CVE-2016-6566 in eTRAKiT3
Summary
by MITRE
The valueAsString parameter inside the JSON payload contained by the ucLogin_txtLoginId_ClientStat POST parameter of the Sungard eTRAKiT3 software version 3.2.1.17 is not properly validated. An unauthenticated remote attacker may be able to modify the POST request and insert a SQL query which may then be executed by the backend server. eTRAKiT 3.2.1.17 was tested, but other versions may also be vulnerable.

The vulnerability identified as CVE-2016-6566 resides within the Sungard eTRAKiT3 software version 3.2.1.17, specifically within the handling of the ucLogin_txtLoginId_ClientStat POST parameter. This flaw represents a critical SQL injection vulnerability that stems from insufficient validation of the valueAsString parameter within the JSON payload structure. The vulnerability occurs during the authentication process where user input is not properly sanitized before being processed by the backend database server. The attack vector is particularly dangerous because it allows unauthenticated remote attackers to manipulate the POST request and inject malicious SQL commands directly into the system.
The technical implementation of this vulnerability aligns with CWE-89, which describes improper neutralization of special elements used in SQL commands, and represents a classic SQL injection flaw that operates at the application layer. The flaw manifests when the application accepts user-provided data through the ucLogin_txtLoginId_ClientStat parameter without adequate input validation or sanitization mechanisms. The JSON payload structure creates an additional attack surface where malicious actors can construct specially crafted requests that bypass normal input filtering. The vulnerability is particularly concerning because it allows for arbitrary SQL command execution, potentially enabling attackers to extract sensitive data, modify database contents, or even escalate privileges within the affected system.
The operational impact of this vulnerability extends far beyond simple data corruption or unauthorized access. Remote attackers can leverage this flaw to gain complete control over the backend database, potentially accessing sensitive user information, financial data, or confidential organizational records. The vulnerability affects the authentication mechanism itself, meaning that successful exploitation could allow attackers to bypass authentication entirely or manipulate user accounts. Given that the software is used for tracking and management purposes, the compromise of database integrity could lead to significant operational disruptions and regulatory compliance violations. The lack of authentication requirements for exploitation makes this vulnerability particularly dangerous in environments where the application is exposed to untrusted networks.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The most effective immediate solution involves implementing proper input validation and sanitization for all user-provided data, particularly within the JSON payload structures. Organizations should deploy web application firewalls to filter malicious requests and implement proper parameterized queries to prevent SQL injection attacks. The fix should include comprehensive input validation that rejects any SQL-specific characters or sequences within the valueAsString parameter. Additionally, implementing proper access controls and network segmentation can limit the attack surface. The vulnerability demonstrates the importance of following secure coding practices and adhering to OWASP Top Ten security guidelines, particularly those addressing injection flaws and authentication mechanisms. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other application components and ensure that proper security controls are in place across the entire system architecture.
