CVE-2020-37033: Infor Storefront B2B SQLi Vulnerability

CVE-2020-37033 Overview

Infor Storefront B2B 1.0 contains a SQL injection vulnerability that allows attackers to manipulate database queries through the usr_name parameter in login requests. This vulnerability enables attackers to inject malicious SQL code into the usr_name parameter to potentially extract or modify database information, representing a significant security risk for organizations using this e-commerce platform.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability via the network to access sensitive database information, potentially leading to data breach, credential theft, or unauthorized modification of critical business data.

Technical Details for CVE-2020-37033

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists in the authentication mechanism of Infor Storefront B2B 1.0. The application fails to properly sanitize user-supplied input in the usr_name parameter during login requests, allowing attackers to inject arbitrary SQL statements that are executed directly against the backend database.

The vulnerability is accessible over the network without requiring authentication or user interaction, making it particularly dangerous for internet-facing deployments. An attacker can leverage this flaw to bypass authentication, extract sensitive data from the database (including customer information, credentials, and business data), or potentially modify database records.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries in the login functionality. The application directly concatenates user-supplied input from the usr_name parameter into SQL queries without proper sanitization or the use of prepared statements, allowing malicious SQL code to be interpreted as part of the database query.

Attack Vector

The attack is conducted over the network by sending specially crafted HTTP requests to the login endpoint. An attacker can inject SQL commands through the usr_name parameter field, which the application processes without adequate input validation. This allows the attacker to modify the query logic to bypass authentication, retrieve unauthorized data using UNION-based or blind SQL injection techniques, or manipulate database contents.

The vulnerability does not require any prior authentication, making it exploitable by unauthenticated remote attackers. Technical details and proof-of-concept information are available through the Exploit-DB #48674 entry.

Detection Methods for CVE-2020-37033

Indicators of Compromise

• Unusual SQL error messages in application logs containing syntax errors or database-specific error codes
• Login attempts with abnormal characters in the username field such as single quotes, double dashes, or SQL keywords like UNION, SELECT, OR
• Unexpected database query patterns or increased database load during authentication requests
• Evidence of data exfiltration or unauthorized database access in audit logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in login parameters
• Monitor authentication logs for repeated failed login attempts with suspicious payloads
• Deploy database activity monitoring to identify anomalous query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Enable verbose logging on the Infor Storefront B2B application and database server
• Monitor network traffic for suspicious HTTP POST requests to login endpoints containing SQL metacharacters
• Set up alerts for database errors that may indicate attempted SQL injection attacks
• Regularly review access logs for patterns consistent with automated vulnerability scanning tools

How to Mitigate CVE-2020-37033

Immediate Actions Required

• Restrict network access to the Infor Storefront B2B login endpoint to trusted IP ranges where possible
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the application
• Monitor and audit all database access for signs of exploitation
• Consider taking the application offline if it processes sensitive data until a fix can be applied

Patch Information

Organizations should contact Infor directly for information regarding security patches or updated versions that address this vulnerability. Review the VulnCheck Advisory for Infor for additional remediation guidance.

Workarounds

• Implement input validation at the application layer to reject login requests containing SQL metacharacters
• Deploy a WAF rule specifically filtering the usr_name parameter for SQL injection patterns
• Use network segmentation to limit access to the vulnerable application from untrusted networks
• Enable database query logging and implement alerting for suspicious query patterns

# Example WAF rule configuration (ModSecurity)
SecRule ARGS:usr_name "@detectSQLi" \
    "id:1001,phase:2,deny,status:403,msg:'SQL Injection Detected in usr_name parameter'"
