CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is a cypher injection vulnerability in Apache Syncope's persistence layer. It occurs when processing certain FIQL search conditions, allowing attackers to inject malicious Cypher queries into the system.

Detection Guidance

This vulnerability is specific to Apache Syncope's Neo4j persistence layer handling FIQL search conditions. Detection requires checking Syncope versions between 3.0.0-M0 to 3.0.16, 4.0.0-M0 to 4.0.7, and 4.1.0-M0 to 4.1.2. No direct commands are provided in the context. Review Syncope logs for unusual FIQL queries or Neo4j interaction patterns.

Impact Analysis

An attacker could exploit this to execute unauthorized database queries, potentially accessing, modifying, or deleting sensitive data. This could lead to data breaches or system compromise.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's data protection principles or HIPAA's security requirements. Non-compliance may result in legal penalties or reputational damage.

Mitigation Strategies
  • Upgrade Apache Syncope to version 4.0.8 or 4.1.3 or later to address the cypher injection vulnerability.
