CVE-2018-2881 in MICROS Retail-J
Summary
by MITRE
Vulnerability in the MICROS Retail-J component of Oracle Retail Applications (subcomponent: Database). Supported versions that are affected are 11.0.x, 12.0.x, 12.1.x, 12.1.1.x, 12.1.2.x and 13.1.x. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise MICROS Retail-J. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MICROS Retail-J accessible data as well as unauthorized read access to a subset of MICROS Retail-J accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of MICROS Retail-J. CVSS 3.0 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

The CVE-2018-2881 vulnerability resides within the MICROS Retail-J component of Oracle Retail Applications, specifically within the Database subcomponent, representing a significant security weakness that affects multiple version streams including 11.0.x, 12.0.x, 12.1.x, 12.1.1.x, 12.1.2.x, and 13.1.x. This vulnerability manifests as an easily exploitable security flaw that can be leveraged by low-privileged attackers who possess network access through HTTP protocols. The flaw operates within the retail application infrastructure, targeting the database layer that manages critical retail operations data and transactions.
The technical exploitation of this vulnerability stems from inadequate access controls and authentication mechanisms within the MICROS Retail-J framework, allowing unauthorized actors to perform data manipulation operations including unauthorized update, insert, and delete actions against specific database records. Additionally, attackers can achieve unauthorized read access to sensitive data subsets within the application's database, potentially exposing confidential retail information such as customer data, transaction records, and inventory details. The vulnerability also enables partial denial of service conditions that can disrupt normal retail operations and compromise system availability.
From a security impact perspective, this vulnerability aligns with CWE-284 (Improper Access Control) and represents a critical weakness in the application's security architecture that can be exploited using the CVSS 3.0 scoring system. The base score of 6.3 indicates a moderate to high severity threat level that affects confidentiality, integrity, and availability simultaneously. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) demonstrates that the attack requires network access with low complexity but requires a low privilege level, and affects the entire system without user interaction. The vulnerability's impact extends beyond simple data theft to include operational disruption through partial denial of service, potentially affecting point-of-sale systems and inventory management functions critical to retail operations.
Organizations implementing affected versions of Oracle Retail Applications should prioritize immediate mitigation strategies including applying the relevant Oracle security patches, implementing network segmentation to limit access to the vulnerable components, and conducting thorough security assessments of their retail infrastructure. The vulnerability's classification under ATT&CK matrix as a privilege escalation and data manipulation technique requires organizations to strengthen their access control policies and implement comprehensive monitoring of database activities. Security teams should also consider deploying intrusion detection systems that can identify suspicious HTTP traffic patterns and unauthorized database access attempts that may indicate exploitation of this vulnerability. The affected retail environments must undergo rigorous vulnerability scanning and penetration testing to identify potential attack vectors and ensure that the implemented mitigations effectively protect against both current and potential future exploitation attempts.
