CVE-2018-2756 in Communications Order
Summary
by MITRE
Vulnerability in the Oracle Communications Order and Service Management component of Oracle Communications Applications (subcomponent: WebUI). Supported versions that are affected are 7.2.4.3.0, 7.3.0.1.x, 7.3.1.0.7 and 7.3.5.0.x. Easily exploitable vulnerability allows low privileged 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. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Communications Order and Service Management accessible data as well as unauthorized update, insert or delete access to some of Oracle Communications Order and Service Management accessible data. CVSS 3.0 Base Score 6.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N).

The vulnerability identified as CVE-2018-2756 resides within the Oracle Communications Order and Service Management component, specifically within the WebUI subcomponent of Oracle Communications Applications. This security flaw affects multiple version streams including 7.2.4.3.0, 7.3.0.1.x, 7.3.1.0.7, and 7.3.5.0.x, representing a significant attack surface across the product's lifecycle. The vulnerability classification as easily exploitable indicates that threat actors can leverage this weakness with minimal technical sophistication, making it particularly dangerous in production environments where such systems handle critical business operations.
The technical nature of this vulnerability stems from insufficient authentication and authorization controls within the web user interface component, allowing a low privileged attacker with network access via HTTP to compromise the system. This weakness specifically enables unauthorized access to critical data and complete access to all accessible data within the Oracle Communications Order and Service Management environment. The vulnerability's CVSS 3.0 base score of 6.3 reflects the moderate severity, with confidentiality impact rated as high and integrity impact as low, indicating that while the primary concern is data exposure rather than modification, the potential for unauthorized data access remains substantial.
The operational impact of this vulnerability extends beyond simple data theft, as successful exploitation can lead to unauthorized update, insert, or delete operations against the system's accessible data. This creates a comprehensive threat scenario where attackers can not only view sensitive information but also manipulate business-critical data, potentially disrupting order processing, service management workflows, and customer relationship management processes. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted phishing attacks may be necessary to initiate the exploitation process, though this does not diminish the overall risk level.
The vulnerability aligns with CWE-287, which addresses improper authentication issues, and represents a classic case of weak session management or authentication bypass in web applications. From an ATT&CK framework perspective, this vulnerability maps to T1190 (Exploit Public-Facing Application) and T1078 (Valid Accounts), as it allows attackers to leverage network access to compromise systems without requiring elevated privileges initially. Organizations should implement immediate mitigations including applying Oracle's security patches, implementing network segmentation to limit access to the affected components, and strengthening authentication mechanisms. Additionally, monitoring for suspicious HTTP traffic patterns and implementing web application firewalls can help detect and prevent exploitation attempts.
The attack vector requires network access via HTTP, meaning that organizations should ensure proper network access controls are in place to restrict access to the affected WebUI components. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N) indicates that while the attack requires low complexity and low privilege, it does require user interaction, suggesting that user awareness training becomes critical to prevent exploitation through social engineering attacks. The high confidentiality impact combined with the potential for complete data access makes this vulnerability particularly concerning for organizations handling sensitive customer information, service orders, and business-critical communications data that the affected system manages.
