The SQL injection vulnerability in risesoft-y9 Digital-Infrastructure arises from improper input sanitization in the REST Authenticate Endpoint, specifically within the `Y9PlatformUtil.java` file. Attackers can exploit this by crafting malicious SQL payloads in authentication requests sent to the vulnerable endpoint. These payloads are directly concatenated into SQL queries without adequate validation or parameterization, allowing arbitrary SQL command execution on the backend database. The flaw permits remote attackers to manipulate database operations, potentially leading to unauthorized data access, authentication bypass, data corruption, or full system compromise. Given the public availability of the exploit, attackers can leverage known techniques to inject SQL commands through parameters handled by the affected function. The vulnerability is particularly critical as it targets an authentication component, which could enable complete takeover of the digital infrastructure platform. The lack of response from the project maintainers exacerbates the risk, leaving systems running versions up to 9.6.7 exposed to active attacks.
Platform: risesoft-y9 Digital-Infrastructure
Version: <=9.7.0-M5
Vulnerability: SQL injection
Severity: Moderate
date: Jan 17, 2026
Prediction: Q1 2026
What Undercode Say:
Analytics
curl -X POST http://target:port/authenticate -H "Content-Type: application/json" -d '{"user":"admin", "password":"' OR '1'='1"}'
sqlmap -u "http://target:port/authenticate" --data="user=admin&password=test" --risk=3 --level=5
// Example vulnerable code snippet from Y9PlatformUtil.java String query = "SELECT FROM users WHERE username = '" + userInput + "' AND password = '" + passInput + "'"; // Mitigation: Use prepared statements String query = "SELECT FROM users WHERE username = ? AND password = ?"; PreparedStatement stmt = connection.prepareStatement(query); stmt.setString(1, userInput); stmt.setString(2, passInput);
How Exploit:
Remote attackers send crafted HTTP POST requests with SQL injection payloads in the authentication parameters to the REST endpoint, executing arbitrary database commands.
Protection from this CVE
Apply input validation, use parameterized queries or prepared statements, deploy WAF rules, and restrict database permissions.
Impact:
Data breach, authentication bypass, system compromise, remote code execution.
