CVE-2026-62637 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 access to the physical communication segment attached to the hardware where the Oracle Reports Developer executes to compromise Oracle Reports Developer. While the vulnerability is in Oracle Reports Developer, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Reports Developer accessible data as well as unauthorized access to critical data or complete access to all Oracle Reports Developer accessible data. CVSS 3.1 Base Score 9.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N).

The identified vulnerability resides within the Security and Authentication component of Oracle Reports Developer, specifically affecting version 14.1.2.0.0 as part of the Oracle Fusion Middleware suite. This flaw represents a critical security deficiency that undermines the fundamental trust model of the application by allowing unauthenticated actors to bypass authentication mechanisms entirely. The nature of this vulnerability is particularly severe because it does not require user interaction or complex social engineering tactics, nor does it demand high levels of technical sophistication from the attacker. Instead, the primary prerequisite for exploitation is network-level proximity; an adversary must have access to the physical communication segment attached to the hardware where Oracle Reports Developer executes. This typically implies that the target system resides on a local area network or a shared broadcast domain where passive sniffing or active injection attacks are feasible without traversing perimeter defenses such as firewalls or intrusion detection systems designed for remote internet traffic.
From a technical perspective, the vulnerability likely stems from insufficient validation of incoming requests at the authentication layer, allowing an attacker to manipulate session tokens, exploit weak cryptographic implementations, or leverage logic flaws in how credentials are processed and verified. Because the attack vector is classified as Adjacent Network (AV:A) with Low Complexity (AC:L), it suggests that while the exploitation path is straightforward, it is constrained by physical network topology. However, once an attacker gains a foothold on this segment, they can execute malicious payloads or inject forged authentication headers to impersonate legitimate users or bypass access controls entirely. The absence of required privileges for the initial attack (PR:N) and user interface interaction (UI:N) further lowers the barrier to entry, making this vulnerability attractive to opportunistic attackers who may already have some level of network visibility within an organization's internal infrastructure.
The operational impact of successfully exploiting this flaw is substantial, characterized by high impacts on both confidentiality and integrity while availability remains largely unaffected according to the provided CVSS metrics. An attacker can achieve unauthorized creation, deletion, or modification of critical data stored within Oracle Reports Developer, as well as access all other data accessible through the application. This scope change indicates that compromising this single component can lead to a broader compromise of associated products and services integrated with Oracle Fusion Middleware. The ability to alter critical data poses severe risks to business continuity, regulatory compliance, and organizational reputation, particularly in environments where reporting tools are used for financial auditing, operational monitoring, or decision-making processes reliant on accurate historical records. Furthermore, complete access to all accessible data exposes sensitive intellectual property, customer information, and proprietary algorithms to potential exfiltration or manipulation.
In terms of industry standard classifications, this vulnerability aligns with CWE-287 (Improper Authentication) as the root cause, where the system fails to adequately verify identity before granting access. The attack pattern corresponds to ATT&CK technique T1078 (Valid Accounts), specifically involving local accounts or default credentials if applicable, and potentially T1556 (Modifying Authenticators) depending on how session states are managed. The high CVSS 3.1 Base Score of 9.3 reflects the severity due to the combination of low attack complexity, lack of required privileges, and significant impact on data integrity and confidentiality across a wide scope of affected systems. This scoring underscores that while network proximity is a limiting factor, the consequences within that boundary are catastrophic for any organization relying on Oracle Reports Developer for critical operations.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. The primary defense involves applying the latest security patches provided by Oracle to update the Oracle Reports Developer component to a version where this authentication flaw has been resolved. Organizations should also implement strict network segmentation policies to isolate systems running vulnerable middleware from general-purpose user networks, ensuring that only authorized administrative workstations or specific service accounts can communicate with these servers over trusted segments. Additionally, deploying host-based intrusion detection systems and monitoring for anomalous authentication attempts can help detect exploitation efforts in real-time. For environments where patching is not immediately feasible, implementing virtual private network tunnels or zero-trust access controls to restrict direct adjacent network access to the affected hardware serves as a critical compensating control until permanent fixes are deployed.
