CVE-2018-2827 in Hospitality Suite8
Summary
by MITRE
Vulnerability in the Oracle Hospitality Suite8 component of Oracle Hospitality Applications (subcomponent: Profile). The supported version that is affected is 8.x. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hospitality Suite8. 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 Hospitality Suite8 accessible data as well as unauthorized update, insert or delete access to some of Oracle Hospitality Suite8 accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Hospitality Suite8. CVSS 3.0 Base Score 7.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:H).

The vulnerability identified as CVE-2018-2827 resides within the Oracle Hospitality Suite8 component, specifically within the Profile subcomponent of Oracle Hospitality Applications. This security flaw affects versions 8.x of the suite and represents a significant concern for hospitality organizations that rely on Oracle's hospitality management systems. The vulnerability's classification as easily exploitable indicates that attackers can leverage relatively straightforward techniques to compromise the system, making it particularly dangerous for organizations that may not have robust security monitoring in place. The affected component operates within the hospitality ecosystem, managing guest profiles and related data that organizations consider critical for their operations.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Profile subcomponent. Attackers with low privileges and network access via HTTP can exploit this weakness to gain unauthorized access to sensitive data within the Oracle Hospitality Suite8 environment. The vulnerability requires human interaction from users other than the attacker, suggesting that social engineering or targeted phishing techniques might be necessary to initiate the attack vector successfully. This requirement for human interaction typically involves tricking legitimate users into performing actions that inadvertently trigger the vulnerability, making it more challenging to detect and prevent through automated security measures alone.
The operational impact of this vulnerability extends across all three fundamental pillars of information security: confidentiality, integrity, and availability. Successful exploitation can result in unauthorized access to critical guest data, potentially exposing sensitive personal information including names, addresses, contact details, and possibly financial information. The vulnerability also allows attackers to perform unauthorized updates, insertions, or deletions of data within the system, compromising data integrity and potentially leading to significant operational disruptions. Perhaps most critically, the vulnerability can enable attackers to cause complete denial of service conditions, either through system hangs or frequently repeatable crashes that can bring the entire Oracle Hospitality Suite8 system to a halt. This complete DOS capability represents a severe operational risk for hospitality businesses that depend on continuous system availability for their daily operations.
The CVSS 3.0 score of 7.6 reflects the severity of this vulnerability, with high impact scores across confidentiality and availability metrics. The vector (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:H) indicates that the attack requires network access with low complexity but requires low privilege levels, making it accessible to attackers with minimal resources. The requirement for user interaction suggests that this vulnerability may be exploited through targeted attacks against specific individuals within an organization rather than broad automated scanning campaigns. Organizations should consider implementing additional security controls beyond standard network perimeter defenses to protect against this type of attack vector, particularly given the human interaction component that makes it more difficult to detect through traditional security monitoring.
Organizations should prioritize immediate mitigation efforts including applying Oracle's security patches and updates, implementing network segmentation to limit access to the vulnerable components, and establishing enhanced monitoring for suspicious HTTP traffic patterns. The vulnerability aligns with CWE-20 (Improper Input Validation) and may relate to ATT&CK techniques involving credential access and privilege escalation. Regular security assessments and user awareness training are essential components of a comprehensive defense strategy against this type of vulnerability, particularly given the human interaction requirement that makes it susceptible to social engineering attacks.
