CVE-2026-91898 in Alienware Command Center
Summary
by MITRE • 11/02/2026
Dell Alienware Command Center (AWCC), versions prior to 6.14.54.0, contain an Improper Verification of Cryptographic Signature vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Arbitrary Code Execution and Elevation of Privilege.

The Dell Alienware Command Center (AWCC), specifically versions prior to 6.14.54.0, suffers from a critical security flaw classified as an Improper Verification of Cryptographic Signature. This vulnerability stems from the software's failure to rigorously validate digital signatures associated with updates or components before execution. In modern operating systems and application architectures, cryptographic signature verification serves as a primary defense mechanism against tampering and unauthorized modifications. By neglecting this essential check, AWCC inadvertently trusts code that has not been authenticated by the vendor, thereby bypassing integrity controls designed to ensure software authenticity.
An attacker with adjacent network access can exploit this weakness without requiring prior authentication credentials. The lack of signature verification allows malicious actors to inject or substitute legitimate application components with modified versions containing harmful payloads. Because AWCC operates with elevated privileges to manage hardware settings and system configurations, successfully exploiting this flaw enables Arbitrary Code Execution on the target machine. This means an attacker can run any code they choose within the context of the affected process, effectively gaining full control over the compromised system segment.
The operational impact of this vulnerability is severe due to its potential for Elevation of Privilege. Since AWCC typically runs with administrative rights to interact deeply with hardware drivers and BIOS settings, arbitrary code execution translates directly into high-level system access. An attacker could install persistent backdoors, exfiltrate sensitive data, or pivot further into the local network using the compromised machine as a foothold. This scenario is particularly dangerous in environments where gaming PCs are connected to corporate networks or contain valuable intellectual property, as it bypasses traditional perimeter defenses that rely on authentication requirements.
From a classification perspective, this vulnerability aligns with CWE-347, which describes Improper Verification of Cryptographic Signature. It also maps closely to MITRE ATT&CK techniques related to Software Deployment and Packaging, specifically the sub-technique for Supply Chain Compromise or Binary Patching, where attackers modify legitimate software binaries to execute malicious code. The adjacent network access requirement places this in a context similar to lateral movement scenarios if an attacker has already breached part of the local area network but lacks direct user credentials on the specific endpoint.
Mitigation strategies must prioritize immediate patching by updating Dell Alienware Command Center to version 6.14.54.0 or later, where these signature verification checks have been corrected and hardened. In environments where immediate patching is not feasible due to operational constraints, network segmentation should be enforced to restrict adjacent access from untrusted zones. Additionally, implementing strict application whitelisting policies can prevent the execution of unsigned binaries, providing a compensating control that mitigates the risk even if the underlying vulnerability remains present in older versions until they are retired or replaced.
