CVE-2026-24509: Dell Alienware Command Center DoS Flaw

CVE-2026-24509 Overview

Dell Alienware Command Center (AWCC), versions prior to 6.12.24.0, contains an Improper Access Control vulnerability (CWE-284). A low privileged attacker with local access could potentially exploit this vulnerability, leading to Denial of Service. This access control flaw allows attackers to manipulate system resources in unintended ways, potentially disrupting normal operations of the Alienware Command Center software.

Critical Impact

Local attackers with low privileges can exploit improper access controls to cause denial of service conditions on affected Dell Alienware systems.

Affected Products

• Dell Alienware Command Center (AWCC) versions prior to 6.12.24.0

Technical Details for CVE-2026-24509

Vulnerability Analysis

This vulnerability stems from improper access control mechanisms within Dell Alienware Command Center. The software fails to properly restrict access to certain operations or resources, allowing a low privileged local attacker to perform actions that should require elevated permissions. Given the local attack vector with high complexity requirements, exploitation requires the attacker to already have local system access and specific conditions to be met for successful exploitation.

The improper access control can result in both limited integrity and availability impacts, enabling attackers to potentially modify certain data and cause service disruptions. While the vulnerability does not expose confidential information, the denial of service impact could disrupt gaming and system management functionality that AWCC provides to Alienware users.

Root Cause

The root cause of CVE-2026-24509 is classified under CWE-284 (Improper Access Control). The Alienware Command Center application does not properly enforce access control policies, allowing unauthorized operations by users who should not have the necessary permissions. This typically occurs when software fails to validate user privilege levels before executing sensitive operations or accessing protected resources.

Attack Vector

The attack vector for this vulnerability is local, requiring the attacker to have existing access to the affected system. The exploitation involves:

1. An attacker gains low-privilege local access to a system running a vulnerable version of Dell Alienware Command Center
2. The attacker identifies operations or resources within AWCC that lack proper access control verification
3. By exploiting these improper access controls, the attacker can cause denial of service conditions
4. The high attack complexity indicates that specific conditions must be present for successful exploitation

The vulnerability does not require user interaction, meaning exploitation can occur without any action from the system's legitimate user once the attacker has local access.

Detection Methods for CVE-2026-24509

Indicators of Compromise

• Unexpected crashes or service disruptions of Dell Alienware Command Center application
• Anomalous behavior from AWCC-related processes or services
• Event logs showing access violations or permission errors related to AWCC components

Detection Strategies

• Monitor Windows Event Logs for unusual activity or errors associated with Alienware Command Center processes
• Implement application whitelisting and monitor for unauthorized access attempts to AWCC components
• Deploy endpoint detection solutions capable of identifying access control bypass attempts

Monitoring Recommendations

• Enable verbose logging for Dell Alienware Command Center if available
• Monitor system stability and resource usage for signs of denial of service conditions
• Track software version inventory to identify systems running vulnerable AWCC versions

How to Mitigate CVE-2026-24509

Immediate Actions Required

• Update Dell Alienware Command Center to version 6.12.24.0 or later immediately
• Audit local user accounts and remove unnecessary low-privileged access where possible
• Review and restrict local access to systems running Alienware Command Center until patched

Patch Information

Dell has released a security update addressing this vulnerability. Users should update to Dell Alienware Command Center version 6.12.24.0 or later. For detailed patch information and download instructions, refer to the Dell Security Advisory DSA-2026-093.

Workarounds

• Restrict local user access to systems running vulnerable versions of AWCC until patching is complete
• Implement application control policies to limit which users can interact with AWCC components
• Consider temporarily disabling non-essential AWCC functionality if denial of service impacts are observed
