CVE-2019-2492 in Email Center
Summary
by MITRE
Vulnerability in the Oracle Email Center component of Oracle E-Business Suite (subcomponent: Message Display). Supported versions that are affected are 12.1.1, 12.1.2, 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6, 12.2.7 and 12.2.8. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Email Center. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Email Center, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Email Center accessible data. CVSS 3.0 Base Score 4.7 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N).

The vulnerability identified as CVE-2019-2492 resides within Oracle Email Center, a component of the Oracle E-Business Suite that handles email messaging functionalities. This particular flaw exists in the Message Display subcomponent and affects multiple versions of the Oracle E-Business Suite including 12.1.1 through 12.2.8, representing a significant attack surface across the product lifecycle. The vulnerability's classification as easily exploitable indicates that attackers can leverage it with minimal technical sophistication, making it particularly dangerous for organizations that have not implemented proper network segmentation or access controls. The CVSS 3.0 score of 4.7 with a vector of AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N demonstrates that this vulnerability requires no authentication, has low attack complexity, and can be exploited through network access via HTTP protocols, while also requiring user interaction to complete the attack chain.
The technical nature of this vulnerability stems from insufficient input validation within the email message display functionality, which allows maliciously crafted HTTP requests to manipulate the application's behavior. Attackers can potentially inject malicious content or manipulate how email messages are rendered, leading to unauthorized data modification operations. The vulnerability's impact extends beyond the immediate Email Center component as indicated by the CVSS score's scope classification of S:C, suggesting that successful exploitation could affect additional Oracle products within the suite. This interconnected nature of Oracle E-Business Suite components means that compromise of one subsystem can potentially lead to broader system infiltration. The integrity impact score of I:L indicates that while the vulnerability does not allow for complete system compromise or data exfiltration, it enables unauthorized modification of data within the Email Center, which could be particularly damaging for email-based business processes and communication systems.
The operational impact of this vulnerability is significant for organizations using Oracle E-Business Suite, particularly those with unsecured network access to the Email Center component. The requirement for human interaction suggests that social engineering or phishing attacks could be employed to deliver malicious payloads, making this vulnerability particularly challenging to defend against from a security awareness perspective. Organizations may experience unauthorized modifications to email content, message routing configurations, or user-related data within the Email Center system, potentially disrupting business communications and creating security gaps in email-based workflows. The vulnerability's characteristics align with CWE-20, which describes improper input validation, and could be mapped to ATT&CK technique T1190 for the use of legitimate credentials and T1071 for application layer protocols. Effective mitigation requires immediate patching of affected systems, implementation of network access controls to restrict HTTP access to Email Center components, and enhanced monitoring for unusual data modification patterns within email systems. Additionally, organizations should consider implementing network segmentation strategies to isolate critical email infrastructure and establish robust incident response procedures to detect and respond to potential exploitation attempts.
