Attack-Flow Graph

Executive Summary

This vulnerability involves improper handling of LDAP authentication input, allowing an unauthenticated attacker to inject queries into the directory service under high-complexity conditions. It specifically affects Arista Networks CloudVision CUE.

Detection Guidance

Detecting this LDAP injection vulnerability requires monitoring LDAP queries for unusual patterns or unauthorized access attempts. Check LDAP server logs for unexpected query structures or repeated failed authentication attempts. Use network monitoring tools to inspect LDAP traffic for malformed queries or injection attempts.

Impact Analysis

An attacker could exploit this to manipulate LDAP queries, potentially accessing or altering sensitive directory information. This may lead to unauthorized data exposure or service disruption.

Compliance Impact

This vulnerability could compromise data confidentiality and integrity, violating GDPR and HIPAA requirements for secure authentication and access control. Non-compliance risks include legal penalties and reputational damage.

Mitigation Strategies

Apply vendor patches or updates for Arista Networks CloudVision CUE. Review and restrict LDAP query configurations to prevent unauthorized injection. Monitor network traffic for unusual LDAP queries or authentication attempts.
