CVE-2024-26262 in Uniweb
Summary
by MITRE • 02/15/2024
EBM Technologies Uniweb/SoliPACS WebServer's query functionality lacks proper restrictions of user input, allowing remote attackers authenticated as regular user to inject SQL commands for reading, modifying, and deleting database records, as well as executing system commands. Attackers may even leverage the dbo privilege in the database for privilege escalation, elevating their privileges to administrator .

This vulnerability resides within the EBM Technologies Uniweb/SoliPACS WebServer platform where the query functionality fails to implement adequate input validation mechanisms. The absence of proper sanitization and restriction of user-provided data creates a critical security gap that enables authenticated regular users to perform unauthorized database operations through SQL injection attacks. The flaw exists at the application layer where user input is directly incorporated into database queries without proper escaping or parameterization techniques, violating fundamental security principles outlined in cwe-89 and cwe-77. The vulnerability affects the web server component that handles database interactions, making it a prime target for attackers seeking to exploit weak input handling practices.
The technical implementation of this vulnerability allows attackers to manipulate database queries through crafted input parameters that are processed by the web application. When a regular user submits a query containing malicious SQL payloads, the application fails to properly validate or sanitize these inputs before incorporating them into backend database commands. This enables attackers to inject arbitrary SQL commands that can read sensitive database records, modify existing data, delete critical information, or even execute system commands on the underlying database server. The attack surface is particularly concerning because the application appears to grant database access permissions that include dbo privileges, which provides attackers with elevated database rights. This configuration allows for privilege escalation from regular user status to administrator level access, as the database user account likely possesses sufficient permissions to manipulate system-level functions and access restricted database objects.
The operational impact of this vulnerability extends beyond simple data compromise to encompass full system control capabilities. Attackers can leverage the SQL injection to extract confidential patient records, modify medical data, or delete critical information within the SoliPACS system, potentially causing serious harm to healthcare operations. The ability to execute system commands through database access represents a severe escalation opportunity that could lead to complete system compromise. The vulnerability affects organizations using EBM Technologies Uniweb/SoliPACS solutions, particularly healthcare facilities that rely on these systems for medical imaging and patient data management. This threat aligns with attack patterns documented in the attack tactic of privilege escalation and data manipulation within the MITRE ATT&CK framework, specifically targeting the database access and command execution capabilities.
Mitigation strategies should focus on implementing comprehensive input validation and parameterized query execution throughout the application codebase. The recommended approach includes enforcing strict input sanitization, utilizing prepared statements with parameterized queries, and implementing proper access controls that limit database user privileges to the minimum required for application functionality. Organizations should also consider implementing web application firewalls to detect and block suspicious SQL injection patterns, while establishing regular security code reviews and penetration testing procedures. The database configuration should be audited to ensure that regular application users do not possess unnecessary dbo privileges, and privilege escalation paths should be carefully evaluated and restricted. Additionally, implementing proper logging and monitoring mechanisms can help detect unauthorized database access attempts and provide early warning of potential exploitation activities. This vulnerability demonstrates the critical importance of following secure coding practices and adhering to the principle of least privilege in database access control, as outlined in various cybersecurity frameworks including nist csf and iso 27001 standards.
