CVE-2023-1419

5.9 MEDIUM

📋 TL;DR

CVE-2023-1419 is a script injection vulnerability in Debezium database connectors where improper parameter sanitization allows attackers to inject malicious parameters. This could enable unauthorized data viewing from databases being monitored. Organizations using vulnerable Debezium connectors for database change data capture are affected.

💻 Affected Systems

Products:
  • Debezium database connectors
Versions: Specific versions not detailed in provided references; check Red Hat advisory for exact affected versions
Operating Systems: All platforms running Debezium
Default Config Vulnerable: ⚠️ Yes
Notes: Affects Debezium connectors when processing certain parameters; exact configuration requirements not specified in provided references.

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attacker gains unauthorized access to sensitive database records, potentially including credentials, PII, or proprietary business data.

🟠

Likely Case

Limited data exposure from databases being monitored by Debezium, potentially revealing table structures or partial data.

🟢

If Mitigated

No data exposure if proper input validation and network segmentation are implemented.

🌐 Internet-Facing: MEDIUM - Debezium connectors typically run internally but could be exposed through misconfigurations or API endpoints.
🏢 Internal Only: MEDIUM - Internal attackers or compromised systems could exploit this to access monitored database data.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires ability to send requests to Debezium connector endpoints with malicious parameters.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Red Hat advisory for specific patched versions

Vendor Advisory: https://access.redhat.com/security/cve/CVE-2023-1419

Restart Required: Yes

Instructions:

1. Check Red Hat advisory for affected versions. 2. Update Debezium connectors to patched version. 3. Restart Debezium services. 4. Verify functionality.

🔧 Temporary Workarounds

Input validation hardening

all

Implement additional input validation for Debezium connector parameters

Configuration depends on specific deployment; review and restrict parameter inputs in Debezium configuration

Network segmentation

linux

Restrict network access to Debezium connectors

firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="TRUSTED_NETWORK" port port="8083" protocol="tcp" accept'
ufw allow from TRUSTED_NETWORK to any port 8083

🧯 If You Can't Patch

  • Implement strict network access controls to limit who can communicate with Debezium connectors
  • Monitor Debezium logs for unusual parameter patterns or injection attempts

🔍 How to Verify

Check if Vulnerable:

Check Debezium version against Red Hat advisory; examine configuration for exposed endpoints

Check Version:

Check Debezium connector version in deployment configuration or via management interface

Verify Fix Applied:

Verify Debezium version is updated to patched version; test parameter inputs for proper sanitization

📡 Detection & Monitoring

Log Indicators:

  • Unusual parameter patterns in Debezium connector logs
  • Requests with suspicious parameter values

Network Indicators:

  • Unexpected requests to Debezium connector endpoints
  • Traffic patterns suggesting parameter manipulation

SIEM Query:

source="debezium" AND (param* OR injection OR script) NOT normal_parameter_pattern
