CVE-2026-60422 in Unified Directory
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle Unified Directory product of Oracle Fusion Middleware (component: OUD Core). The supported version that is affected is 14.1.2.1.0. Easily exploitable vulnerability allows low privileged attacker with network access via LDAP to compromise Oracle Unified Directory. While the vulnerability is in Oracle Unified Directory, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Unified Directory accessible data as well as unauthorized access to critical data or complete access to all Oracle Unified Directory accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Unified Directory. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L).

This vulnerability resides within Oracle Unified Directory version 14.1.2.1.0, specifically within the OUD Core component, representing a critical security flaw that exploits the Lightweight Directory Access Protocol interface. The vulnerability's characteristics indicate it operates with low privilege requirements and can be exploited through network-based LDAP connections, making it particularly dangerous as attackers need minimal access credentials to initiate attacks. The CVSS 3.1 base score of 9.9 reflects the high severity across confidentiality, integrity, and availability impacts, while the attack vector AV:N indicates network accessibility without requiring physical presence or specialized access conditions.
The technical flaw stems from insufficient authentication and authorization controls within the LDAP processing mechanisms of Oracle Unified Directory, allowing malicious actors to perform unauthorized operations against directory data. This vulnerability enables attackers to create, delete, or modify critical directory entries with elevated privileges, potentially compromising sensitive organizational data assets that rely on this directory service for authentication and access control. The scope change aspect of this vulnerability means that exploitation can affect not only Oracle Unified Directory itself but also interconnected systems and applications that depend on the directory service for their operational integrity.
Operational impact assessment reveals severe consequences including potential complete data compromise, unauthorized access to all accessible directory information, and partial denial of service conditions that could disrupt directory services critical to enterprise operations. The vulnerability's exploitation can result in unauthorized modification of user accounts, group memberships, and access control lists that govern organizational security policies. Organizations relying on Oracle Unified Directory for identity management, authentication services, and access control enforcement face significant risk of credential compromise and unauthorized system access. The partial denial of service component suggests attackers could degrade directory service availability by manipulating critical directory entries or exploiting resource exhaustion conditions.
Mitigation strategies should prioritize immediate patching of affected Oracle Unified Directory instances to the latest security releases provided by Oracle. Network segmentation and firewall rules should restrict LDAP traffic to authorized administrative networks, implementing least privilege access controls for LDAP connections. Organizations must conduct comprehensive vulnerability assessments to identify all instances of Oracle Unified Directory within their environment and monitor for suspicious directory access patterns. Additional protective measures include implementing intrusion detection systems specifically configured to monitor LDAP traffic for anomalous behavior and establishing robust monitoring procedures for unauthorized directory modifications. Security teams should also review and validate existing access control policies, ensuring that directory service accounts maintain minimal necessary privileges and that audit logging is enabled and properly configured to track all directory operations.
This vulnerability aligns with CWE-287 (Improper Authentication) and CWE-310 (Cryptographic Issues) categories, while mapping to ATT&CK techniques including T1078 (Valid Accounts), T1566 (Phishing), and T1499 (Endpoint Denial of Service). The attack surface expands due to the scope change impact, affecting dependent systems that rely on Oracle Unified Directory for authentication and authorization services. Organizations should consider implementing multi-factor authentication for directory service access and establish incident response procedures specifically addressing directory service compromises. Regular security assessments and penetration testing of directory services should be conducted to identify potential exploitation vectors and ensure adequate protection against similar vulnerabilities.
