CVE-2018-2567 in Communications BRM
Summary
by MITRE
Vulnerability in the Oracle Communications Order and Service Management component of Oracle Communications Applications (subcomponent: Portal). Supported versions that are affected are 7.2.4.1.x, 7.2.4.2.x, 7.3.0.x.x and 7.3.0.1.x. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Communications Order and Service Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Communications Order and Service Management, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Communications Order and Service Management accessible data as well as unauthorized read access to a subset of Oracle Communications Order and Service Management accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2018-2567 resides within the Oracle Communications Order and Service Management component, specifically within the Portal subcomponent of Oracle Communications Applications. This security flaw affects multiple version streams including 7.2.4.1.x, 7.2.4.2.x, 7.3.0.x.x, and 7.3.0.1.x, representing a significant attack surface for potential adversaries targeting telecommunications and communications infrastructure. The vulnerability's classification as easily exploitable indicates that attackers can leverage standard network-based techniques without requiring privileged access or specialized tools, making it particularly dangerous for organizations relying on these communication platforms. The CVSS 3.0 score of 6.1 reflects moderate severity with specific impacts to confidentiality and integrity, though the vector analysis reveals the vulnerability requires network access via HTTP and human interaction, suggesting a more targeted attack approach.
The technical nature of this vulnerability stems from insufficient authentication mechanisms within the Portal component, allowing unauthenticated attackers to gain unauthorized access to sensitive data and operations within the Oracle Communications Order and Service Management system. This flaw operates at the application layer where HTTP protocols are processed, enabling attackers to perform unauthorized update, insert, and delete operations against database records accessible through the portal interface. The vulnerability's impact extends beyond the immediate component, as successful exploitation can affect additional products within the Oracle Communications ecosystem, demonstrating the interconnected nature of enterprise communication platforms. The requirement for human interaction suggests that attackers may need to persuade users to perform specific actions, potentially through social engineering techniques or by exploiting user trust in legitimate system interactions.
Operational impact of this vulnerability manifests in several critical areas including data integrity compromise, unauthorized data modification, and potential exposure of sensitive customer information. The ability to perform unauthorized updates, inserts, and deletes creates opportunities for data corruption, manipulation, or complete data loss within the communications management system. Organizations utilizing this platform may experience service disruption, regulatory compliance violations, and potential financial losses due to compromised customer data. The unauthorized read access capability particularly threatens privacy and confidentiality of communications data, as attackers could potentially access sensitive information related to customer orders, service configurations, and business operations. The CVSS vector's classification of "significant impact" to additional products indicates that this vulnerability could serve as a stepping stone for broader attacks within enterprise networks.
Mitigation strategies for CVE-2018-2567 should prioritize immediate patch deployment from Oracle, as this represents the most effective defense against exploitation. Organizations should implement network segmentation to limit access to the vulnerable portal component, particularly restricting HTTP access to authorized administrative networks only. Additional protective measures include implementing robust web application firewalls to monitor and filter HTTP traffic, enforcing strict access controls through authentication mechanisms, and conducting regular vulnerability assessments to identify similar weaknesses. Security teams should also establish monitoring procedures to detect unusual access patterns or unauthorized data modifications within the communications management system. The vulnerability's classification aligns with CWE-284 (Improper Access Control) and may map to ATT&CK techniques involving privilege escalation and credential access, emphasizing the need for comprehensive security controls beyond simple patching. Organizations should also consider implementing intrusion detection systems specifically configured to identify exploitation attempts targeting this vulnerability class.
