CVE-2017-3568 in Hospitality OPERA 5 Property Services
Summary
by MITRE
Vulnerability in the Oracle Hospitality OPERA 5 Property Services component of Oracle Hospitality Applications (subcomponent: OPERA Printing and Login). Supported versions that are affected are 5.4.0.x, 5.4.1.x, 5.4.2.x, 5.4.3.x, 5.5.0.x and 5.5.1.x. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle Hospitality OPERA 5 Property Services executes to compromise Oracle Hospitality OPERA 5 Property Services. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hospitality OPERA 5 Property Services accessible data as well as unauthorized access to critical data or complete access to all Oracle Hospitality OPERA 5 Property Services accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hospitality OPERA 5 Property Services. CVSS 3.0 Base Score 6.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L).

The vulnerability identified as CVE-2017-3568 affects the Oracle Hospitality OPERA 5 Property Services component within the broader Oracle Hospitality Applications suite, specifically targeting the OPERA Printing and Login subcomponents. This security flaw exists in multiple version streams including 5.4.0.x through 5.4.3.x and 5.5.0.x through 5.5.1.x, representing a significant attack surface within hospitality management systems. The vulnerability's classification as difficult to exploit indicates that while not trivial to leverage, it presents a genuine risk to organizations utilizing these specific versions of the property management software.
The technical nature of this vulnerability stems from insufficient authentication controls within the OPERA 5 Property Services execution environment. An attacker who has already gained logon access to the underlying infrastructure can exploit this weakness to compromise the property services component. This scenario represents a privilege escalation attack vector where the attacker leverages existing credentials to gain elevated access rights within the application. The requirement for human interaction from someone other than the attacker suggests that the exploitation may involve social engineering components or require specific user actions to complete the attack chain. The vulnerability's CVSS 3.0 base score of 6.5 reflects the substantial impact potential across confidentiality, integrity, and availability domains.
The operational impact of successful exploitation can be severe for hospitality organizations relying on the OPERA 5 system for critical business operations. Attackers could gain unauthorized access to modify, delete, or create data within the system, potentially affecting guest records, reservation data, financial transactions, and other sensitive operational information. The ability to achieve complete access to all accessible data represents a critical risk to data confidentiality and integrity, while the partial denial of service capability could disrupt hotel operations during peak periods. The vulnerability's impact extends beyond simple data compromise to potentially affect business continuity and customer service delivery within hospitality environments where OPERA 5 systems are deployed.
Organizations should implement immediate mitigations including applying available patches from Oracle to address the authentication weaknesses in the affected versions. Network segmentation and access controls should be strengthened to limit the attack surface where the property services execute, ensuring that only authorized personnel have access to these critical components. Monitoring for unusual access patterns and implementing robust audit trails can help detect exploitation attempts. The vulnerability aligns with CWE-287 which addresses improper authentication issues, and represents a potential ATT&CK technique under T1078 for valid accounts and T1486 for data encryption for ransom. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in related systems within the hospitality infrastructure.
