CVE-2024-7801
📋 TL;DR
This SQL injection vulnerability in Microchip TimeProvider 4100's data plot modules allows attackers to execute arbitrary SQL commands on the database. It affects TimeProvider 4100 devices running versions 1.0 through 2.4.6. Organizations using these devices for network time synchronization are at risk.
💻 Affected Systems
- Microchip TimeProvider 4100 Grandmaster
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the TimeProvider device, allowing data theft, configuration modification, or disruption of time synchronization services across the network.
Likely Case
Extraction of sensitive configuration data, modification of time settings, or denial of service affecting time-dependent applications.
If Mitigated
Limited impact if network segmentation and access controls prevent unauthorized access to the vulnerable interface.
🎯 Exploit Status
SQL injection vulnerabilities are commonly exploited with readily available tools. The unauthenticated nature makes exploitation straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.4.7
Restart Required: Yes
Instructions:
1. Download firmware version 2.4.7 from Microchip support portal. 2. Backup current configuration. 3. Apply firmware update via web interface or CLI. 4. Reboot device. 5. Verify version shows 2.4.7.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to TimeProvider web interface and management ports to authorized IPs only.
Use firewall rules to allow only specific management networks to access TCP ports 80/443 on the TimeProvider.
Disable Data Plot Modules
allIf not required, disable the vulnerable data plot modules to remove attack surface.
Access web interface > Configuration > Data Plot > Disable modules
🧯 If You Can't Patch
- Implement strict network segmentation to isolate TimeProvider devices from untrusted networks.
- Deploy a web application firewall (WAF) with SQL injection protection rules in front of the TimeProvider interface.
🔍 How to Verify
Check if Vulnerable:
Check firmware version via web interface (System > About) or CLI command 'show version'. If version is between 1.0 and 2.4.6 inclusive, device is vulnerable.Check Version:
show versionVerify Fix Applied:
Confirm firmware version shows 2.4.7 or higher. Test data plot functionality to ensure modules work without SQL errors.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple failed login attempts followed by SQL-like queries
- Unexpected configuration changes in system logs
Network Indicators:
- SQL keywords (SELECT, UNION, INSERT, etc.) in HTTP requests to TimeProvider
- Unusual traffic patterns to data plot endpoints
SIEM Query:
source="timeprovider_logs" AND ("sql" OR "syntax" OR "union" OR "select")
