2 techniques across 2 tactics: Initial Access, Execution

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

Exploitation Conditions

The attacker must possess a valid low-privileged account on the Dell OpenManage Enterprise web interface (confirmed by PR:L in the CVSS vector) - unauthenticated exploitation is not possible. A separate victim user must actively interact with the page or view where the injected script is rendered (confirmed by UI:R), meaning the attack cannot be fully automated against a passive target. The OpenManage Enterprise web interface must be network-accessible to the attacker (AV:N). Exploitation is further limited by: (1) the need to obtain even a low-privileged credential, which may require prior phishing or credential theft; (2) the dependency on a victim - typically a higher-privileged user - visiting the poisoned page; and (3) unchanged scope (S:U), meaning the attacker cannot leverage this XSS to escape the web application context into the host OS.

Impact

The CVSS 4.6 Medium score is consistent with the constraint set: network-accessible (AV:N), low complexity (AC:L), but requiring a low-privileged account (PR:L) and victim interaction (UI:R). These two limiting factors - authentication and user interaction - meaningfully reduce real-world exploitation probability relative to a fully unauthenticated, no-interaction XSS. No EPSS score was provided in the input data, so probability-based prioritization cannot be applied. The absence of both a CISA KEV listing and any reported POC further supports a non-urgent posture for organizations running patched infrastructure. For environments where OpenManage Enterprise is exposed to internal threat actors (e.g., shared administrative consoles, contractor-accessible networks), the PR:L prerequisite is weaker than it appears, as low-privileged accounts may be widely provisioned. S:U and A:N confirm no privilege escalation or availability impact pathway exists through this vector.

Exploit ScenarioDerived

A low-privileged attacker with a valid OpenManage Enterprise account injects a malicious JavaScript payload into a data field - such as a device label, alert annotation, or profile name - that is later rendered in the management console viewed by an administrator. When the administrator navigates to the affected view, the script executes silently in their browser, exfiltrating their session cookie or capturing sensitive infrastructure data to an attacker-controlled endpoint. No public exploit code is known at time of analysis, but the low technical complexity of XSS attacks means skilled attackers could develop one independently.

AnalysisAIv1 – Aug 19, 2026

Cross-site scripting in Dell OpenManage Enterprise (all versions prior to 4.7.0) enables a low-privileged remote authenticated attacker to inject malicious JavaScript that executes in the browsers of other users, leading to information exposure such as session token theft or disclosure of management data. The CVSS vector confirms network accessibility with low attack complexity, but exploitation requires both a valid low-privileged account and a separate victim who interacts with the injected content. No public exploit code or CISA KEV listing has been identified at time of analysis, placing this in a monitor-and-patch rather than emergency-response category.

RemediationAI

Upgrade Dell OpenManage Enterprise to version 4.7.0 or later, as specified in Dell advisory DSA-2026-359 (https://www.dell.com/support/kbdoc/en-us/000500910/dsa-2026-359-security-update-for-dell-openmanage-enterprise-vulnerabilities). If immediate patching is not feasible, restrict access to the OpenManage Enterprise web interface to trusted administrative networks or VPN-only segments to reduce the pool of potential low-privileged attackers - note this does not eliminate the vulnerability but reduces the attack surface by limiting who can hold a valid account. Additionally, enforce strict Content Security Policy (CSP) headers at the reverse proxy or load balancer level to constrain script execution origins, though this is a defense-in-depth measure and not a substitute for patching. Audit low-privileged account assignments and remove unnecessary accounts to limit PR:L exposure.

Technical ContextAI · show details

Dell OpenManage Enterprise is a centralized data center infrastructure management platform providing hardware lifecycle, monitoring, and configuration capabilities through a web interface. The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation), indicating that user-controlled input is insufficiently sanitized before being embedded into HTML responses rendered by victim browsers. The CPE cpe:2.3:a:dell:openmanage_enterprise:*:*:*:*:*:*:*:* covers all versions of the application tier prior to 4.7.0. The CVSS unchanged scope metric (S:U) indicates the XSS impact is confined to the web application's security context and does not break out into the underlying OS or adjacent systems. The exact XSS subtype - reflected versus stored - is not specified in the available data.

Attack Technique

Cross-Site Scripting occurs when an application accepts untrusted data and sends it to a web browser without proper validation or encoding.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
