Exploitation Conditions

Exploitation requires the attacker to already possess high-privilege (administrative-level) authenticated access to the Dell SCG Policy Manager, per the CVSS PR:H metric - this is the primary limiting factor and means it is not exploitable by unauthenticated or low-privileged remote users. Given SSRF (CWE-918), the practical additional condition is a reachable request-handling feature that accepts or processes a URL/host the attacker can control, with the appliance having network paths to internal resources worth reaching; the scope change (S:C) indicates the forged requests can impact systems beyond the vulnerable component. No user interaction is needed (UI:N), and the vector is network-reachable (AV:N), but the high-privilege prerequisite substantially narrows realistic exploitation to insiders or attackers who have already compromised an admin account.

Impact

Signals here are largely coherent and point to a moderate, non-urgent priority despite the 8.7 'High' base score. The CVSS vector (AV:N/AC:L/PR:H/UI:N/S:C) describes a network-reachable, low-complexity SSRF, but crucially requires high privileges (PR:H) - so this is not an unauthenticated internet-facing bug. All exploitation signals agree with a lower real-world urgency: EPSS is only 0.20% (9th percentile), there is no CISA KEV listing, and no public exploit was identified, so exploitation status is 'no public exploit identified at time of analysis.' CISA's SSVC framework reinforces this: Exploitation=none and Automatable=no, meaning no observed or easily-scalable exploitation, even though Technical Impact=total (consistent with the scope change and C:H/I:H). The one notable conflict is version data: the description states the fix is 'prior to 5.34.00.16' while the EUVD/ENISA feed lists '<5.36.00.16 or later' - verify the exact fixed version against the Dell DSA-2026-385 advisory before remediation. Net: a genuine high-impact flaw gated behind existing high-privilege access, best treated as important-but-not-emergency patching rather than drop-everything.

Exploit ScenarioDerived

An attacker who already holds high-privilege (administrative) access to the Dell SCG Policy Manager issues a crafted request that the server processes, coercing it into making attacker-controlled requests to internal network resources. This yields information disclosure, access to otherwise unreachable internal services, and bypass of network protection boundaries. No public proof-of-concept exploit was identified at the time of analysis.

AnalysisAIv2 – Oct 13, 2026

Server-side request forgery in Dell Secure Connect Gateway (SCG) Policy Manager allows a remote attacker who already holds high-privilege (administrative) credentials to coerce the appliance into issuing requests to attacker-chosen destinations, causing information disclosure, unauthorized access, and bypass of protection mechanisms (CWE-918; CVE-2026-78024). The scope-change metric (S:C) indicates forged requests can affect systems beyond the vulnerable component, and the assessed vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:L/A:N confirms the exploitation prerequisite is authenticated administrator access - this is the primary limiting factor and means unauthenticated or low-privileged remote users cannot trigger it. At time of analysis there is no public exploit identified and no confirmed active exploitation (CISA KEV: no; SSVC exploitation: none), EPSS is only 0.20% (9th percentile), and a vendor patch is available, so this ranks as a moderate, non-urgent priority despite its 8.7 'High' base score.

v1 Oct 09, 2026 - 10:01 CVSS 7.7

Server-side request forgery in Dell Secure Connect Gateway (SCG) Policy Manager versions prior to 5.34.00.16 allows a remote attacker who already holds high-privilege (administrative/operator) access to the management interface to make the appliance issue requests to arbitrary destinations, enabling information disclosure, bypass of protection mechanisms, and unauthorized access to resources beyond the product's intended security scope. The vulnerability is not reachable by anonymous or low-privileged users and carries a high attack-complexity rating, so it is best characterized as an insider-abuse or post-compromise lateral-movement and pivoting primitive rather than an initial-access vector; no public exploit code or confirmed active exploitation was identified at the time of analysis. With a CVSS base score of 7.7 and no CISA KEV listing or EPSS signal supplied, this is a moderate-priority issue that should be scheduled into normal patch cycles and not treated as an emergency.

