The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Exploitation requires two concrete, compounding prerequisites both reflected in the CVSS vector: (1) the attacker must already hold high-privileged/administrative access to the Dell OpenManage Enterprise console (PR:H), and (2) the attacker must have adjacent-network access (AV:A), meaning a position on the same logical network segment - typically the server management or out-of-band network - rather than arbitrary remote internet access. No user interaction is required (UI:N) and attack complexity is low (AC:L) once those preconditions are met. These two requirements - pre-existing admin privilege and adjacent-network reach - are the principal factors limiting realistic exploitation, confining the threat largely to insiders or an actor who has already compromised the management network. The affected scope is OpenManage Enterprise versions prior to 4.8.0; the specific configuration or feature that exposes the path-traversal is not described in the available sources.

Impact

This is a moderate-severity, vendor-reported issue (Dell DSA-2026-467, CVSS 6.1) that signals as a manageable, scheduled-patch priority rather than an emergency. The CVSS vector itself substantially constrains real-world risk: AV:A limits the attacker to an adjacent network position (same logical L2/management segment, not arbitrary internet reach), and PR:H requires the attacker to already hold high/administrative privileges on the OpenManage Enterprise console. An actor meeting the PR:H precondition is already highly trusted, which materially lowers the marginal impact of this flaw. No EPSS score, CISA KEV listing, or public PoC/exploit reference is present in the supplied data, and exploitation status is therefore 'no public exploit identified at time of analysis.' The vuln.today decision label is 'this_month,' consistent with a real but non-urgent fix window. One internal inconsistency should be noted for verification: the description states the outcome is 'Filesystem access for attacker' (which typically implies a confidentiality/read impact), yet the Dell CVSS vector sets C:N while rating I:H/A:H - the mechanism by which path traversal yields integrity and availability impact rather than confidentiality is not explained in the available sources; verify the exact impact with Dell.

Exploit ScenarioDerived

An attacker who has already obtained high-privileged (administrative) access to a Dell OpenManage Enterprise console, and who sits on an adjacent network segment such as the server management/out-of-band network, submits a request containing crafted path-traversal sequences to reach files outside the intended restricted directory. No public exploit code or PoC reference is identified in the available data, and the specific feature or endpoint that mishandles the pathname is not described in the sources.

AnalysisAIv1 – Nov 02, 2026

Path traversal (CWE-22) in Dell OpenManage Enterprise versions prior to 4.8.0 allows an attacker who already holds high-privileged console access and sits on an adjacent network segment to escape the intended restricted directory and reach filesystem locations, driving integrity and availability impact (CVSS 3.1: 6.1, AV:A/AC:L/PR:H/UI:N/C:N/I:H/A:H). The two compounding prerequisites - pre-existing administrative privilege and a position on the same logical network segment, typically the server-management or out-of-band network - are what bound real-world exposure to insiders or an actor who has already compromised the management network, rather than to arbitrary internet attackers. No public exploit has been identified at time of analysis, and the issue is tracked as a scheduled, this-month patch priority rather than an emergency.

RemediationAI

Vendor-released fix: upgrade Dell OpenManage Enterprise to 4.8.0 or later, as versions prior to 4.8.0 are affected; confirm the target build against Dell advisory DSA-2026-467 at https://www.dell.com/support/kbdoc/en-us/000523220/dsa-2026-467-security-update-for-dell-openmanage-enterprise-vulnerabilities before and after upgrading. Until the upgrade is scheduled, exposure is governed by the two prerequisites in the assessed vector, so reducing the population of high-privileged console accounts and tightening which network segments can reach the appliance on the management/OOB side lowers practical risk; the trade-off is reduced administrative convenience and more constrained remote management workflows. No public exploit has been identified at time of analysis, and the vendor advisory should be checked for any additional guidance specific to this defect.

Technical ContextAI · show details

The flaw is classified as CWE-22, Improper Limitation of a Pathname to a Restricted Directory, meaning user-supplied path input is not adequately constrained to the intended directory before being used in filesystem operations, allowing traversal outside that boundary. Dell's advisory (DSA-2026-467) covers the OpenManage Enterprise management appliance, identified in the CPE data as cpe:2.3:a:dell:openmanage_enterprise with all versions below 4.8.0 affected. The CVSS vector is the clearest guide to the threat model: PR:H means the attacker must already hold administrative privilege on the console, AV:A means network reach is limited to an adjacent segment such as the management/OOB network, AC:L indicates no unusual conditions are needed once those preconditions are satisfied, and UI:N means no victim action is required. The resulting impact is scored as no confidentiality loss but high integrity and availability loss (C:N/I:H/A:H), consistent with filesystem access that can alter or disrupt managed content. The specific feature, endpoint, or parameter that exposes the traversal is not described in the available sources, and the trigger should be treated as unconfirmed pending the Dell advisory detail.
