CVE-2024-46542

Executive Summary

CVE-2024-46542 is a high-severity SQL injection vulnerability affecting Veritas (Arctera) Data Insight versions prior to 7.1.1. An authenticated Application Administrator can exploit this flaw to execute arbitrary SQL commands against the backend database, potentially leading to data exfiltration, privilege escalation, or complete compromise of the Data Insight application. The vulnerability has a CVSS score of 6.5 (Medium) but carries significant risk due to the high privileges required and the sensitive nature of data managed by Data Insight. No public proof-of-concept (PoC) or exploit code has been released as of this analysis. The vendor has released a patched version (7.1.1) to address the issue.

Supply Chain & Package Security

This vulnerability is not related to an open-source package manager (NPM, PyPI, Go, Ruby). It affects a proprietary enterprise software product (Veritas Data Insight). Therefore, supply chain security considerations are limited to ensuring the integrity of the vendor-provided update and verifying its digital signature before deployment.

CVSS Breakdown & Threat Level

• CVSS Score: 6.5 (Medium)
• Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
• Attack Vector (AV): Network – The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC): Low – No special conditions or complex attack sequences are required.
• Privileges Required (PR): High – An attacker must have Application Administrator credentials.
• User Interaction (UI): None – No user action is needed beyond the attacker’s own actions.
• Scope (S): Unchanged – The exploit cannot affect resources beyond the vulnerable component.
• Confidentiality (C): High – Full database contents could be read.
• Integrity (I): High – Database records could be modified or deleted.
• Availability (A): High – Database operations could be disrupted or the service crashed.

Threat Level: Elevated. While the CVSS score is Medium, the impact is High across all three security objectives. The requirement for high privileges reduces the likelihood of widespread exploitation, but insider threats or credential compromise scenarios are realistic.

Deep Dive & Mechanics

The vulnerability resides in the web interface of Veritas Data Insight, specifically in functionality accessible to users with the "Application Administrator" role. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries. An attacker can inject malicious SQL statements through input fields (e.g., search boxes, configuration parameters, or API endpoints) that are not parameterized.

Attack Flow:

1. Authentication: The attacker must first obtain valid Application Administrator credentials (e.g., via phishing, credential stuffing, or insider access).
2. Injection Point: The attacker identifies an input field that is vulnerable to SQL injection. Common targets include search filters, report generation parameters, or user management forms.
3. Payload Delivery: The attacker crafts a malicious SQL payload (e.g., ' OR '1'='1 or a UNION-based injection) and submits it via the web interface.
4. Exploitation: The backend database executes the injected SQL, allowing the attacker to:
   • Extract sensitive data (e.g., user credentials, configuration secrets, backup metadata).
   • Modify or delete database records.
   • Execute stored procedures or commands (if database permissions allow).
5. Persistence/Privilege Escalation: The attacker may use the SQL injection to create new administrative accounts or modify existing ones, maintaining access even after the initial session ends.

Root Cause: The application uses dynamic SQL query construction without proper input validation or parameterized queries (prepared statements). This is a classic CWE-89 vulnerability.

Vulnerable vs. Patched Code

Since the exact source code is proprietary, the following is a representative example of the vulnerable pattern and the fix.

Vulnerable Code (Conceptual - Java/JDBC):

String query = "SELECT * FROM users WHERE username = '" + request.getParameter("username") + "'";
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery(query);

Patched Code (Conceptual - Java/JDBC with PreparedStatement):

String query = "SELECT * FROM users WHERE username = ?";
PreparedStatement pstmt = connection.prepareStatement(query);
pstmt.setString(1, request.getParameter("username"));
ResultSet rs = pstmt.executeQuery();

The patched version (7.1.1) likely implements parameterized queries or stored procedures for all database interactions, effectively neutralizing SQL injection attempts.

Exploitation & Lab Setup

Red Team (Offensive)

Prerequisites:

• A lab environment with Veritas Data Insight < 7.1.1 installed.
• Valid Application Administrator credentials (e.g., admin:password).
• A web proxy (e.g., Burp Suite) to intercept and modify requests.

Steps:

1. Identify Injection Point: Log in as an Application Administrator. Navigate to a feature that accepts user input (e.g., "Search Users" or "Generate Report"). Intercept the request with Burp Suite.
2. Test for SQLi: Submit a single quote (') in the input field. If an error message reveals database syntax (e.g., You have an error in your SQL syntax), the parameter is vulnerable.
3. Confirm with Boolean-Based Blind: Send ' AND '1'='1 (should return normal results) and ' AND '1'='2 (should return no results or an error).
4. Extract Data (UNION-based): Determine the number of columns using ' ORDER BY 1-- (increment until error). Then use a UNION SELECT to extract data:

   ' UNION SELECT null, username, password, null FROM users--
   

5. Automate with sqlmap:

   sqlmap -u "https://target/datainsight/search?q=test" --cookie="session=..." --data="q=test" --level=5 --risk=3 --batch
   

Note: No public exploit code is available. The above steps are generic SQL injection techniques.

Blue Team (Defensive)

Detection & Response:

1. Monitor Database Logs: Enable logging of all SQL queries. Look for anomalous patterns such as:
   • Queries containing OR, UNION, SELECT, INSERT, DELETE, DROP, EXEC.
   • Queries with excessive single quotes or comment characters (--, #).
   • Queries from the web application user that deviate from expected patterns.
2. Web Application Firewall (WAF): Deploy a WAF (e.g., ModSecurity) with rules to block common SQL injection patterns.
3. Input Validation: Ensure all user inputs are validated against a whitelist of allowed characters. Reject inputs containing SQL metacharacters.
4. Least Privilege: Ensure the database user used by the application has minimal permissions (e.g., only SELECT on necessary tables, no DDL or DML privileges).
5. Patch Immediately: Upgrade to Veritas Data Insight 7.1.1 or later.

Indicators of Compromise (IOCs)

• Network IOCs:
  • HTTP requests containing SQL keywords in GET/POST parameters (e.g., UNION, SELECT, OR 1=1).
  • Unusual database error messages in HTTP responses (e.g., SQL syntax, ORA-, MySQL).
• Host IOCs:
  • Unexpected database queries in logs (e.g., /var/log/mysql/query.log or Windows Event Logs).
  • New user accounts created in the Data Insight application.
  • Modified configuration files (e.g., web.xml, application.properties).
• File IOCs:
  • Temporary files or scripts dropped on the server (e.g., /tmp/exploit.sh).
  • Unusual outbound network connections from the Data Insight server (e.g., to an attacker-controlled IP).

Remediation & Mitigation

Immediate Actions:

1. Upgrade: Apply the vendor patch by upgrading to Veritas Data Insight 7.1.1 or later. This is the only definitive fix.
2. Workaround (if patching is delayed):
   • Restrict network access to the Data Insight web interface to trusted IP addresses only.
   • Implement a Web Application Firewall (WAF) with SQL injection prevention rules.
   • Disable or restrict the "Application Administrator" role to only essential personnel.
   • Enable detailed audit logging for all administrative actions.

Long-Term Measures:

• Conduct a security code review of the application, focusing on input validation and parameterized queries.
• Implement a secure development lifecycle (SDLC) with mandatory security testing (SAST/DAST).
• Regularly update and patch all software components.
• Enforce multi-factor authentication (MFA) for all administrative accounts.
