CVE-2017-10221 in Hospitality RES 3700
Summary
by MITRE
Vulnerability in the Oracle Hospitality RES 3700 component of Oracle Hospitality Applications (subcomponent: OPS Operations). The supported version that is affected is 5.5. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Hospitality RES 3700 executes to compromise Oracle Hospitality RES 3700. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hospitality RES 3700, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Hospitality RES 3700 accessible data as well as unauthorized read access to a subset of Oracle Hospitality RES 3700 accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hospitality RES 3700. CVSS 3.0 Base Score 5.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:L).

The vulnerability identified as CVE-2017-10221 resides within the Oracle Hospitality RES 3700 component of Oracle Hospitality Applications, specifically within the OPS Operations subcomponent. This system serves as a critical backend infrastructure for hospitality operations management, handling reservation processing and operational data management for hotel and resort environments. The affected version 5.5 represents a widely deployed system architecture that processes sensitive guest information, reservation data, and operational metrics. The vulnerability's classification as difficult to exploit indicates that while it requires specific conditions to be leveraged successfully, the attack surface remains significant given the system's operational importance in hospitality environments.
The technical flaw manifests as a privilege escalation vulnerability that operates under specific conditions requiring an attacker to possess legitimate login credentials to the target infrastructure. This low-privileged attacker position creates a dangerous scenario where legitimate system access can be weaponized to compromise the entire RES 3700 application. The vulnerability's characteristics align with CWE-269, which addresses insufficient privileges in system components, and the attack vector requires local access with user-level privileges, making it particularly concerning for environments where administrative credentials might be compromised through social engineering or credential theft attacks.
The operational impact of this vulnerability extends beyond the immediate RES 3700 system, as indicated by the CVSS vector's scope classification of S:C, suggesting that successful exploitation can affect additional products within the broader Oracle Hospitality ecosystem. Attackers can achieve unauthorized modification of data through update, insert, or delete operations on sensitive reservation and guest information, while also gaining unauthorized read access to confidential operational data. The partial denial of service capability further compounds the risk by potentially disrupting reservation processing and operational workflows that depend on the system's availability. This multi-faceted impact aligns with ATT&CK technique T1078 for valid accounts and T1499 for endpoint disruption, demonstrating how this vulnerability can serve as a foundation for broader compromise activities.
Mitigation strategies should focus on implementing robust access controls and privilege management protocols within the hospitality environment. Network segmentation and micro-segmentation techniques can help limit the potential impact of credential compromise by isolating the RES 3700 system from other critical infrastructure components. Regular security assessments and privileged access monitoring should be implemented to detect anomalous access patterns that might indicate exploitation attempts. The CVSS score of 5.0 indicates a medium severity vulnerability that requires immediate attention, particularly given the potential for data integrity compromise and service disruption in hospitality environments where operational continuity is critical. Organizations should also consider implementing additional logging and monitoring capabilities specifically for the RES 3700 system to detect unauthorized access attempts and data manipulation activities. The vulnerability's requirement for human interaction through additional users beyond the attacker suggests that social engineering components should also be addressed through comprehensive security awareness training for personnel with access to these systems.
