Exploitation Conditions

Dell Alienware Command Center (a version prior to 6.14.54.0) must be installed on the victim's machine so that its custom URL scheme handler is registered. Exploitation is not fully unauthenticated: the CVSS vector specifies PR:L, so a low-privileged context is required, and UI:R means the victim must actively interact - typically opening or clicking an attacker-crafted link that invokes the vulnerable custom URL scheme. These limiting factors (required user interaction, required low-level privilege, and the need for AWCC to be present) substantially constrain real-world exploitation beyond what the network attack vector alone suggests. The precise conditions under which the authorization check is bypassed are not described in the available sources.

Impact

This is a low-severity issue by every available signal, and the signals are consistent rather than conflicting. The vendor CVSS base score is 3.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N): although the attack vector is network, exploitation requires low-level privileges (PR:L), requires victim user interaction (UI:R), and yields only a limited confidentiality impact with no integrity or availability impact (C:L/I:N/A:N) - consistent with a Client-Side Request Forgery / information-disclosure outcome rather than code execution. The vuln.today decision label is 'monitor', the lowest urgency tier, which aligns with the low base score. No EPSS probability was supplied, the CVE is not listed in CISA KEV, and no proof-of-concept or exploit reference appears in the input, so exploitation status is 'no public exploit identified at time of analysis.' The one missing-but-relevant datum is EPSS, but its absence does not change the picture: nothing here elevates this above a routine patch-on-schedule item. This is a genuinely low-priority, high-CVSS-it-is-not case - treat as a maintenance update.

Exploit ScenarioDerived

An attacker crafts a web page or message containing a link that invokes Dell Alienware Command Center's custom URL scheme, and lures a user who already has AWCC installed into opening it (UI:R). Because the custom URL scheme handler performs improper authorization, the crafted invocation causes the client to issue a forged request, resulting in limited information disclosure. No public exploit or PoC is identified at time of analysis.

AnalysisAIv1 – Nov 02, 2026

Client-side request forgery in Dell Alienware Command Center (AWCC) before 6.14.54.0 allows a low-privileged, remote attacker to make the application issue crafted requests on the victim's behalf, with impact scored as limited confidentiality exposure only (CVSS 3.5). Exploitation requires AWCC to be installed so its custom URL scheme handler is registered, a low-privileged context (PR:L), and victim interaction with an attacker-crafted link (UI:R), which substantially constrains real-world abuse. Every available signal rates this as low severity and the priority decision is monitor; no public exploit code has been identified at time of analysis and the issue is not in CISA KEV.

RemediationAI

Dell addresses this in AWCC 6.14.54.0; upgrading to that version or later is the primary fix, and the vendor advisory DSA-2026-429 (https://www.dell.com/support/kbdoc/en-us/000512248/dsa-2026-429-security-update-for-dell-alienware-command-center-6-x-for-multiple-vulnerabilities) is the authoritative source for download details and any additional affected 6.x builds. The available sources do not document a vendor-endorsed workaround, so installations that cannot be updated immediately should be prioritized for upgrade given the low severity and the prerequisites - AWCC must be present with its URL scheme handler registered, the attacker operates from a low-privileged context, and the victim must interact with a crafted link. Deployments are advised to track the Dell KBDoc for updated fix versions, since the advisory covers multiple vulnerabilities in the 6.x line.

Technical ContextAI · show details

The flaw is classified as CWE-939, Improper Authorization in Handler for Custom URL Scheme. AWCC registers a custom URI scheme with the operating system so that links using that scheme are dispatched to the application; the handler fails to properly authorize the request before acting on it, allowing an attacker-supplied URI to drive application behavior in the victim's context. The result is a client-side request forgery, reflected in the assessed vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N - network-reachable with low attack complexity, but gated by a low-privileged prerequisite and mandatory user interaction, with only a low confidentiality impact and no integrity or availability effect. The trigger conditions under which the authorization check is bypassed are not described in the available sources, and no CPE strings were supplied, so exact platform coverage is inferred only from the Dell advisory covering AWCC 6.x prior to 6.14.54.0.
