CVE-2026-83185 in Common Applications
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Common Applications product of Oracle E-Business Suite (component: CRM User Management Framework). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Common Applications. 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 Common Applications accessible data as well as unauthorized access to critical data or complete access to all Oracle Common Applications accessible data. CVSS 3.1 Base Score 7.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the CRM User Management Framework component of Oracle E-Business Suite, specifically affecting supported versions ranging from 12.2.3 through 12.2.15 in the Oracle Common Applications product line. This security flaw represents a significant risk to organizations relying on these enterprise resource planning and customer relationship management systems for their core business operations. The vulnerability is classified as easily exploitable, which lowers the barrier for potential attackers who possess network access via HTTP protocols. However, it requires low privileged user accounts rather than administrative privileges, indicating that an attacker does not need elevated system rights to initiate a successful exploitation attempt. This characteristic makes the threat particularly insidious because standard employee or contractor accounts often hold sufficient permissions to trigger the flaw without raising immediate alarms from security monitoring systems designed to detect high-privilege abuse.
The operational impact of this vulnerability is severe, primarily targeting data confidentiality and integrity while leaving availability largely unaffected according to the provided CVSS metrics. A successful exploitation allows an attacker with low privileges to compromise Oracle Common Applications by gaining unauthorized access to critical data or even complete access to all accessible data within the application scope. Furthermore, the flaw permits the unauthorized creation, deletion, or modification of this critical information. This capability effectively breaks the principle of least privilege and undermines trust in the integrity of business records stored within the E-Business Suite environment. Attackers could potentially alter financial records, modify customer contact details, delete essential transaction logs, or exfiltrate sensitive proprietary data without detection by traditional perimeter defenses that do not inspect internal application-layer traffic for such logic-based abuses.
From a technical perspective, this vulnerability aligns with common patterns found in web applications where input validation and access control mechanisms are insufficiently enforced within the user management framework. The requirement for human interaction suggests that the attack vector likely involves social engineering tactics or cross-site scripting scenarios where an attacker tricks another user into performing actions on their behalf while authenticated to the system. This aligns with CWE-79, which covers Cross-Site Scripting vulnerabilities, and potentially CWE-269 regarding Improper Privilege Management if the exploitation leads to privilege escalation beyond the initial low-level access. The attack technique is consistent with ATT&CK tactic T1059, specifically sub-techniques related to command or script interpretation via web browsers, as well as T1534 for Internal Spearphishing if human interaction involves deceiving a user into clicking malicious links within the application interface.
Mitigation strategies must prioritize immediate patching of all affected Oracle E-Business Suite instances to version 12.2.16 or later where this vulnerability has been addressed by the vendor. In environments where immediate patching is not feasible due to operational constraints, organizations should implement strict network segmentation to limit HTTP access to the CRM User Management Framework components only from trusted internal subnets. Additionally, deploying Web Application Firewalls with rulesets tuned for detecting common exploitation patterns associated with low-privilege privilege escalation and data manipulation can provide a layer of defense in depth. Security operations centers should also enhance monitoring around user management endpoints to detect anomalous activities such as bulk data exports or unexpected modifications by low-privileged accounts, ensuring that any potential exploitation attempts are identified and blocked before significant damage occurs.
