CVE-2026-83477 in Work in Process
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Work in Process product of Oracle E-Business Suite (component: Workbenches). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Work in Process executes to compromise Oracle Work in Process. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Work in Process accessible data as well as unauthorized access to critical data or complete access to all Oracle Work in Process accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the Oracle Work in Process component of Oracle E-Business Suite, specifically affecting versions ranging from 12.2.3 through 12.2.15. This security flaw is categorized under the broader class of access control issues where an attacker can bypass authentication mechanisms to gain unauthorized privileges. The core technical deficiency lies in the insufficient validation or enforcement of access controls for specific endpoints within the Workbenches module, allowing individuals who have established a physical connection to the network segment hosting the Oracle Work in Process server to interact with sensitive application functions without providing valid credentials. This represents a significant deviation from standard security practices which mandate that all administrative and data-modifying actions require strict authentication regardless of network location.
From an operational perspective, this vulnerability poses a severe risk to organizations relying on Oracle E-Business Suite for manufacturing execution processes. Because the attack vector requires physical access to the communication segment attached to the hardware where the application executes, it is particularly relevant in environments with inadequate physical security controls or shared internal networks that are not properly segmented from untrusted zones. An attacker exploiting this flaw can achieve unauthorized creation, deletion, or modification of critical data within the Work in Process module. This capability directly impacts the integrity and confidentiality of manufacturing records, inventory levels, production schedules, and bill of materials configurations. The ability to alter such data without detection or authorization can lead to significant operational disruptions, financial loss due to incorrect production runs, and compromised supply chain visibility.
The impact assessment indicates a high severity level with a CVSS 3.1 Base Score of 8.1, primarily driven by the high impacts on confidentiality and integrity while availability remains unaffected in this specific vector description. The attack complexity is low, requiring no user interaction or prior authentication, which makes exploitation straightforward for any actor who can reach the target network segment. This aligns with Common Weakness Enumeration (CWE) identifiers such as CWE-287 Improper Authentication and CWE-915 Improper Authorization of Indirectly Controlled Security Component. The vulnerability also maps to MITRE ATT&CK techniques related to lateral movement or direct system access, specifically those involving exploitation of trusted relationships within a network perimeter where physical proximity provides an advantage over remote attackers who would face additional authentication barriers.
Mitigation strategies must address both the technical configuration and the environmental security posture. Oracle has likely released patches for this vulnerability in its Critical Patch Update releases; therefore, applying the latest available updates to all supported versions of Oracle E-Business Suite is the primary remediation step. Organizations should verify their current version against the affected range and prioritize patching systems that are exposed or accessible via internal networks with weak segmentation. In addition to software updates, implementing strict network access controls such as 802.1X port-based authentication can prevent unauthorized devices from connecting to the physical communication segment where the Oracle servers reside. Furthermore, deploying intrusion detection systems capable of identifying anomalous traffic patterns associated with unauthenticated exploitation attempts can provide an additional layer of defense. Regular audits of physical security measures for server rooms and network infrastructure are also essential to ensure that only authorized personnel have access to the hardware hosting critical enterprise applications.
