CVE-2025-36580 Overview
CVE-2025-36580 is a stored cross-site scripting (XSS) vulnerability in Dell Wyse Management Suite versions prior to WMS 5.2. The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. An authenticated attacker with high privileges and remote access can inject script content that executes in the browser of a targeted user who interacts with the affected page. Successful exploitation requires user interaction and can lead to script injection within the management console context.
Critical Impact
An authenticated high-privileged attacker can inject malicious scripts into the Wyse Management Suite web interface, compromising session confidentiality and integrity for administrators who view the crafted content.

Technical Details for CVE-2025-36580
Vulnerability Analysis
Dell Wyse Management Suite is a centralized platform for managing Wyse thin clients and endpoints. The vulnerability exists in a web page generation routine that reflects or stores user-controlled data without adequate output encoding. When the affected page renders, injected HTML or JavaScript executes in the victim's browser under the origin of the management console.
Because the CVSS scope is changed, the impact crosses trust boundaries. Script execution occurs in the context of the administrator session, enabling actions such as session token theft, unauthorized console navigation, or manipulation of rendered content presented to other operators.
Root Cause
The root cause is improper neutralization of input during web page generation [CWE-79]. The affected component fails to apply context-aware output encoding for user-controllable fields before writing them into HTML responses. As a result, characters such as <, >, and " retain their control semantics when interpreted by the browser.
Attack Vector
Exploitation requires network access to the Wyse Management Suite web interface and authentication as a high-privileged user. The attacker submits crafted input containing script payloads through an input field or parameter processed by the vulnerable page. A second user, typically another administrator, must load the affected page for the payload to execute. This user interaction requirement limits opportunistic exploitation but does not preclude targeted attacks against operator accounts.
No public proof-of-concept exploit is available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-36580
Indicators of Compromise
- Unexpected <script>, onerror=, or javascript: tokens present in Wyse Management Suite configuration fields, group descriptions, or asset metadata
- Web server access logs showing POST or PUT requests containing HTML-encoded or raw script payloads to management endpoints
- Administrator sessions performing actions outside normal workflow immediately after loading a specific console page
Detection Strategies
- Inspect stored records in the Wyse Management Suite database for HTML control characters in fields intended to hold plain text
- Deploy a web application firewall rule set that flags reflected and stored XSS payload patterns targeting /wms/ and related management URIs
- Correlate authentication events with unusual administrative API calls that follow console page rendering
Monitoring Recommendations
- Enable verbose audit logging on the Wyse Management Suite server for privileged user actions and forward logs to a centralized SIEM
- Monitor for high-privileged account creation, permission changes, or credential exports occurring shortly after browsing configuration pages
- Alert on browser-driven requests originating from administrator workstations that deviate from documented administrative workflows
How to Mitigate CVE-2025-36580
Immediate Actions Required
- Upgrade Dell Wyse Management Suite to version 5.2 or later as instructed in Dell Security Advisory DSA-2025-226
- Restrict access to the Wyse Management Suite web console to trusted management networks only
- Review and audit high-privileged accounts, rotating credentials for any accounts suspected of compromise
Patch Information
Dell has released a fixed build in Wyse Management Suite 5.2. Administrators should follow the upgrade procedure documented in Dell Security Advisory DSA-2025-226 and validate that the deployed version reports 5.2 or higher after upgrade.
Workarounds
- Limit console access to a small set of jump hosts and enforce strong authentication for administrator accounts
- Apply the principle of least privilege so that day-to-day operators do not hold roles required to exploit this vulnerability
- Require administrators to use isolated browser profiles or dedicated management workstations when interacting with the Wyse Management Suite console