RemediationAI

Vendor-released patch: Dell publishes a fix for this issue in SCG Policy Manager per DSA-2026-385 (https://www.dell.com/support/kbdoc/en-ca/000503592/dsa-2026-385-security-update-for-dell-secure-connect-gateway-policy-manager-multiple-vulnerabilities); the CVE description names 5.34.00.16 as the fixed version while EUVD lists the remediated baseline as 5.36.00.16, so upgrade to the latest available release - at minimum 5.36.00.16 where supported - and confirm the fixed build against the advisory, since the reported discrepancy means a 5.34.00.16 install may still be exposed. Until the upgrade is applied, compensating controls matter because exploitation requires an already-authenticated administrator: enforce least privilege and tightly restrict who holds Policy Manager admin accounts, enable strong MFA on those accounts, and audit for compromised or shared credentials, accepting that this only removes the insider/compromised-account path and does not fix the underlying SSRF. Network-side, place the appliance on a segmented management VLAN with restrictive egress filtering and block it from reaching internal management planes, hypervisor APIs, and cloud instance-metadata endpoints (169.254.169.254) - the trade-off is that legitimate integrations or update calls may break and need allow-listing by destination host. Enable outbound-request logging on the appliance and monitor for requests to unusual internal hosts or unexpected external destinations, which introduces log volume and tuning overhead but is the most reliable way to detect exploitation attempts in the absence of a more granular restriction on URL-fetching functionality. Note that no public exploit code has been identified for this CVE and EPSS is low (0.20%), so patching can proceed on a normal change cycle rather than an emergency basis, prioritizing externally reachable or multi-tenant Policy Manager deployments first.

Technical ContextAI · show details

The root cause class is CWE-918 (Server-Side Request Forgery), a flaw in which a server-side component accepts a URL, hostname, or similar network locator influenced by the caller and then performs the request on the caller's behalf without adequate validation or allow-listing. In SCG Policy Manager the likely surface is a request-handling feature (for example an integration, update, or proxy-style function) that fetches or connects to a destination the attacker controls, allowing requests to be directed at internal-only services, cloud metadata endpoints, or other hosts that the appliance can reach but the attacker cannot. The CPE entry cpe:2.3:a:dell:secure_connect_gateway_(scg)_policy_manager:*:*:*:*:*:*:*:* identifies the affected platform without version bounds, so version exposure must be confirmed against the vendor advisory rather than from CPE alone. The CVSS 3.1 vector adds the scope-change condition (S:C), meaning a successful forged request crosses a trust boundary and can impact resources outside the vulnerable Policy Manager component itself, which combined with the high confidentiality impact (C:H) explains the information-disclosure and protection-mechanism-bypass tagging. Dell's own scoring rates integrity impact as High (I:H) while the independent assessment applies I:L, reflecting that forged requests primarily leak data and reach protected endpoints rather than corrupting arbitrary state; both agree the confidentiality impact and the network-reachable, no-user-interaction profile are the driving factors.

DescriptionNVD

Dell Secure Connect Gateway (SCG) Policy Manager, versions prior to 5.34.00.16, contains a Server-Side Request Forgery (SSRF) vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Information disclosure, Protection mechanism bypass, Server-side request forgery, and Unauthorized access.

Executive ViewAI

Why It Matters

Dell Secure Connect Gateway (SCG) Policy Manager carries a high-severity server-side request forgery flaw that lets someone already holding administrative credentials on the appliance redirect its outbound requests to destinations of their choosing, potentially exposing data and reaching systems beyond the gateway itself. The practical exposure is limited because an attacker must first obtain privileged administrative access, and no public exploit code or active exploitation has been observed. Leadership should treat this as a scheduled remediation item rather than an emergency, but should track it closely because the appliance sits in a trusted position relative to managed infrastructure.

Attack Technique

Server-Side Request Forgery exploits applications that fetch remote resources based on user-supplied URLs.

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
