Vulnerability AssessmentAI

Exploitation Exploitation requires a valid high-privileged (administrator-level) account on the Dell WMS console with remote network access to the application. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) reflects a network-accessible attack with low complexity but requiring high privileges - placing this in a meaningful risk tier for organizations where administrative credentials may be shared, reused, or phishable. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained high-privileged WMS credentials - through phishing, credential reuse, or insider access - authenticates to the WMS web console remotely over the network. They navigate to a file upload feature within the application and upload a malicious file (e.g., a JSP web shell or executable) without server-side type validation blocking it. …
Remediation Upgrade Dell Wyse Management Suite to version 2605.0.2 or later, as directed by Dell 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 Dell Wyse Management Suite deployments to identify systems running versions prior to 2605.0.2 (per DSA-2026-329) and restrict WMS console access to essential administrators pending remediation. …
