CVE-2017-10370 in Hospitality Guest Access
Summary
by MITRE
Vulnerability in the Oracle Hospitality Guest Access component of Oracle Hospitality Applications (subcomponent: Base). Supported versions that are affected are 4.2.0 and 4.2.1. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle Hospitality Guest Access. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hospitality Guest Access, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hospitality Guest Access accessible data as well as unauthorized update, insert or delete access to some of Oracle Hospitality Guest Access accessible data. CVSS 3.0 Base Score 6.9 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2017-10370 resides within the Oracle Hospitality Guest Access component of Oracle Hospitality Applications, specifically within the Base subcomponent. This flaw affects versions 4.2.0 and 4.2.1 of the software, representing a significant security weakness in hospitality management systems that serve thousands of hotels and resorts worldwide. The vulnerability operates within a critical subsystem that manages guest access and authentication, making it a prime target for malicious actors seeking unauthorized access to sensitive hospitality data. The affected system architecture processes guest information, reservation details, and access credentials through this vulnerable component, creating a potential pathway for data breaches and unauthorized system manipulation.
The technical nature of this vulnerability manifests as an easily exploitable flaw that requires an attacker with high privileges and network access via HTTP protocols to successfully compromise the system. According to CVSS 3.0 scoring, the vulnerability carries a base score of 6.9, indicating a moderate to high severity threat that specifically impacts confidentiality and integrity aspects of the system. The attack vector requires network access with low complexity and high privilege requirements, suggesting that attackers must already possess elevated credentials or have gained access to a privileged account within the organization. The vulnerability's classification under CWE (Common Weakness Enumeration) would likely fall within categories related to insufficient authorization or improper access control mechanisms, though the specific CWE number requires detailed analysis of the underlying flaw. The system's design appears to lack proper validation of access requests or authentication tokens, allowing malicious actors to bypass security controls when operating from a network position.
Operational impact of this vulnerability extends beyond the immediate compromise of Oracle Hospitality Guest Access, as successful attacks can significantly affect additional products within the hospitality ecosystem. The attack requires human interaction from individuals other than the attacker, indicating that social engineering or insider threats may play a role in exploitation, though this requirement does not eliminate the automated nature of the attack vector. The potential consequences include unauthorized access to critical guest data, which may contain personal identification information, financial details, and sensitive reservation information that hotels collect during guest interactions. The vulnerability enables attackers to achieve complete access to all accessible data within the Guest Access component, while also providing unauthorized update, insert, or delete capabilities for some data within the system. This broad access level means that attackers could not only read sensitive information but also modify or destroy guest records, potentially compromising guest privacy and operational integrity. The confidentiality impact is rated as high, indicating that the vulnerability could expose sensitive guest data to unauthorized parties, while the integrity impact is rated as low to moderate, suggesting that while modifications are possible, they may not immediately cause system-wide failures.
Mitigation strategies for CVE-2017-10370 should focus on immediate patch deployment for affected versions 4.2.0 and 4.2.1, as Oracle would have released security updates to address the specific authorization bypass vulnerability. Organizations should implement network segmentation to limit access to the Guest Access component, ensuring that only authorized personnel can reach the vulnerable subsystem. Additional controls should include enhanced monitoring of HTTP traffic for suspicious access patterns, implementation of multi-factor authentication for privileged accounts, and regular security audits of hospitality applications to identify similar vulnerabilities. The ATT&CK framework would categorize this vulnerability under privilege escalation techniques, specifically targeting the 'Valid Accounts' and 'Network Service Scanning' tactics that attackers might employ to exploit the system. Security teams should also consider implementing data loss prevention measures to monitor for unauthorized data access patterns and establish incident response procedures specifically designed to handle guest data breaches in hospitality environments. Organizations should conduct thorough vulnerability assessments of their entire hospitality application suite to identify any similar authorization flaws that may exist in other components or versions of the Oracle Hospitality platform.
