CVE-2017-3573 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). 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. Easily "exploitable" vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hospitality OPERA 5 Property Services. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hospitality OPERA 5 Property Services, 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 OPERA 5 Property Services accessible data as well as unauthorized read access to a subset of Oracle Hospitality OPERA 5 Property Services accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability described in CVE-2017-3573 represents a critical security flaw within the Oracle Hospitality OPERA 5 Property Services component, specifically within the OPERA Printing subcomponent. This issue affects a range of versions including 5.4.0.x through 5.4.3.x and 5.5.0.x through 5.5.1.x, indicating a widespread impact across multiple release branches of the hospitality management software. The vulnerability's classification as easily exploitable means that attackers can leverage it without requiring specialized tools or extensive technical expertise, making it particularly dangerous in production environments where such systems handle sensitive guest information and financial transactions.
The technical nature of this vulnerability stems from insufficient authentication mechanisms within the HTTP-based interface of the OPERA Printing component. Attackers can compromise the system through unauthenticated network access, bypassing normal security controls that would typically require valid credentials for system access. The CVSS 3.0 score of 6.1 reflects the moderate severity of the issue, with particular emphasis on confidentiality and integrity impacts. The attack vector AV:N indicates network-based exploitation, while AC:L suggests low attack complexity, making this vulnerability accessible to a broad range of threat actors. The PR:N designation confirms that no prior privileges are required for exploitation, and UI:R indicates that successful attacks require human interaction from a legitimate user, though this interaction is not necessarily initiated by the attacker.
The operational impact of this vulnerability extends beyond the immediate compromise of the OPERA 5 Property Services component, potentially affecting additional Oracle Hospitality products within the ecosystem. This cascading effect demonstrates how vulnerabilities in one component can create ripple effects throughout interconnected systems. Successful exploitation enables unauthorized modification of data through update, insert, and delete operations, while also providing unauthorized read access to sensitive information. The confidentiality impact is rated as low (C:L) but the integrity impact is also low (I:L), suggesting that while the scope of data exposure may be limited, the potential for data manipulation remains significant. This vulnerability particularly threatens hospitality environments where guest records, reservation data, and financial information are stored and managed, creating opportunities for data theft, manipulation, or disruption of business operations.
The implications of this vulnerability align with common attack patterns found in the ATT&CK framework, particularly in the credential access and persistence phases where attackers seek to establish unauthorized access to critical systems. From a CWE perspective, this vulnerability likely maps to CWE-287 which deals with improper handling of authentication. Organizations should implement immediate mitigations including network segmentation to isolate critical hospitality systems, deployment of web application firewalls to monitor and filter HTTP traffic, and implementation of additional authentication layers for the printing services. Regular security assessments and vulnerability scanning should be conducted to identify similar issues in other Oracle Hospitality components, while patch management processes must be established to ensure timely deployment of vendor security updates. The vulnerability underscores the importance of securing all components within enterprise systems, as even specialized modules like printing services can become entry points for broader system compromise, emphasizing the need for comprehensive security postures that address both traditional and specialized system components.
