Exploitation Conditions

Exploitation requires an attacker on an adjacent network segment (AV:A - the vulnerability is not reachable across routed/internet paths, typically limiting it to the same management VLAN or L2 broadcast domain) who additionally holds high privileges on the application (PR:H - an already-authenticated administrative or equivalently privileged OpenManage Enterprise account). No user interaction is needed (UI:N). The affected scope is any Dell OpenManage Enterprise instance on a version prior to 4.8.0. These combined prerequisites - privileged authentication plus adjacent placement - are the principal limiting factors and markedly reduce realistic exploitability compared with the raw 6.1 score; there are no special feature or non-default-configuration conditions stated in the available sources, and the precise triggering request is not described in DSA-2026-467 as provided.

Impact

This is a moderate-severity issue (vendor CVSS 6.1) whose real-world urgency is tempered by its access requirements. The CVSS vector CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H establishes that exploitation requires adjacent network access (AV:A, not routable from the internet) and high privileges (PR:H, an already-authenticated high-privilege account), which substantially narrows the realistic attacker population to insiders or an adversary who has already compromised a privileged session on the management plane. No EPSS score is provided in the input, the CVE is not listed in CISA KEV, and no proof-of-concept or exploit reference is supplied, so there is no public exploit identified at time of analysis. The vuln.today decision label is 'this_month' - meaningful priority but below act_now/emergency - which is consistent with a high-privilege, adjacent-only flaw rather than a wormable remote bug. One notable internal inconsistency: the CVSS impact set is C:N/I:H/A:H (no confidentiality impact, high integrity and availability impact), yet the description states the outcome is 'Filesystem access for attacker,' which usually implies a read/confidentiality effect; this suggests the traversal is write/overwrite-oriented (enabling file modification or disruption) rather than file disclosure - verify the exact primitive with Dell advisory DSA-2026-467. Overall this is a legitimate patch-management item for Dell server-management environments, not a drop-everything emergency.

Exploit ScenarioDerived

An attacker who already holds a high-privilege account on a Dell OpenManage Enterprise instance (or has pivoted onto the adjacent management network segment) submits a crafted request containing directory-traversal sequences to a vulnerable handler, escaping the intended restricted directory to reach arbitrary filesystem paths. Per the CVSS impact (I:H/A:H), this most plausibly allows modifying or overwriting files on the appliance, affecting integrity and availability of the management platform. No public exploit identified at time of analysis, and the adjacent-network plus high-privilege requirements keep this out of reach of opportunistic remote attackers.

AnalysisAIv1 – Nov 02, 2026

Dell OpenManage Enterprise versions prior to 4.8.0 contain a path traversal flaw (CWE-22) that lets a high-privileged attacker on an adjacent network segment write to and delete files outside the intended restricted directory, producing a high integrity and availability impact on the appliance (CVSS 6.1, AV:A/AC:L/PR:H/UI:N/C:N/I:H/A:H). Exploitation requires an already-authenticated administrative-level OpenManage Enterprise account and L2-adjacent placement (same management VLAN or broadcast domain), which markedly limits realistic exposure; there is no public exploit identified at time of analysis and the issue is not in CISA KEV. The vendor has published advisory DSA-2026-467 covering the fix in version 4.8.0.

RemediationAI

Upgrade Dell OpenManage Enterprise to version 4.8.0 or later, as documented in Dell advisory DSA-2026-467 (https://www.dell.com/support/kbdoc/en-us/000523220/dsa-2026-467-security-update-for-dell-openmanage-enterprise-vulnerabilities); vendor-released patch: 4.8.0. No workarounds are given in the available advisory data. Because exploitation requires high application privileges plus adjacent network placement, interim risk reduction is best achieved by limiting who holds administrative OpenManage Enterprise accounts, reviewing those accounts for necessity, and restricting management-plane reachability to trusted administrative VLANs and hosts so that no untrusted segment is L2-adjacent to the appliance; note that network segmentation provides only partial protection while a privileged account remains usable against an unpatched instance.

Technical ContextAI · show details

The weakness is CWE-22, Improper Limitation of a Pathname to a Restricted Directory, meaning user-supplied path input is not sufficiently canonicalized or constrained before filesystem operations, allowing access to paths outside the intended directory tree. The affected product is Dell OpenManage Enterprise, the web-based datacenter systems-management console for Dell PowerEdge servers and related infrastructure; the wildcard CPE cpe:2.3:a:dell:openmanage_enterprise:*:*:*:*:*:*:*:* identifies all versions prior to 4.8.0 as in scope. The assessed vector (AV:A/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H) shows the flaw is reachable only from an adjacent network segment by a holder of high application privileges, with no user interaction and no confidentiality impact, but high integrity and availability impact - consistent with an attacker able to overwrite or remove appliance files. The specific request or interface that triggers the traversal is not described in DSA-2026-467 as provided, so the exact code path is unverified.
