CVE-2024-0580 in Sinergia
Summary
by MITRE • 01/18/2024
Omission of user-controlled key authorization in the IDMSistemas platform, affecting the QSige product. This vulnerability allows an attacker to extract sensitive information from the API by making a request to the parameter '/qsige.locator/quotePrevious/centers/X', where X supports values 1,2,3, etc.

The CVE-2024-0580 vulnerability represents a critical authorization flaw within the IDMSistemas QSige platform that undermines the security controls protecting sensitive data access. This vulnerability exists in the API endpoint structure where the system fails to properly validate user credentials or authorization tokens when processing requests to the quotePrevious/centers endpoint. The affected parameter accepts numeric values from 1 to 3, indicating that the system likely manages multiple organizational units or data centers, but lacks proper access control mechanisms to ensure users can only access data they are authorized to view. This omission creates a path for unauthorized information disclosure that directly violates fundamental security principles of least privilege and access control enforcement. The vulnerability aligns with CWE-285, which addresses improper authorization in software systems, and represents a classic case of insufficient access control validation.
The technical exploitation of this vulnerability occurs through straightforward API manipulation where an attacker can enumerate different center values to access data belonging to other organizational units or users. The system's failure to implement proper authentication checks before processing requests means that any user with knowledge of the API structure can potentially access sensitive information from multiple centers simply by incrementing the numeric parameter value. This type of vulnerability demonstrates a lack of input validation and authorization enforcement at the application level, creating a direct pathway for information leakage. The attack pattern corresponds to ATT&CK technique T1213.002, which involves accessing data through API endpoints, and represents a common weakness in web application security where proper access control boundaries are not enforced.
The operational impact of this vulnerability extends beyond simple data exposure to potentially compromise the entire data integrity and confidentiality of the QSige platform. Organizations using this system may experience unauthorized access to competitive pricing information, customer data, or other proprietary business information that could be exploited for financial gain or competitive advantage. The vulnerability affects the core functionality of the platform's data management system, potentially exposing sensitive business intelligence to unauthorized parties. This weakness could lead to regulatory compliance violations under data protection frameworks such as GDPR or other privacy regulations that mandate proper access controls for sensitive information. The vulnerability also represents a significant risk to business operations as it could enable competitors to gain insights into pricing strategies, customer bases, or operational details that should remain confidential.
Mitigation strategies for CVE-2024-0580 must focus on implementing robust access control mechanisms that validate user authorization before processing any requests to the quotePrevious/centers endpoint. Organizations should immediately implement proper authentication checks that verify user credentials and authorization levels before allowing access to different center values. The system should enforce role-based access control where users can only access data centers relevant to their assigned roles or organizational units. Additionally, implementing proper input validation and parameter sanitization will prevent attackers from enumerating different center values without proper authorization. Security measures should include logging and monitoring of API access patterns to detect unauthorized access attempts, and implementing rate limiting to prevent automated enumeration attacks. Organizations should also consider implementing API gateways with built-in authorization controls and ensure that all API endpoints undergo proper security testing including authorization testing as part of their development lifecycle. The fix should align with security standards such as NIST SP 800-53 and ISO 27001 requirements for access control and information security management.
