CVE-2026-83422 in Identity Manager
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Identity Manager product of Oracle Fusion Middleware (component: OIM Legacy UI). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Identity Manager. 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 Identity Manager accessible data as well as unauthorized access to critical data or complete access to all Oracle Identity Manager accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the Oracle Identity Manager product, specifically affecting its Legacy User Interface component in versions 12.2.1.4.0 and 14.1.2.1.0 of the Oracle Fusion Middleware suite. This security flaw represents a significant risk to organizations relying on these specific releases for identity and access management operations. The vulnerability is classified as easily exploitable, allowing an unauthenticated attacker who has network access via HTTP to compromise the integrity and confidentiality of the system. Unlike many modern web application vulnerabilities that require prior authentication or complex privilege escalation paths, this flaw permits direct exploitation by any remote actor with connectivity to the affected service interface, provided certain conditions are met regarding user interaction.
The operational mechanics of this exploit hinge on a critical design oversight in how the Legacy UI handles specific requests without enforcing adequate access controls or input validation for unauthenticated sessions. While the vulnerability allows an attacker to initiate actions that lead to unauthorized creation, deletion, or modification of data, it requires human interaction from a person other than the attacker to fully realize the impact. This characteristic aligns with Cross-Site Request Forgery patterns where social engineering is often employed to trick legitimate users into performing unintended actions within their authenticated session context, thereby leveraging their privileges against the system. The requirement for user interaction does not diminish the severity but rather shifts the attack vector towards exploiting trust relationships and human error in addition to technical flaws.
The impact of a successful exploitation is severe, encompassing both high confidentiality and integrity impacts as reflected by the CVSS 3.1 Base Score of 8.1. Attackers can achieve unauthorized access to critical data or gain complete access to all Oracle Identity Manager accessible data, leading to substantial breaches of sensitive identity information such as credentials, personal identifiable information, and organizational security policies. Furthermore, the ability to modify or delete critical data undermines the integrity of the entire identity management infrastructure. This could result in locked-out administrators, compromised service accounts, or the introduction of backdoors that persist beyond the initial exploitation window. The absence of availability impact suggests that while data is at risk, system uptime may remain unaffected during the immediate attack phase, though long-term operational disruption is likely due to the need for forensic remediation and potential downtime required to patch or restore from backups.
From a classification perspective, this vulnerability maps closely to CWE-352 Cross-Site Request Forgery if the mechanism involves tricking users into submitting forged requests, or potentially CWE-862 Missing Authorization if the flaw allows unauthenticated actors to perform actions reserved for authenticated roles through improper state management in the legacy interface. In terms of adversary tactics, this aligns with MITRE ATT&CK techniques related to Initial Access and Privilege Escalation, specifically those involving user interaction such as Spearphishing Attachment or Trusted Relationship Abuse if social engineering is used to trigger the vulnerability. The network-based nature via HTTP also highlights risks associated with CWE-319 Cleartext Transmission of Sensitive Information if sensitive data is exposed during the exploitation process over unencrypted channels.
Mitigation strategies must prioritize immediate remediation through vendor-supplied patches or updates that address the specific flaw in the Legacy UI component. Organizations running versions 12.2.1.4.0 and 14.1.2.1.0 should evaluate their exposure by assessing whether external-facing HTTP access to this interface is enabled, as restricting network access via firewall rules can significantly reduce the attack surface until patches are applied. Additionally, implementing strict Content Security Policy headers and ensuring that all administrative interfaces utilize modern authentication mechanisms rather than legacy protocols can help mitigate similar risks in other components. Regular security audits focusing on unauthenticated endpoints and rigorous testing of user interaction flows will further strengthen defenses against this class of vulnerabilities.
