CVE-2019-2829 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle iSupport component of Oracle E-Business Suite (subcomponent: Service Requests). Supported versions that are affected are 12.1.1 - 12.1.3 and 12.2.3 - 12.2.8. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle iSupport. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iSupport, 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 iSupport accessible data as well as unauthorized update, insert or delete access to some of Oracle iSupport accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2019-2829 resides within Oracle iSupport component of the Oracle E-Business Suite, specifically within the Service Requests subcomponent. This flaw affects a range of Oracle E-Business Suite versions including 12.1.1 through 12.1.3 and 12.2.3 through 12.2.8, representing a significant attack surface across multiple release lines. The vulnerability's classification as easily exploitable indicates that attackers can leverage it with minimal technical sophistication, making it particularly dangerous for organizations running affected systems. The security implications extend beyond the immediate iSupport component as the attack vector can impact additional Oracle products within the broader E-Business Suite ecosystem, creating cascading security risks.
The technical nature of this vulnerability manifests through an unauthenticated attack vector that operates over HTTP network protocols, allowing remote exploitation without requiring valid credentials or prior access to the system. The attack requires human interaction from users other than the attacker, suggesting that the exploitation may involve social engineering elements or targeted user engagement. This characteristic places additional risk on organizations where user behavior cannot be fully controlled or monitored, as users might inadvertently trigger the vulnerability through legitimate system interactions. The vulnerability's impact spans both confidentiality and integrity domains, with potential for unauthorized access to critical data and complete access to all Oracle iSupport accessible data, along with unauthorized modification capabilities to some accessible data.
The operational impact of CVE-2019-2829 represents a severe threat to enterprise security posture, with CVSS 3.0 Base Score of 8.2 indicating high severity. The vector analysis reveals network-based access with low attack complexity and no privilege requirements, making it particularly attractive to threat actors seeking broad system compromise. The potential for unauthorized access to critical data and complete data access creates risk for intellectual property theft, financial data compromise, and operational disruption. Additionally, the vulnerability's ability to enable unauthorized update, insert, or delete operations presents significant integrity risks that could lead to data corruption or manipulation. The security implications extend to the broader Oracle E-Business Suite environment, where successful exploitation could potentially compromise other integrated Oracle products and services.
Organizations should implement immediate mitigations including network segmentation to limit access to affected Oracle iSupport components, deployment of web application firewalls to monitor and filter HTTP traffic, and implementation of network access controls to restrict unauthorized access attempts. The vulnerability's classification aligns with CWE-287 (Improper Authentication) and CWE-312 (Sensitive Data Exposure) categories, reflecting fundamental security flaws in authentication mechanisms and data protection. From an ATT&CK framework perspective, this vulnerability maps to techniques involving Initial Access through Web Protocols and Credential Access through Network Sniffing, while also enabling Persistence and Privilege Escalation through data manipulation capabilities. Regular security assessments and vulnerability scanning should be conducted to identify any potential exploitation attempts, while patch management processes should be prioritized to address the underlying authentication and access control issues that enable this vulnerability.
