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

Exploitation Conditions

Exploitation targets the Dell OpenManage Enterprise web console (versions prior to 4.8.0) and requires victim interaction (UI:R): a user - in practice an authenticated OME operator/administrator viewing the affected web page - must load or click attacker-supplied content for the injected script to execute. The attacker themselves needs no credentials (PR:N) and only remote network reachability to the console. Limiting factors that reduce real-world risk: the dependency on a privileged user's interaction, the high attack complexity (AC:H) indicating non-trivial or not-fully-attacker-controlled trigger conditions, and the fact that the specific feature, parameter, or page that reflects the unneutralized input is not described in the available sources. Upgrading to version 4.8.0 is the remediation named by the Dell advisory.

Impact

This is a moderate-priority issue, not a top-tier emergency. The CVSS 3.1 vector (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N, base 6.8) describes a network-reachable, unauthenticated (PR:N) cross-site scripting flaw, but two signals pull the real-world risk down: AC:H indicates the attacker does not fully control the conditions needed to trigger it, and UI:R requires a victim - in practice an authenticated OpenManage Enterprise operator/admin - to interact (click a crafted link or load attacker-influenced content). The vuln.today decision label is 'this_month', consistent with a serious-but-not-drop-everything priority. There is no CISA KEV listing and no EPSS score in the supplied data, so there is no evidence of active or probable widespread exploitation; exploitation status is 'no public exploit identified at time of analysis'. One signal is internally inconsistent and should be verified with the vendor: the description states only 'Information tampering' (an integrity effect), yet Dell's vector asserts C:H/I:H - the high confidentiality rating is not explained by the description, which typically for XSS would reflect session/token theft in the victim's browser rather than a direct server-side data read. No SSVC decision-point data (automatable, technical impact) was provided. Net: a genuine, patch-worthy flaw whose practical exploitation hinges on social-engineering a privileged user, which materially limits mass exploitation.

Exploit ScenarioDerived

An attacker crafts a malicious URL or input that, when processed by Dell OpenManage Enterprise's web interface, injects script that executes in the browser of an authenticated administrator who is lured into clicking it. Because success requires both the specific (undescribed) trigger conditions (AC:H) and victim interaction (UI:R), the attacker most likely relies on phishing or a watering-hole link aimed at console operators. No public exploit code or PoC reference was provided in the source data.

AnalysisAIv1 – Nov 02, 2026

Cross-site scripting in Dell OpenManage Enterprise versions prior to 4.8.0 allows an unauthenticated remote attacker to inject script that executes in the browser session of an operator or administrator who loads attacker-supplied content in the web console, potentially tampering with information viewed or acted upon in that session. The attacker needs network reachability to the console but no credentials (PR:N), while successful execution depends on victim interaction (UI:R) and non-trivial trigger conditions (AC:H); the specific page, parameter or feature that reflects the unneutralized input is not described in the available sources. No public exploit has been identified at time of analysis and the issue is not in CISA KEV; our assessment rates it a moderate-priority item (this_month) with scope-changed but low confidentiality and integrity impact and no availability impact, and Dell's advisory names upgrading to 4.8.0 as the remediation.

RemediationAI

Vendor-released patch: 4.8.0 - Dell's advisory DSA-2026-467 (https://www.dell.com/support/kbdoc/en-us/000523220/dsa-2026-467-security-update-for-dell-openmanage-enterprise-vulnerabilities) names upgrading Dell OpenManage Enterprise to version 4.8.0 as the remediation, so any deployment running a build below 4.8.0 should be scheduled for that upgrade within the current monthly maintenance window consistent with the moderate priority assigned to this issue. No workaround, configuration toggle or compensating control for this specific defect is described in the available sources, and no third-party patch or mitigation guidance was supplied, so the vendor upgrade is the only remediation path supported by the evidence at time of analysis.

Technical ContextAI · show details

The flaw is CWE-79, improper neutralization of input during web page generation, in the Dell OpenManage Enterprise web console - the browser-based management interface used to administer Dell PowerEdge server fleets. The vulnerable component is the web application layer, and the CPE cpe:2.3:a:dell:openmanage_enterprise:*:*:*:*:*:*:*:* is a wildcard covering all releases before the 4.8.0 fixed version rather than a single build. Because the sources do not identify which page, parameter or request reflects or stores the attacker-influenced input, the trigger is not described in the available sources, and it is unverified whether the issue is reflected, stored or DOM-based; the only exploitation detail the evidence supports is that a victim must interact with attacker-supplied content in the console for the script to run. Our assessed vector (AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N) treats this as remotely reachable without attacker credentials, gated by victim interaction and by high attack complexity indicating non-trivial or not-fully-attacker-controlled trigger conditions, with a scope change and low confidentiality/integrity consequences rather than the higher impact figures carried in the vendor-facing score of 6.8. In practice the interaction prerequisite means the party who must be induced to load the crafted content is an authenticated OME operator or administrator, which caps realistic exposure to environments where untrusted content reaches a privileged console session.
