CVE-2026-62638 in Reports Developer
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Reports Developer product of Oracle Fusion Middleware (component: Security and Authentication). The supported version that is affected is 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Reports Developer. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Reports Developer accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Reports Developer. CVSS 3.1 Base Score 9.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H).

The identified vulnerability resides within the Oracle Reports Developer component of Oracle Fusion Middleware, specifically affecting version 14.1.2.0.0 under the Security and Authentication module. This flaw represents a critical security deficiency that permits unauthenticated attackers to exploit the system over standard HTTP network connections. The absence of required authentication checks allows remote adversaries with basic network access to interact directly with vulnerable endpoints without presenting valid credentials, thereby bypassing fundamental identity verification mechanisms designed to protect sensitive enterprise data processing environments.
From a technical perspective, this vulnerability facilitates unauthorized manipulation and destruction of critical information stored within the Oracle Reports Developer ecosystem. An attacker leveraging this flaw can execute commands or send crafted requests that result in the creation, deletion, or modification of high-value data assets accessible by the application. This capability directly compromises the integrity of the system, allowing for persistent changes to configuration files, report definitions, or underlying database records without authorization. The severity is further amplified by the potential for complete denial of service conditions; successful exploitation can trigger a hang or cause frequently repeatable crashes within the Oracle Reports Developer process, effectively rendering the application unavailable to legitimate users and disrupting business operations that rely on reporting services.
The operational impact of this vulnerability is severe, characterized by high integrity loss and availability disruption as reflected in its CVSS 3.1 base score of 9.1. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H) indicates that the attack requires no user interaction, has low complexity, and impacts a single system scope while causing high integrity and availability damage but no direct confidentiality breach in this specific instance. In practical terms, an attacker could deface reporting outputs, inject malicious logic into generated reports, or exhaust server resources through repeated crash-inducing requests, leading to significant downtime and potential data corruption that may require extensive recovery efforts from backups.
This vulnerability aligns with CWE-287 Improper Authentication, as the core failure lies in the system's inability to verify the identity of the requesting party before granting access to sensitive operations. Furthermore, it relates to CWE-613 insufficient Session Expiration and potentially CWE-400 Uncontrolled Resource Consumption if the denial-of-service aspect is exploited through resource exhaustion techniques. From a threat modeling perspective using MITRE ATT&CK, this behavior corresponds to Initial Access via Network Service Exposure and could facilitate Persistence or Impact categories depending on whether data modification leads to long-term backdoor installation or immediate service disruption.
Mitigation strategies must prioritize immediate patching of the Oracle Fusion Middleware environment to version 14.1.2.0.0 or later where this specific flaw has been addressed by vendor security updates. In addition to applying patches, organizations should implement network-level controls such as Web Application Firewalls (WAF) configured to detect and block anomalous HTTP requests targeting known vulnerable endpoints. Restricting access to Oracle Reports Developer interfaces through IP whitelisting for administrative functions can also reduce the attack surface. Regular vulnerability scanning and penetration testing focused on authentication bypasses are recommended to ensure that similar gaps in security controls do not exist elsewhere within the middleware infrastructure, ensuring compliance with industry best practices for application security management.
