dgraph-io · dgraph

Dgraph is vulnerable to an improper neutralization of special elements in data query logic, potentially allowing unauthenticated attackers to manipulate database queries.

Executive summary

An unauthenticated vulnerability in the Dgraph distributed GraphQL database allows for improper data query manipulation, presenting a significant risk to data confidentiality and integrity.

Vulnerability

This flaw (CWE-943) involves improper neutralization of special elements in data query logic. It allows an unauthenticated, remote attacker to influence the execution of database queries, which may lead to unauthorized data access or modification.

Business impact

The vulnerability carries a CVSS score of 8.6, reflecting the high risk to data held within the Dgraph database. Unauthorized access to query logic can lead to severe data breaches, unauthorized disclosure of sensitive information, or the modification of critical database records, impacting both business operations and regulatory compliance.

Remediation

Immediate Action: Update the Dgraph installation to version 25.3.8 or later to resolve the query logic vulnerability.

Proactive Monitoring: Review database query logs for patterns of unusual or malformed GraphQL requests that attempt to access restricted fields or unauthorized objects.

Compensating Controls: Implement a Web Application Firewall (WAF) to filter and sanitize incoming GraphQL queries, specifically blocking requests that exhibit suspicious structural anomalies.

Exploitation status

Public Exploit Available: Unknown

Analyst recommendation

Due to the critical nature of database security and the potential for unauthenticated access, upgrading to version 25.3.8 is mandatory. Organizations should prioritize this update to prevent potential data exfiltration and ensure the ongoing integrity of their GraphQL-based infrastructure.
