CVE-2024-9921: Teamplus Team+ Pro SQL Injection Flaw

CVE-2024-9921 Overview

CVE-2024-9921 is a critical SQL Injection vulnerability affecting Team+ from TEAMPLUS TECHNOLOGY. The application does not properly validate specific page parameters, allowing unauthenticated remote attackers to inject arbitrary SQL commands to read, modify, and delete database contents.

Critical Impact

Unauthenticated attackers can fully compromise the database by reading sensitive data, modifying records, or deleting database contents through malicious SQL injection payloads.

Affected Products

• Teamplus Team+ Pro (Private Cloud - Android)
• Team+ from TEAMPLUS TECHNOLOGY

Technical Details for CVE-2024-9921

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists due to improper input validation in the Team+ application. The vulnerable component fails to sanitize user-supplied input in specific page parameters before incorporating them into SQL queries. This allows attackers to manipulate query logic and execute arbitrary database operations.

The vulnerability is particularly severe because it requires no authentication to exploit. Remote attackers can directly interact with the backend database without any prior access or credentials, enabling complete database compromise including data exfiltration, modification, and deletion.

Root Cause

The root cause of CVE-2024-9921 is the lack of proper input validation and sanitization on specific page parameters within the Team+ application. User-controlled input is directly concatenated or interpolated into SQL queries without proper parameterization or escaping, creating a classic SQL injection attack surface. This represents a fundamental failure to follow secure coding practices for database query construction.

Attack Vector

The attack vector is network-based, requiring no user interaction or prior authentication. An attacker can craft malicious HTTP requests containing SQL injection payloads in the vulnerable page parameter. Upon processing, the application directly incorporates the malicious input into SQL queries, allowing the attacker to:

• Extract sensitive data from the database using UNION-based or blind SQL injection techniques
• Modify existing database records to escalate privileges or manipulate application state
• Delete database contents causing data loss and denial of service
• Potentially execute operating system commands if database permissions allow

The vulnerability can be exploited through standard web requests, making it accessible to any attacker with network access to the vulnerable application.

Detection Methods for CVE-2024-9921

Indicators of Compromise

• Unusual database query patterns containing SQL syntax characters such as single quotes, UNION statements, or comment sequences (--, /**/)
• Anomalous web requests with encoded SQL payloads targeting page parameters
• Database error messages appearing in application logs or responses indicating malformed queries
• Unexpected data modifications or deletions in application database tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in request parameters
• Enable detailed database query logging to identify suspicious query structures and unauthorized data access attempts
• Implement application-level input validation logging to capture rejected or suspicious input patterns
• Configure intrusion detection systems (IDS) to alert on network traffic containing SQL injection signatures

Monitoring Recommendations

• Monitor database audit logs for unusual SELECT, UPDATE, INSERT, or DELETE operations, especially those accessing sensitive tables
• Track authentication failures and anomalous session patterns that may indicate exploitation attempts
• Set up alerts for application errors related to database connectivity or query execution failures
• Review web server access logs for requests with unusual parameter values or encoding patterns

How to Mitigate CVE-2024-9921

Immediate Actions Required

• Apply vendor security patches immediately upon availability from TEAMPLUS TECHNOLOGY
• Implement network segmentation to restrict access to the Team+ application from untrusted networks
• Deploy WAF rules specifically targeting SQL injection attacks on the vulnerable endpoints
• Review database permissions and apply principle of least privilege to application database accounts
• Enable comprehensive logging for forensic analysis and ongoing monitoring

Patch Information

Organizations should consult the TW-CERT Security Advisory for official remediation guidance and patch availability from TEAMPLUS TECHNOLOGY. Contact the vendor directly for the latest security updates addressing CVE-2024-9921.

Workarounds

• Implement strict input validation on all user-supplied parameters at the application perimeter using a Web Application Firewall
• Restrict network access to the Team+ application to trusted IP ranges only until patching is complete
• Consider temporarily disabling the vulnerable functionality if business operations permit
• Deploy database activity monitoring to detect and alert on suspicious query patterns in real-time
• Ensure database accounts used by the application have minimal required privileges to limit exploitation impact

# Example WAF rule to block common SQL injection patterns (adjust for your WAF platform)
# This is a generic mitigation and should be customized for your environment
# Consult your WAF documentation for proper syntax

# Block requests containing common SQL injection keywords in parameters
