CVE-2024-47241: Dell Secure Connect Gateway Auth Bypass

CVE-2024-47241 Overview

CVE-2024-47241 affects Dell Secure Connect Gateway (SCG) 5.0 Appliance - SRS, version 5.24. The vulnerability stems from improper certificate validation [CWE-295] in the appliance. A remote attacker with low privileges can exploit the flaw to intercept or modify data transmitted between the gateway and remote endpoints. Dell disclosed the issue in security advisory DSA-2024-407 alongside other third-party component fixes. The vulnerability impacts confidentiality and integrity of transmitted data but does not directly affect availability.

Critical Impact
Attackers with low-privileged remote access can bypass certificate validation to perform man-in-the-middle attacks, gaining unauthorized access to and modifying data transmitted through the Dell Secure Connect Gateway.

Affected Products

Dell Secure Connect Gateway (SCG) 5.0 Appliance - SRS
Dell Secure Connect Gateway version 5.24.00.14
Dell SCG deployments relying on the affected 5.24 release branch

Technical Details for CVE-2024-47241

Vulnerability Analysis

CVE-2024-47241 is an Improper Certificate Validation weakness [CWE-295] in Dell Secure Connect Gateway 5.0 Appliance - SRS version 5.24. Dell Secure Connect Gateway acts as a communication broker between customer environments and Dell support infrastructure. When the appliance fails to correctly validate TLS certificates presented by remote endpoints, an attacker positioned on the network path can present a fraudulent certificate that the gateway accepts as trusted.

Because SCG relays telemetry, diagnostic data, and remote support sessions, a successful attack exposes sensitive operational data and allows tampering with the traffic in transit. Exploitation requires network reachability and low-privileged access, but no user interaction. The impact is scoped to confidentiality and integrity of the affected communication channel.

Root Cause

The root cause is the appliance's failure to perform complete certificate chain, hostname, or trust anchor validation before establishing TLS sessions. This class of defect commonly arises from disabled hostname verification, acceptance of self-signed certificates, or missing revocation checks. Dell's advisory attributes the flaw to a third-party component packaged within SCG 5.24.

Attack Vector

An attacker with network access and low privileges positions themselves between the gateway and a remote endpoint. The attacker presents a rogue TLS certificate. Because certificate validation is improper, the gateway completes the handshake and establishes a session with the attacker-controlled endpoint. The attacker then reads or modifies the transmitted data before relaying it to the legitimate destination. No verified public proof-of-concept exploit or exploit database entry is available for this CVE.

Detection Methods for CVE-2024-47241

Indicators of Compromise

Unexpected TLS certificate chains or issuer names observed in outbound sessions from the SCG appliance.
Anomalous connections from the SCG appliance to IP addresses outside Dell's published support infrastructure ranges.
Gateway logs showing successful TLS sessions with certificates that fail external validation when replayed.
Discrepancies between telemetry data sent by SCG and what appears in Dell support portals.

Detection Strategies

Inspect outbound TLS sessions from SCG appliances using network-based decryption or certificate transparency monitoring.
Compare presented certificate fingerprints against a known-good baseline of Dell endpoint certificates.
Audit SCG appliance version reporting to identify hosts running vulnerable 5.24.00.14 builds.
Alert on new or unexpected destination IPs contacted by the SCG management interface.

Monitoring Recommendations

Forward SCG appliance logs and network flow records to a centralized analytics platform for correlation.
Enable TLS certificate pinning validation at upstream network devices where feasible.
Track configuration drift on SCG appliances, including changes to trusted CA stores.
Review Dell advisory DSA-2024-407 periodically for updated indicators or fixed version guidance.

How to Mitigate CVE-2024-47241

Immediate Actions Required

Identify all Dell Secure Connect Gateway 5.0 Appliance - SRS instances running version 5.24.00.14 or the 5.24 branch.
Apply the fixed version referenced in Dell advisory DSA-2024-407 as soon as maintenance windows permit.
Restrict network access to and from SCG appliances to only required Dell support endpoints.
Rotate any credentials or sensitive material that may have been transmitted through affected gateways.

Patch Information

Dell has published fixed builds and remediation guidance in Dell Security Update DSA-2024-407. Administrators should follow the Dell knowledge base article to obtain the corrected SCG release and apply it according to Dell's upgrade procedure for the SCG 5.0 Appliance - SRS.

Workarounds

Place SCG appliances behind a TLS-inspecting egress proxy that enforces strict certificate validation until the patch is applied.
Limit outbound connectivity from SCG to Dell-documented destination hosts using firewall allowlists.
Restrict administrative and low-privileged access to SCG management interfaces to trusted networks only.
Monitor SCG connections continuously for anomalous certificates until upgrading to the fixed release.

bash

# Configuration example: restrict SCG egress to Dell support endpoints
# Replace <SCG_IP> with the appliance address and adjust destination list per Dell documentation
iptables -A OUTPUT -s <SCG_IP> -p tcp --dport 443 -d <dell_support_cidr> -j ACCEPT
iptables -A OUTPUT -s <SCG_IP> -p tcp --dport 443 -j DROP
