Vulnerability Assessment

Exploitation Conditions

Exploitation requires the attacker to possess a low-privileged account with interactive logon access to the infrastructure/host where Oracle Utilities Network Management System executes (AV:L, PR:L) - it is NOT remotely reachable over the network and NOT unauthenticated. No user interaction is needed (UI:N) and attack complexity is low (AC:L), so once local authenticated access is held, exploitation is reliable against affected versions (2.4.0.1.0-2.4.0.1.33, 2.5.0.1.0-2.5.0.1.18, 2.5.0.2.0-2.5.0.2.11, 2.6.0.1.0-2.6.0.1.12, 2.6.0.2.0-2.6.0.2.9, 25.12.0.0.0-25.12.0.0.2). The primary limiting factor is the requirement for pre-existing authenticated local access; impact is confined to confidentiality (data disclosure), with no integrity or availability effect.

Impact

This is a moderate, not high-priority, issue. The CVSS 3.1 base score is 5.5 (Medium), driven entirely by a confidentiality impact (C:H/I:N/A:N) with a local attack vector (AV:L), low complexity (AC:L), low privileges required (PR:L), and no user interaction (UI:N). The vector confirms the attacker must already have authenticated logon access to the infrastructure where the product runs - this is not remotely exploitable and not an unauthenticated flaw, which significantly limits real-world reach. No EPSS score was provided in the input (exploitation probability unknown), the CVE is not listed in CISA KEV, and no public exploit code is referenced, so there is no public exploit identified at time of analysis. The SSVC framework cannot be fully applied as exploitation status is 'none observed', automatable is likely 'no' (requires prior authenticated local access), and technical impact is partial (data disclosure only). Signals are broadly consistent - a medium-severity, authenticated, local information-disclosure bug - with one conflict: the input Tag 'Authentication Bypass' contradicts the CVSS vector, which requires existing low privileges (PR:L) rather than bypassing authentication. The Oracle advisory label of 'unauthorized access to critical data' aligns with C:H but does not elevate this to critical-priority given the local, authenticated prerequisites.

Exploit ScenarioDerived

An attacker who already holds a low-privileged account with logon access to the server or infrastructure hosting Oracle Utilities Network Management System abuses the System Wide component to read data they should not be authorized to see. Because the attack vector is local (AV:L) with low complexity and no user interaction, a malicious insider or an attacker who has gained a foothold via another vector can reliably extract sensitive outage-management and grid data. No public proof-of-concept exploit is referenced in the available data.

AnalysisAIv1 – Oct 21, 2026

Local low-privileged users with logon access to hosts running Oracle Utilities Network Management System can read critical application data across affected 2.4.0.1.x, 2.5.0.1.x, 2.5.0.2.x, 2.6.0.1.x, 2.6.0.2.x, and 25.12.0.0.x releases. The issue is rated CVSS 5.5 with confidentiality-only impact; exploitation requires an existing local account (AV:L/PR:L) and low complexity, not remote or unauthenticated access. No public exploit code or CISA KEV entry was identified in the provided data, so this is a moderate-priority patching item rather than an emergency.

RemediationAI

Apply the Oracle Critical Patch Update October 2026 referenced at https://www.oracle.com/security-alerts/cpuoct2026.html; the provided data does not specify an exact fixed build, so confirm the corrected release for each affected train (2.4.0.1.0-2.4.0.1.33, 2.5.0.1.0-2.5.0.1.18, 2.5.0.2.0-2.5.0.2.11, 2.6.0.1.0-2.6.0.1.12, 2.6.0.2.0-2.6.0.2.9, 25.12.0.0.0-25.12.0.0.2) with Oracle before upgrading. Until patched, restrict interactive logon to the NMS infrastructure to trusted operators, remove or disable unnecessary low-privileged local accounts, and audit those accounts for unexpected data reads. These controls reduce exposure but can disrupt legitimate utility operations and require identity/account management overhead; they are compensating measures, not a substitute for the vendor fix.

Technical ContextAI · show details

Oracle Utilities Network Management System is a utility operations platform whose 'System Wide' component handles cross-application functions. The assessed CVSS vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N indicates the flaw is reachable only after an attacker obtains interactive logon to the underlying infrastructure with a low-privileged account; once there, no user interaction or special complexity is needed to read data the account should not access. Impact is limited to confidentiality (C:H), with no integrity or availability effect and no scope change. The source tags label it an authentication bypass, consistent with an access-control weakness that lets a low-privileged local user exceed intended data-read boundaries, but no CWE mapping or CPE data was supplied to pinpoint the exact code path. The affected ranges span six Oracle Utilities NMS release trains from 2.4.0.1.0 through 25.12.0.0.2.
