CVE-2025-23382: Dell SCG Information Disclosure Flaw

CVE-2025-23382 Overview

CVE-2025-23382 affects Dell Secure Connect Gateway (SCG) 5.0 Appliance - SRS, version 5.26. The vulnerability is classified as Exposure of Sensitive System Information to an Unauthorized Control Sphere [CWE-497]. An authenticated attacker with high privileges and remote access can retrieve sensitive system information from the appliance. Successful exploitation requires user interaction and results in a scope change, allowing disclosed data to affect components beyond the vulnerable appliance itself.

Critical Impact
An authenticated remote attacker can extract sensitive system information from the Dell SCG appliance, exposing data that may aid further attacks against connected infrastructure.

Affected Products

Dell Secure Connect Gateway (SCG) 5.0 Appliance - SRS, version 5.26.00.20 (virtual)
Deployments using the Dell SRS remote support integration
Environments running unpatched SCG 5.0 versions prior to the fixed release

Technical Details for CVE-2025-23382

Vulnerability Analysis

Dell Secure Connect Gateway is a support technology that enables secure, bi-directional communication between Dell infrastructure and Dell support systems. The flaw resides in how the SCG 5.0 appliance handles sensitive system data, allowing an authorized user to observe information that should remain isolated from their control sphere.

Exploitation requires an attacker who already holds high privileges on the appliance and who can induce a legitimate user to perform an action. Because the vulnerability triggers a scope change, disclosed information can influence security-relevant decisions in components beyond the appliance boundary. The confidentiality impact is high, while integrity and availability are unaffected.

Root Cause

The root cause maps to [CWE-497]: Exposure of Sensitive System Information to an Unauthorized Control Sphere. The appliance exposes system-level information through an interface accessible to authenticated users without sufficient control over which principals may read that data. Dell attributes the issue to third-party components bundled within the SCG appliance, as noted in the Dell Security Update Advisory.

Attack Vector

The attack vector is network-based but constrained by high attack complexity, low-privilege authentication requirements, and mandatory user interaction. An attacker with valid credentials on the SCG appliance interacts with the vulnerable interface and coerces a user action that returns sensitive system data. The disclosed data can include configuration, credential material, or internal state useful for pivoting to managed Dell infrastructure. No verified public proof-of-concept exploit is available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

See the Dell Security Update Advisory for vendor-specific technical details.

Detection Methods for CVE-2025-23382

Indicators of Compromise

Unexpected authenticated sessions on the SCG appliance from unusual source addresses or during off-hours
Anomalous read access to configuration, diagnostic, or system-information endpoints on the SCG management interface
Outbound transfers of appliance diagnostic bundles to destinations outside the Dell support telemetry path

Detection Strategies

Audit SCG appliance access logs for privileged accounts performing repeated queries against system-information endpoints
Correlate SCG authentication events with downstream reconnaissance activity targeting Dell infrastructure managed by the gateway
Alert on privileged account activity that occurs outside documented administrative maintenance windows

Monitoring Recommendations

Forward SCG appliance syslog and audit trails to a centralized SIEM for long-term retention and correlation
Baseline normal administrative behavior on the SCG appliance and alert on deviations in query volume or endpoint access
Monitor privileged credential usage and rotate credentials that have interactive access to the SCG management plane

How to Mitigate CVE-2025-23382

Immediate Actions Required

Apply the fixed SCG release referenced in the Dell Security Update Advisory
Inventory all Dell SCG 5.0 appliances running version 5.26.00.20 and prioritize them for patching
Restrict administrative access to the SCG management interface to a dedicated management network segment
Rotate credentials for privileged SCG accounts and enforce multi-factor authentication where supported

Patch Information

Dell has published fixed versions and remediation guidance in Dell KB 000291028. Administrators should upgrade to the version identified in that advisory. The advisory covers this and related third-party component vulnerabilities affecting the SCG appliance.

Workarounds

Limit inbound network access to the SCG management interface using firewall rules or an internal jump host
Reduce the number of accounts holding high privileges on the appliance and review role assignments regularly
Disable or restrict features that expose diagnostic or system-information endpoints when they are not required for operations

bash

# Example: restrict access to the SCG management interface with iptables
# Replace 10.0.0.0/24 with your dedicated management subnet
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
