Product Overview
Two high-severity privilege escalation vulnerabilities have been identified in enterprise management utilities developed by Dell. These products are frequently deployed on corporate laptops and workstations to provide performance optimization and remote management capabilities. Because both tools interact closely with system services and hardware interfaces, they operate with elevated privileges and therefore become attractive targets for attackers seeking local privilege escalation.
Dell Optimizer is a system-tuning and performance optimization application that dynamically adjusts device behavior such as power consumption, application prioritization, audio optimization, and network performance. It runs several background services that communicate with hardware and system components.
Dell Command | Intel vPro Out-of-Band is a remote management utility that allows administrators to control enterprise endpoints through Intel vPro technologies. It enables features such as remote power management, firmware updates, remote diagnostics, and device configuration even when the operating system is not actively running.
Improper validation of executable components within these utilities may allow attackers with limited access to escalate privileges and execute code with SYSTEM-level permissions.

Technical Details
CVE-2026-25906
The vulnerability exists within a Dell Optimizer service responsible for launching helper executables that perform optimization tasks such as power tuning and network prioritization.
The service runs with elevated privileges and dynamically loads executable components during runtime. In vulnerable versions, insufficient validation of executable locations and file permissions may allow malicious files to be executed.
If writable directories exist within the executable search path used by the service, an attacker could introduce a malicious binary or dynamic library. When the service initializes or triggers an optimization process, the malicious component may be loaded and executed with SYSTEM privileges.
Because the Dell Optimizer service typically runs continuously, exploitation may occur automatically after the malicious file is introduced.
CVE-2026-24502
This vulnerability affects Dell Command | Intel vPro Out-of-Band services. The issue arises from an uncontrolled search path element used by the application during component initialization.
Certain service processes rely on system search paths to locate required libraries or executables. If the search path includes directories that can be modified by non-privileged users, a malicious library or binary could be placed within that directory.
During service execution, the malicious component may be loaded before the legitimate component due to path precedence. As the service runs with elevated privileges, the malicious code inherits these privileges.
This attack technique is commonly known as DLL search order hijacking or binary planting.
Affected Systems
Systems typically affected include Dell enterprise endpoints where the vulnerable utilities are preinstalled or deployed through enterprise management tools.
Common environments include:
- Dell Latitude enterprise laptops
- Dell Precision workstations
- Dell OptiPlex enterprise desktops
Corporate environments using centralized device management are more likely to deploy these utilities widely.
Potential Impact
Successful exploitation may allow attackers to gain SYSTEM-level access on affected endpoints. Once elevated privileges are obtained, attackers may perform various malicious activities including:
- Installation of persistent malware
- Creation of unauthorized administrator accounts
- Execution of arbitrary commands
- Modification of system security configurations
- Credential harvesting
- Deployment of lateral movement tools
- Establishment of remote access backdoors
Because these utilities operate with high privileges, exploitation may bypass several endpoint security restrictions.
Exploitation Scenario
A potential attack chain may involve the following stages:
- Initial access is obtained through phishing, malicious downloads, or compromised credentials.
- The attacker enumerates installed services and identifies vulnerable Dell utilities.
- Writable directories associated with service executable paths are located.
- A malicious DLL or executable is introduced into the writable directory.
- The service loads the malicious component during startup or normal operation.
- Arbitrary code executes with SYSTEM privileges.
- Persistence and lateral movement techniques may then be deployed.
Proof-of-Concept (Educational Purpose Only)
The following commands demonstrate how a payload executed by a vulnerable service could escalate privileges or create administrative access. These examples are intended only for controlled laboratory testing.
Example privilege escalation command:
net user securitytest Password123! /add
net localgroup administrators securitytest /add
Example command execution payload:
cmd.exe /c whoami > C:\temp\system_context.txt
Example PowerShell payload for launching elevated processes:
powershell -ExecutionPolicy Bypass -NoProfile -Command Start-Process cmd -Verb runAs
These commands demonstrate potential actions that could be executed once code runs with elevated privileges.

Detection
Detection should focus on monitoring service behavior, process creation events, and suspicious file placement within application directories.
Indicators of suspicious activity may include:
- Unexpected command shells launched by Dell service processes
- Unusual DLL loading activity
- Creation of new files within application installation directories
- Privilege escalation events involving standard user accounts
- Service processes spawning administrative tools
