CVE-2026-101662 in Mobile Field Service
Summary
by MITRE • 10/21/2026
Vulnerability in the Oracle Mobile Field Service product of Oracle E-Business Suite (component: Admin UI). 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 Mobile Field Service. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Mobile Field Service accessible data as well as unauthorized read access to a subset of Oracle Mobile Field Service accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N).

The identified vulnerability resides within the Admin UI component of Oracle Mobile Field Service, a module integrated into the broader Oracle E-Business Suite ecosystem. This security flaw affects multiple supported releases, specifically versions ranging from 12.2.3 through 12.2.15. The nature of this defect represents a significant risk to organizations relying on these specific iterations for their mobile field service operations, as it undermines the integrity and confidentiality guarantees expected in enterprise-grade software deployments.
From a technical perspective, the vulnerability is characterized by an easily exploitable flaw that permits unauthorized actions without requiring complex attack vectors or user interaction. The primary prerequisite for exploitation is network access via HTTP to the affected system. Crucially, this does not require high-level privileges; instead, it can be leveraged by low-privileged attackers who have established a connection to the service. This lowers the barrier to entry significantly, allowing individuals with minimal initial access rights within an organization or external actors who have gained foothold in adjacent network segments to execute malicious operations against the core administrative functions of the application.
The operational impact of this vulnerability is severe due to its broad scope over data integrity and confidentiality. Successful exploitation enables attackers to perform unauthorized creation, deletion, or modification of critical data stored within Oracle Mobile Field Service. This capability directly compromises the integrity of business records, potentially leading to financial loss, regulatory non-compliance, or disruption of field operations if essential service logs or customer information are altered or destroyed. Furthermore, the vulnerability grants unauthorized read access to a subset of accessible data, which poses substantial confidentiality risks. Sensitive operational details, client information, or proprietary workflows could be exfiltrated by malicious actors exploiting this flaw.
In terms of industry-standard classification frameworks, this vulnerability aligns with CWE-269, Improper Privilege Management, as it allows low-privileged users to perform actions typically reserved for administrators. The ability to modify and delete critical data also maps closely to CWE-732, Incorrect Permission Assignment for Critical Resource, indicating a failure in enforcing strict access controls on sensitive system components. From an offensive security perspective, the exploitation technique corresponds to MITRE ATT&CK techniques involving unauthorized API access or improper authentication checks, specifically falling under tactics related to Privilege Escalation and Collection if data exfiltration is achieved through the read-access vector.
To mitigate this risk, organizations running affected versions of Oracle Mobile Field Service must prioritize immediate patching by applying the latest security updates provided by Oracle for their specific version line. Until patches are applied, network segmentation strategies should be reviewed to ensure that low-privileged users do not have direct HTTP access to the Admin UI endpoints from untrusted networks. Additionally, implementing strict input validation and enforcing role-based access controls at a proxy or web application firewall level can help block exploitation attempts by filtering out malformed requests associated with this vulnerability before they reach the backend logic of the E-Business Suite environment.
