CVE-2024-8503
📋 TL;DR
An unauthenticated attacker can exploit a time-based SQL injection vulnerability in VICIdial to enumerate database records, including plaintext credentials stored by default. This affects all VICIdial installations with vulnerable versions exposed to network access.
💻 Affected Systems
- VICIdial
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).
🔒 Custom verification scripts are available for registered users. Sign up free to download automated test scripts.
- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to credential theft, data exfiltration, and potential lateral movement within the network.
Likely Case
Credential harvesting and sensitive data extraction from the VICIdial database.
If Mitigated
Limited information disclosure if database contains minimal sensitive data and proper network segmentation exists.
🎯 Exploit Status
Time-based SQL injection allows blind enumeration without direct output, but tools automate this process.
🛠️ Fix & Mitigation

🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict VICIdial access to trusted IP addresses only
iptables -A INPUT -p tcp --dport [VICIdial_port] -s [trusted_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [VICIdial_port] -j DROP
Database Credential Encryption
allEncrypt stored credentials to limit impact of database access
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to isolate VICIdial from untrusted networks
- Enable comprehensive logging and monitoring for SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test for time-based SQL injection using tools like sqlmap against VICIdial endpointsCheck Version:
Check VICIdial version in web interface or configuration filesVerify Fix Applied:
Re-run SQL injection tests to confirm they no longer succeed📡 Detection & Monitoring
Log Indicators:
- Unusual database query patterns
- Multiple requests with SQL syntax in parameters
- Requests causing abnormal response delays
Network Indicators:
- SQL keywords in HTTP requests to VICIdial
- Repeated requests with incremental delays
SIEM Query:
