CVE-2026-41116: Dell Inventory Collector Client Link Following Vulnerability

Technical summary

CVE-2026-41116 is a Link Following (CWE-1386) vulnerability in Dell Inventory Collector Client prior to version 13.8.0. The flaw occurs when the application resolves file paths without properly validating whether intermediate components are symbolic links. An attacker with local user privileges can craft a symbolic link to redirect file write operations, bypassing intended access controls and achieving arbitrary file write capabilities. The CVSS 3.1 score of 6.3 reflects the local-only attack vector, high complexity requirement, and impact limited to integrity and availability of the affected system.

Business impact

Exploitation could allow a local attacker to modify or corrupt application files, configuration data, or system files accessible to the Dell Inventory Collector Client process. This may lead to service disruption, configuration tampering, installation of malicious configurations, or escalation of privileges if the client runs under elevated context. Organizations relying on Dell Inventory Collector for asset discovery and compliance reporting may experience data integrity issues or operational downtime during remediation.

Affected systems

Dell Inventory Collector Client versions prior to 13.8.0 are affected. No specific product families or enterprise deployments are enumerated in the vendor advisory; affected deployments should be identified through version inventory across managed endpoints. The vulnerability requires local access, limiting exposure to systems where untrusted local users or threat actors with physical/RDP access to enterprise endpoints are present.

Exploitability

Exploitation requires low-level local user privileges and cannot be executed remotely. The attacker must have the ability to create symbolic links in directories where the Inventory Collector Client performs file operations—typically within shared or world-writable locations on the endpoint. The high complexity factor (AC:H) suggests environmental prerequisites or race-condition timing are necessary, making opportunistic exploitation less likely than targeted attacks against specific high-value endpoints where an attacker already has established local presence.

Remediation

Upgrade Dell Inventory Collector Client to version 13.8.0 or later. Organizations should prioritize systems where the Inventory Collector Client runs with elevated privileges or on multi-user systems where lower-privileged accounts may exist. Interim mitigations include restricting local user access, disabling the Inventory Collector Client on endpoints not actively requiring asset discovery, or limiting its execution to scheduled windows with direct administrator oversight.

Patch guidance

Apply Dell's official update to Inventory Collector Client version 13.8.0 or later. Organizations should verify compatibility and test patches in a non-production environment before enterprise rollout. Dell's update should be obtained directly from Dell's support portal or official distribution channels. Coordinate patching with your asset management and inventory processes to ensure continuous visibility during update windows. Document the pre-patch and post-patch versions for audit purposes.

Detection guidance

Monitor for symbolic links being created in directories where Inventory Collector Client typically writes files (e.g., temporary directories, installation folders, or data repositories). Alert on file write operations by the Inventory Collector Client process that resolve to unexpected file paths outside normal operational directories. Endpoint detection and response (EDR) tools capable of symbolic link tracking will provide highest fidelity. File integrity monitoring (FIM) on configuration and binary directories associated with the Inventory Collector Client can identify unauthorized modifications. Check process execution logs for Dell Inventory Collector Client invocations immediately following local user login or privilege elevation events.

Why prioritize this

Although the CVSS base score is 6.3 (MEDIUM), this vulnerability warrants near-term remediation because it enables arbitrary file write on Windows or UNIX endpoints where Inventory Collector Client operates—a foundational asset discovery tool in many enterprises. The requirement for local access significantly reduces external threat surface, but the high integrity and availability impact means compromised endpoints could corrupt asset inventory data or disable discovery mechanisms. Organizations with multi-tenant or high-turnover user bases should prioritize patching. Lack of KEV status does not indicate low risk; local privilege escalation chains in enterprise environments can make this vulnerability part of a broader attack path.

Risk score, explained

The CVSS 3.1 score of 6.3 (MEDIUM) reflects: Attack Vector Local (AV:L) — exploitation requires existing system access; Attack Complexity High (AC:H) — environmental conditions or precise timing are required; Privileges Required Low (PR:L) — a standard user account is sufficient; User Interaction None (UI:N) — no social engineering or user action needed; Confidentiality None (C:N) — no direct information disclosure; Integrity High (I:H) — arbitrary file write can corrupt or replace critical data; Availability High (A:H) — modified files can degrade or disable the application. Organizations with security-sensitive asset management processes may view the impact as higher in context, even though the base score is MEDIUM.
