Exploitation Conditions

The target must be running Dell Secure Connect Gateway 5.0 Appliance prior to version 5.36.00.16 or the Application variant prior to version 5.36.00.00, and the management interface must be network-reachable by the attacker. No authentication credentials of any kind are required (PR:N) and no user interaction is required (UI:N). The primary limiting factor is the AC:H metric: the exploit requires a non-trivial precondition - the specific technical nature of this complexity (race condition, ordered request sequence, particular protocol state) is not disclosed in the public advisory, but it prevents fully automated mass exploitation. There is no indication from available data that a non-default configuration setting or specific feature enablement is required beyond the product being deployed in a network-accessible configuration.

Impact

The CVSS 8.1 score with vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H reflects an unauthenticated network-reachable critical function, but the AC:H metric is a meaningful moderating factor: exploitation is not trivially repeatable on demand and likely requires a specific precondition - such as a race condition, precise request ordering, or particular network posture - that limits the feasibility of mass automated scanning campaigns compared to AC:L vulnerabilities. No EPSS score is available in the provided data, restricting probabilistic exploitation forecasting; no CISA KEV listing and no public POC have been identified, which lowers immediate threat urgency somewhat. That said, the combination of PR:N (zero credentials required) and a full C:H/I:H/A:H impact on a remote-support gateway - which by design has privileged access to downstream managed systems - gives this vulnerability an outsized blast radius relative to its base score, and even a mid-sized municipal IT team in tczew deploying Dell SCG for infrastructure remote-support should treat this as a high-urgency patch before exploitation primitives become publicly available. Dell's confirmation of both the vulnerability and a patch strengthens confidence that this is a real, reproducible finding.

Exploit ScenarioDerived

An attacker with network access to the exposed Dell SCG management interface - reachable over the internet or an internal network segment - identifies the unauthenticated critical function endpoint through reconnaissance of known Dell SCG port and API patterns. The attacker satisfies the AC:H precondition (e.g., correct request sequence or timing) and submits a crafted unauthenticated request, gaining unauthorized administrative access to the gateway. From this position, the attacker can exfiltrate sensitive data, modify gateway configuration, or pivot to downstream systems managed through the SCG remote-support channel. No public exploit has been identified at time of analysis.

AnalysisAIv1 – Sep 07, 2026

Dell Secure Connect Gateway (SCG) 5.0 exposes a critical management function without any authentication requirement (CWE-306), enabling an unauthenticated remote attacker to achieve full confidentiality, integrity, and availability compromise against affected deployments. Both the Appliance variant (versions prior to 5.36.00.16) and the Application variant (versions prior to 5.36.00.00) are confirmed vulnerable per Dell advisory DSA-2026-382 and EUVD-2026-72375. No public exploit has been identified at time of analysis; Dell has released patches for both deployment forms.

RemediationAI

Upgrade Dell Secure Connect Gateway 5.0 Appliance to version 5.36.00.16 or later and the Application variant to version 5.36.00.00 or later, per Dell advisory DSA-2026-382 (https://www.dell.com/support/kbdoc/en-in/000503426/dsa-2026-382-security-update-for-dell-secure-connect-gateway-virtual-edition-multiple-vulnerabilities). If immediate patching cannot be completed, apply network-layer compensating controls: restrict access to the SCG management interface via firewall ACLs or VLAN segmentation so that only trusted administrative source IPs can reach it, and disable any internet-facing exposure of the appliance or application management port. Note that network restriction reduces the attack surface but does not eliminate the underlying unauthenticated endpoint; it must be followed by patching at the earliest maintenance window.

Technical ContextAI · show details

Dell Secure Connect Gateway 5.0 is an enterprise remote-support and connectivity gateway that facilitates secure remote management and support sessions for Dell infrastructure. The vulnerability is classified as CWE-306 (Missing Authentication for Critical Function), meaning one or more critical API or management-plane endpoints are reachable over the network without any credential requirement - the authentication layer is entirely absent, not merely bypassable. Two distinct deployment forms are affected, confirmed by CPE identifiers cpe:2.3:a:dell:secure_connect_gateway_5.0_-_appliance and cpe:2.3:a:dell:secure_connect_gateway_5.0_-_application. The CVSS vector of AV:N/AC:H/PR:N/UI:N indicates the unprotected function is network-exposed but requires a non-trivial exploitation condition (AC:H), such as a specific protocol state, request sequence, or timing window, which prevents fully automated opportunistic exploitation while still permitting determined attackers to achieve full triad impact.

DescriptionCVE.org

ell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains a Missing Authentication for Critical Function vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to unauthorized access.

Executive ViewAI

Why It Matters

Dell Secure Connect Gateway (SCG) 5.0 exposes management functions without authentication, allowing unauthenticated remote attackers to achieve full system compromise; no public exploit identified at time of analysis. Appliance versions prior to 5.36.00.16 and Application versions prior to 5.36.00.00 face immediate risk to data confidentiality, system integrity, and service availability. Urgent patching is required to restore baseline security controls.
