Local logon required (AV:L) with a standard user account (PR:L); symlink primitive is reliable (AC:L) and the privileged WMS service operation yields full CIA impact on the host.

DescriptionCVE.org

Dell Wyse Management Suite (WMS), versions prior to WMS 2605, contain an Improper Link Resolution Before File Access vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Unauthorized access.

AnalysisAI

Local privilege-bound symlink abuse in Dell Wyse Management Suite (WMS) versions prior to 2605 allows a low-privileged local user to gain unauthorized access to files or resources they should not reach. The flaw is rooted in improper link resolution before file access (CWE-59), and while no public exploit has been identified at time of analysis, the CVSS 7.8 score reflects full confidentiality, integrity, and availability impact once the local prerequisite is met.

Technical ContextAI

Dell Wyse Management Suite is an on-premises and cloud management platform used by enterprises to provision, configure, and monitor Wyse thin clients and ThinOS endpoints. The underlying weakness, CWE-59 (Improper Link Resolution Before File Access, also known as 'Link Following'), occurs when a privileged process operates on a file path without first verifying that the path does not traverse a symbolic link or junction created by an unprivileged user. In practice, a WMS service process running with elevated rights likely opens, writes to, or deletes a file in a predictable location (logs, temp, working directories) where a lower-privileged local user can pre-stage a symlink, causing the privileged process to act on an attacker-chosen target. The CPE cpe:2.3:a:dell:wyse_management_suite_(wms):*:*:*:*:*:*:*:* covers all WMS application versions, and Dell's fix lands in WMS 2605.

RemediationAI

Vendor-released patch: upgrade Dell Wyse Management Suite to version 2605 or later per Dell DSA-2026-247 (https://www.dell.com/support/kbdoc/en-us/000472001/dsa-2026-247), which is the primary and recommended fix. Until WMS 2605 can be deployed, restrict interactive and remote-shell logon to the WMS server to administrators only - removing low-privileged local accounts eliminates the AV:L/PR:L precondition, at the cost of reducing operational separation of duties; additionally, audit and tighten ACLs on WMS installation, log, and temp directories (typically under the WMS program data path) so non-admin users cannot create files or symbolic links there, and consider disabling the Windows SeCreateSymbolicLinkPrivilege for non-administrator users on the WMS host to block the symlink primitive entirely, accepting that some developer tooling on that host may break.
