of CVE-2024-45789 extends beyond simple account creation abuse and can enable significant security compromise within the affected system. An attacker who successfully exploits this vulnerability can potentially create multiple accounts to facilitate further attacks such as denial of service through account exhaustion, credential stuffing attacks, or social engineering campaigns that leverage the increased account density. The ability to bypass registration constraints opens possibilities for privilege escalation and unauthorized access to system resources that may be restricted to legitimate users. This vulnerability can also undermine audit trails and user management systems since the normal account creation logging and monitoring mechanisms become ineffective when attackers can manipulate registration parameters. From a compliance standpoint, this vulnerability may result in violations of data protection regulations that require proper access controls and user authentication mechanisms. The impact aligns with ATT&CK technique T1078 which covers valid accounts usage and can be leveraged for persistence and privilege escalation within the system.
Mitigation strategies for CVE-2024-45789 should focus on implementing robust input validation and parameter sanitization within the registration API endpoint. The system must enforce strict validation of the mode parameter against predefined acceptable values and reject any requests containing unexpected or malformed parameter values. Implementing proper access control mechanisms and rate limiting for account creation requests can prevent abuse of the registration process. The application should also implement comprehensive logging and monitoring of registration activities to detect anomalous account creation patterns that may indicate exploitation attempts. Security patches should be applied immediately to update the Reedos aiM-Star version to a patched release that addresses the parameter validation issue. Additionally, the system should employ proper session management and authentication controls to ensure that only authorized users can access registration endpoints. Network segmentation and API gateway controls can provide additional layers of protection by limiting access to registration endpoints and monitoring traffic patterns for suspicious activities. Regular security testing including penetration testing and vulnerability scanning should be conducted to identify and remediate similar validation weaknesses in other system components.
