Attack Chain

1. An attacker identifies an Oinone Pamirs instance running a version equal to or below 7.2.0 with the vulnerable queryListByWrapper interface exposed.
2. The attacker crafts a malicious HTTP request targeting the queryListByWrapper interface.
3. The request includes specially crafted input designed to inject SQL commands into the RSQLToSQLNodeConnector.makeVariable function.
4. The application processes the malicious input without proper sanitization.
5. The injected SQL commands are executed against the underlying database.
6. The attacker gains unauthorized access to sensitive data stored in the database.
7. The attacker may modify or delete data, potentially leading to data corruption or denial of service.
8. The attacker could potentially use the database as a pivot point to compromise other systems on the network.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-8734) can lead to unauthorized access to sensitive information, data manipulation, and potential compromise of the underlying database server. Given the presence of publicly available exploits, organizations using vulnerable versions of Oinone Pamirs are at significant risk. The impact could range from data breaches and financial loss to reputational damage and disruption of services.

Recommendation

• Apply appropriate input validation and sanitization techniques to mitigate SQL injection vulnerabilities, referencing CWE-89.
• Deploy the Sigma rule Detect CVE-2026-8734 Exploitation — SQL Injection in Oinone Pamirs to identify potential exploitation attempts.
• Monitor web server logs for suspicious requests targeting the queryListByWrapper interface (logsource: webserver).
• Review and restrict database access privileges to minimize the impact of potential SQL injection attacks.
