CVE-2024-47223: Mitel MiCollab SQL Injection Vulnerability

CVE-2024-47223 Overview

A critical SQL injection vulnerability has been identified in the AWV (Audio, Web and Video Conferencing) component of Mitel MiCollab through version 9.8 SP1 FP2 (9.8.1.201). This vulnerability allows an unauthenticated attacker to conduct SQL injection attacks due to insufficient sanitization of user input. A successful exploit enables attackers to access non-sensitive user provisioning information and execute arbitrary SQL database commands, potentially compromising data integrity and availability.

Critical Impact

Unauthenticated attackers can execute arbitrary SQL commands against the MiCollab database, potentially leading to data manipulation, unauthorized access to provisioning information, and service disruption.

Affected Products

• Mitel MiCollab versions through 9.8 SP1 FP2 (9.8.1.201)
• Mitel MiCollab AWV (Audio, Web and Video Conferencing) component
• All Mitel MiCollab deployments utilizing the AWV conferencing functionality

Technical Details for CVE-2024-47223

Vulnerability Analysis

CVE-2024-47223 represents a classic SQL injection vulnerability (CWE-89) within the AWV component of Mitel MiCollab. The vulnerability stems from the application's failure to properly sanitize user-supplied input before incorporating it into SQL queries. This allows attackers to manipulate database queries by injecting malicious SQL statements through unvalidated input parameters.

The AWV component, which handles audio, web, and video conferencing functionality, accepts user input that is directly concatenated into SQL queries without proper parameterization or escaping. This architectural weakness enables attackers to bypass authentication mechanisms and directly interact with the underlying database.

The attack can be executed remotely over the network without requiring any prior authentication or user interaction, making it particularly dangerous for internet-facing MiCollab deployments. Successful exploitation grants attackers the ability to read non-sensitive user provisioning data and execute arbitrary database commands, which could be leveraged to modify or delete data, escalate privileges, or cause service disruption.

Root Cause

The root cause of CVE-2024-47223 is insufficient input sanitization within the AWV component's database query construction logic. The application directly incorporates user-supplied input into SQL statements without using prepared statements, parameterized queries, or adequate input validation. This violates secure coding principles and exposes the application to injection attacks.

The vulnerability specifically affects the user provisioning workflow within the conferencing component, where input parameters are trusted and passed directly to the database layer without sanitization.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker can exploit this vulnerability by sending specially crafted HTTP requests to the vulnerable AWV component endpoints. The malicious input is processed by the application and incorporated into SQL queries, allowing the attacker to:

1. Bypass query logic to extract provisioning information
2. Execute arbitrary SQL commands to modify database contents
3. Potentially cause denial of service by corrupting database integrity
4. Chain with other vulnerabilities to achieve deeper system compromise

The attack surface is particularly concerning for organizations exposing MiCollab services to the internet, as the vulnerability requires no prior access or credentials to exploit.

Detection Methods for CVE-2024-47223

Indicators of Compromise

• Unusual SQL error messages in AWV component logs indicating injection attempts
• Anomalous database queries containing SQL metacharacters such as single quotes, UNION statements, or comment sequences
• Unexpected database access patterns or queries originating from the AWV application
• Evidence of data exfiltration or modification within MiCollab provisioning tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting MiCollab endpoints
• Deploy database activity monitoring to identify suspicious query patterns, including UNION-based injections, time-based blind injection attempts, and unauthorized SELECT/UPDATE/DELETE operations
• Configure SIEM alerts for anomalous traffic patterns to the AWV component, particularly requests containing SQL injection signatures
• Enable detailed logging on the MiCollab application and database layers to capture attempted exploitation

Monitoring Recommendations

• Monitor network traffic to MiCollab AWV endpoints for requests containing SQL injection payloads
• Implement real-time alerting for database queries originating from the AWV component that deviate from expected patterns
• Review MiCollab application logs regularly for error messages indicating malformed SQL queries
• Track authentication and provisioning access patterns to identify unauthorized data retrieval

How to Mitigate CVE-2024-47223

Immediate Actions Required

• Apply the security patch referenced in Mitel Security Advisory MISA-2024-0028 immediately
• Restrict network access to MiCollab AWV component to trusted networks only using firewall rules
• Implement Web Application Firewall protection in front of MiCollab deployments to filter malicious requests
• Review database access logs for any signs of prior exploitation before patching

Patch Information

Mitel has released a security update addressing CVE-2024-47223. Organizations should consult the Mitel Security Advisory MISA-2024-0028 for specific patch versions and installation guidance. Upgrade to a patched version of MiCollab that addresses the input sanitization deficiency in the AWV component.

Workarounds

• If immediate patching is not possible, consider temporarily disabling the AWV component if conferencing functionality is not critical
• Implement network segmentation to isolate MiCollab servers from untrusted networks
• Deploy a reverse proxy or WAF with SQL injection detection rules in front of the MiCollab application
• Monitor database activity closely and implement database-level query restrictions where feasible

# Example: Restrict network access to MiCollab AWV component
# Add firewall rules to limit access to trusted IP ranges only
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP

# Enable enhanced logging for SQL injection detection
# Review your WAF configuration to include SQL injection rules
