DescriptionCVE.org

Dell Wyse Management Suite (WMS), versions prior to 2605.0.2, contain an Unrestricted Upload of File with Dangerous Type vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Remote Code Execution.

AnalysisAI

Remote code execution is achievable in Dell Wyse Management Suite (WMS) versions prior to 2605.0.2 via an unrestricted file upload vulnerability (CWE-434). A high-privileged remote attacker can upload a file with a dangerous type - such as a web shell or server-side script - to the WMS server, resulting in full code execution with the application's privileges. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold a high-privileged (administrative) account on the Dell WMS platform - this is the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) accurately reflects the risk profile: while the attack vector is network-accessible with low complexity, exploitation requires high-level privileges (administrative account), which significantly limits the realistic threat surface compared to unauthenticated RCE vulnerabilities. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained WMS administrative credentials - through phishing, credential stuffing, or insider access - authenticates to the WMS web console and navigates to a file upload function within the interface. The attacker uploads a crafted server-side script (e.g., a JSP web shell) that bypasses insufficient file type validation, then directly accesses the uploaded file via its URL, causing the application server to execute the payload and return a command shell running as the WMS service account. …
Remediation Upgrade Dell Wyse Management Suite to version 2605.0.2 or later, as documented in Dell security advisory DSA-2026-329 (https://www.dell.com/support/kbdoc/en-us/000493271/dsa-2026-329-security-update-for-dell-wyse-management-suite-wms-for-multiple-vulnerabilities). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, audit all deployed Dell Wyse Management Suite instances to identify versions prior to 2605.0.2 and document their network locations and criticality. …
