CVE-2026-81469: Dell Inventory Collector Privilege Escalation

CVE-2026-81469 Overview

CVE-2026-81469 is an unquoted search path vulnerability [CWE-428] affecting Dell Inventory Collector Client versions prior to 15.0.0. The flaw allows a low-privileged local attacker to place a malicious executable in a directory searched before the intended binary. When the affected Dell service executes, Windows resolves the unquoted path to the attacker-controlled binary, resulting in code execution under the service account.

Critical Impact
Successful exploitation grants local attackers code execution and privilege escalation, potentially reaching SYSTEM-level access on affected Windows endpoints.

Affected Products

Dell Inventory Collector Client versions prior to 15.0.0
Dell SupportAssist for PCs (Home and Business), per DSA-2026-381
Dell Optimizer, Dell Trusted Device, and Dell Command Update, per DSA-2026-381

Technical Details for CVE-2026-81469

Vulnerability Analysis

The vulnerability stems from Dell Inventory Collector Client registering a Windows service or scheduled task with an unquoted file path that contains spaces. Windows parses such paths from left to right, attempting to execute each intermediate token as a standalone executable before falling back to the intended target. An attacker who can write to a parent directory in the search sequence can drop a malicious binary that Windows will invoke instead of the legitimate Dell component.

Exploitation requires local access and low privileges but no user interaction. The malicious binary executes in the security context of the service, which typically runs elevated. This yields both arbitrary code execution and privilege escalation in a single step.

Root Cause

The root cause is improper quoting of the service executable path during installation of Dell Inventory Collector Client. When a service ImagePath value such as C:\Program Files\Dell\Inventory Collector\ic.exe is registered without surrounding quotes, Windows treats spaces as argument delimiters. This behavior is classified under [CWE-428: Unquoted Search Path or Element].

Attack Vector

An attacker with local, low-privileged access identifies the vulnerable service and its unquoted ImagePath. The attacker writes a malicious executable such as C:\Program Files\Dell\Inventory.exe if directory permissions permit, or leverages another writable parent directory in the path. On the next service start, reboot, or scheduled task trigger, Windows loads the attacker binary with the service's elevated privileges. Public exploit code is not currently listed, and the vulnerability is not present in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-81469

Indicators of Compromise

Unexpected executables placed in parent directories of Dell service paths, such as C:\Program.exe or C:\Program Files\Dell\Inventory.exe.
Windows service processes spawning from non-standard binaries outside the intended Dell installation directory.
New or modified files in C:\Program Files\Dell\ written by non-administrative users.

Detection Strategies

Enumerate Windows services and scheduled tasks and flag entries where ImagePath contains spaces and is not enclosed in quotes.
Audit directory access control lists (ACLs) on all parent folders in Dell service paths to identify writable locations for low-privileged users.
Correlate process creation events (Windows Event ID 4688 or Sysmon Event ID 1) with parent processes matching services.exe and image paths outside expected Dell directories.

Monitoring Recommendations

Monitor file creation events in C:\, C:\Program Files\, and Dell installation subdirectories for unexpected .exe writes.
Alert on service configuration changes affecting Dell Inventory Collector, SupportAssist, Optimizer, Trusted Device, and Command Update.
Track privilege escalation patterns where a low-privileged user session precedes SYSTEM-context process execution originating from a Dell service path.

How to Mitigate CVE-2026-81469

Immediate Actions Required

Upgrade Dell Inventory Collector Client to version 15.0.0 or later, as instructed in DSA-2026-381.
Update associated products including Dell SupportAssist, Dell Optimizer, Dell Trusted Device, and Dell Command Update to the fixed releases listed in the vendor advisory.
Inventory endpoints running affected Dell software and prioritize patching systems where non-administrative users have interactive access.

Patch Information

Dell has released fixed versions addressing CVE-2026-81469. See the Dell Security Update DSA-2026-381 for product-specific fixed versions and download locations.

Workarounds

Restrict write permissions on C:\ and C:\Program Files\ parent directories to prevent low-privileged users from creating executables in service search paths.
Manually correct affected service ImagePath registry values by enclosing the full path in double quotes until the vendor patch is applied.
Disable or stop the Dell Inventory Collector service on systems that do not require it, pending remediation.
