Exploitation Conditions

Exploitation requires a valid low-privileged account on the Oracle Utilities NMS system with network access to the Mobile component over HTTP. The CVSS PR:L metric confirms authentication is required - unauthenticated exploitation is not supported by the available data. The 'easily exploitable' designation means no elevated complexity, race conditions, or special configuration beyond a standard installation is required. Limiting factors: the attacker must possess or obtain valid credentials (even low-privilege), the target must be running one of the five affected version ranges, and the Mobile component's HTTP interface must be reachable. Organizations that have network-segmented NMS HTTP interfaces to internal-only networks significantly reduce exposure; those with internet-exposed NMS Mobile endpoints face the highest risk.

Impact

The CVSS 3.1 base score of 4.3 (Medium) reflects a constrained impact: confidentiality only, low severity, and a required low-privileged account (PR:L). The 'easily exploitable' designation in Oracle's advisory language is Oracle's standard encoding for AC:L/PR:L/UI:N, meaning no special conditions or race windows are needed once the attacker holds a valid low-privileged account. No EPSS score was provided in the intelligence data, which limits probabilistic exploitation estimation. There is no CISA KEV listing and no known public POC, so real-world exploitation risk is currently speculative. The 'Authentication Bypass' tag creates a tension with PR:L: it may indicate that the low-privileged user can bypass object-level authorization to read data belonging to other users or higher-privilege roles, rather than gaining access without any credentials. This is a meaningful but contained risk - the scope does not change (S:U), and there is no integrity or availability impact. Priority for utilities organizations should be moderate: patch during the next maintenance window rather than emergency response, unless the NMS Mobile component is internet-facing.

Exploit ScenarioDerived

An attacker who holds a low-privileged account on an Oracle Utilities NMS instance - for example, a read-only field technician account - sends a crafted HTTP request to the Mobile component that bypasses authorization checks, returning confidential NMS data (such as network topology, asset details, or operational records) belonging to other users or higher-privileged roles. No public exploit code exists at time of analysis, but the 'easily exploitable' classification and AC:L/UI:N vector mean that a working exploit requires minimal sophistication once an account is obtained.

AnalysisAIv1 – Jul 22, 2026

Unauthorized data read in Oracle Utilities Network Management System's Mobile component allows low-privileged, network-adjacent attackers to access a subset of confidential NMS data via HTTP. Affected are five distinct version branches spanning 2.5.0.1.x through 25.12.0.0.x, as detailed in Oracle's July 2026 Critical Patch Update. Oracle classifies this as 'easily exploitable,' and the 'Authentication Bypass' tag suggests authorization control weaknesses beyond the low-privilege requirement implied by PR:L; no public exploit or CISA KEV listing exists at time of analysis.

RemediationAI

Apply the patches released in Oracle's July 2026 Critical Patch Update (CPU), available at https://www.oracle.com/security-alerts/cpujul2026.html. Oracle's CPU advisories include specific patch identifiers and upgrade paths for each affected version branch; the exact patched version numbers are not independently confirmed outside the Oracle advisory, so consult the CPU directly for the correct target version per your installed branch. If immediate patching is not possible, restrict network access to the NMS Mobile component's HTTP interface to only trusted internal network segments using firewall or network ACL rules - this does not eliminate the vulnerability but removes remote exploitability for external threat actors. Additionally, audit low-privileged user accounts with access to the Mobile component and apply the principle of least privilege to limit the data any single account can read, reducing the blast radius of unauthorized access.

Technical ContextAI · show details

Oracle Utilities Network Management System is an enterprise-grade SCADA-adjacent platform used by electric, gas, and water utilities for real-time grid and network operations. The affected component is the Mobile subsystem (CPE: cpe:2.3:a:oracle_corporation:oracle_utilities_network_management_system:*:*:*:*:*:*:*:*), which exposes functionality over HTTP. The CWE is unspecified (reported as N/A), but the 'Authentication Bypass' tag alongside a PR:L CVSS vector points to a likely authorization bypass or broken access control weakness (CWE-285 or CWE-862 class), where a legitimately authenticated low-privileged user can read data beyond their authorized scope - rather than a complete pre-authentication bypass. The attack surface is the HTTP interface of the Mobile component, exploitable over the network without user interaction.
