CVE-2026-76114: Dell SCG Policy Manager Information Disclosure

CVE-2026-76114 Overview

CVE-2026-76114 affects Dell Secure Connect Gateway (SCG) Policy Manager in all versions prior to 5.34.00.16. The flaw is a Cleartext Transmission of Sensitive Information weakness [CWE-319]. An unauthenticated remote attacker positioned to observe network traffic can intercept sensitive data transmitted by the Policy Manager. Successful exploitation leads to information disclosure without requiring credentials or user interaction. Dell has published advisory DSA-2026-385 and released a fixed build to remediate the issue.

Critical Impact
Sensitive data handled by Dell SCG Policy Manager can be intercepted in transit by an unauthenticated network attacker, resulting in confidentiality loss.

Technical Details for CVE-2026-76114

Vulnerability Analysis

The vulnerability resides in how Dell SCG Policy Manager transmits sensitive information across the network. The application sends data without adequate cryptographic protection, exposing it to any attacker with network visibility between client and server. Because the transport channel does not enforce confidentiality guarantees, an adversary can passively capture protocol traffic and extract sensitive fields. The attack requires no authentication and no user interaction, but the CVSS vector indicates high attack complexity, meaning specific network conditions must be met to succeed. Impact is limited to confidentiality; integrity and availability are not affected.

Root Cause

The root cause is improper protection of data in transit, classified under [CWE-319] Cleartext Transmission of Sensitive Information. Sensitive Policy Manager data is placed on the wire without enforced encryption or with cryptographic controls that fail to protect the payload. This design flaw exposes the affected data to network observers regardless of endpoint security.

Attack Vector

The attack vector is network-based. An attacker in a position to observe or intercept traffic between the Policy Manager and communicating components can capture the cleartext data. Typical attacker positions include compromised network devices, adjacent hosts on shared network segments, and monitoring points along the routing path. No credentials or user actions are required to trigger disclosure.

No public proof-of-concept code has been released for CVE-2026-76114. Refer to the Dell Security Advisory DSA-2026-385 for authoritative technical details.

Detection Methods for CVE-2026-76114

Indicators of Compromise

Unencrypted or weakly encrypted sessions originating from or destined to Dell SCG Policy Manager hosts.
Unexpected packet captures, port mirroring, or SPAN configurations on switches carrying SCG Policy Manager traffic.
Anomalous outbound connections from network segments hosting the Policy Manager to untrusted destinations.

Detection Strategies

Inspect network flows around Policy Manager systems for plaintext protocol usage where TLS is expected.
Audit SCG Policy Manager version banners and management interfaces to identify hosts running builds prior to 5.34.00.16.
Correlate authentication and configuration events on Policy Manager with adjacent network monitoring alerts to identify potential interception attempts.

Monitoring Recommendations

Enable full packet capture on segments carrying Dell SCG management traffic and retain metadata for retrospective analysis.
Alert on ARP spoofing, rogue DHCP, and unauthorized promiscuous-mode interfaces near Policy Manager hosts.
Track configuration drift and unpatched Policy Manager instances through a vulnerability management workflow.

How to Mitigate CVE-2026-76114

Immediate Actions Required

Upgrade Dell Secure Connect Gateway Policy Manager to version 5.34.00.16 or later without delay.
Restrict network access to the Policy Manager to trusted management subnets using firewall rules and network segmentation.
Review recent network captures and logs for evidence of interception on segments carrying Policy Manager traffic.

Patch Information

Dell has released a fixed build in version 5.34.00.16 of Secure Connect Gateway Policy Manager. Full remediation details are documented in the Dell Security Advisory DSA-2026-385. Apply the vendor-supplied update following Dell's documented upgrade procedure.

Workarounds

Isolate the Policy Manager on a dedicated management VLAN accessible only to authorized administrators.
Enforce encrypted transport at the network layer, such as IPsec tunnels, between Policy Manager and its clients until patching completes.
Disable or block unused network services on the Policy Manager host to reduce exposure.

bash

# Configuration example: restrict inbound access to SCG Policy Manager
# Replace 10.0.0.0/24 with your authorized 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
