The vulnerability identified as CVE-2017-10398 resides within the Oracle Hospitality Cruise Fleet Management component, specifically within the BaseMasterPage subcomponent of the Oracle Hospitality Applications suite. This particular vulnerability affects version 9.0.2.0 and represents a significant security weakness that can be exploited by attackers with legitimate access to the system infrastructure where the application executes. The CVSS 3.0 scoring system assigns this vulnerability a base score of 8.4, indicating a high severity threat that impacts both confidentiality and integrity aspects of the affected system. The attack vector is classified as local access (AV:L) requiring low complexity (AC:L) and low privileges (PR:L), suggesting that an attacker who already has login credentials and system access can exploit this weakness effectively.
The technical flaw manifests as an insufficient access control mechanism within the BaseMasterPage component, which fails to properly validate user permissions before allowing data manipulation operations. This weakness creates a pathway for privilege escalation attacks where a low-privileged user can gain unauthorized access to critical system resources. The vulnerability's impact extends beyond the immediate application scope as noted in the CVSS vector's scope change indicator (S:C), indicating that successful exploitation can affect additional products within the Oracle Hospitality ecosystem. This interconnected impact demonstrates how vulnerabilities in one component can create cascading security risks across related systems and applications.
From an operational standpoint, this vulnerability presents a severe risk to the integrity and confidentiality of cruise fleet management data. Attackers who successfully exploit this weakness can perform unauthorized creation, deletion, or modification operations on critical data within the Oracle Hospitality Cruise Fleet Management system. The potential for complete data access and modification capabilities means that sensitive operational information, passenger data, and fleet management records could be compromised. The CVSS score of 8.4 reflects the severity of potential data loss and system integrity violations that could occur, with the high confidentiality impact (C:H) indicating that attackers could access all sensitive data within the application's scope.
The security implications of CVE-2017-10398 align with CWE-284, which addresses improper access control vulnerabilities, and can be mapped to ATT&CK technique T1078 for valid accounts and T1484 for accounts with elevated privileges. Organizations utilizing Oracle Hospitality Cruise Fleet Management should implement immediate mitigations including applying the vendor-provided patches, implementing network segmentation to limit access to the affected system, and conducting thorough access control reviews. Additional protective measures should include monitoring for unauthorized access attempts, implementing privileged access management controls, and establishing robust audit trails to detect potential exploitation attempts. The vulnerability's classification as easily exploitable underscores the urgency for organizations to address this weakness promptly, as the low privilege requirements and local access vector make it particularly dangerous in environments where multiple users have legitimate system access.
