CVE-2025-38739 Overview
CVE-2025-38739 affects Dell Digital Delivery versions prior to 5.6.1.0. The software contains an Insufficiently Protected Credentials weakness [CWE-522]. A remote unauthenticated attacker can potentially exploit this flaw to obtain sensitive information.
Dell Digital Delivery is preinstalled on Dell consumer and commercial systems to download and install software purchased with the device. The exposure of credentials in this component creates an information disclosure risk without requiring authentication or user interaction. Dell has published Security Advisory DSA-2025-302 to address the issue.
Critical Impact
A network-based attacker can retrieve inadequately protected credentials from Dell Digital Delivery without authentication, resulting in confidentiality loss and enabling downstream credential abuse.
Affected Products
- Dell Digital Delivery versions prior to 5.6.1.0
- Dell consumer and commercial systems shipping with Digital Delivery preinstalled
- Endpoints where users manually installed vulnerable versions of Dell Digital Delivery
Discovery Timeline
- 2025-08-04 - CVE-2025-38739 published to the National Vulnerability Database

Technical Details for CVE-2025-38739
Vulnerability Analysis
CVE-2025-38739 is an Insufficiently Protected Credentials vulnerability [CWE-522] in Dell Digital Delivery. The component handles credentials in a manner that does not provide adequate confidentiality protection against a remote attacker. Because the attack vector is Network and no authentication or user interaction is required, an attacker with reachability to the vulnerable service or its exposed interface can trigger information disclosure.
The impact scope is limited to confidentiality. Integrity and availability of the host are not directly affected by this issue. However, disclosed credentials can be reused against Dell backend services or other systems where the same credentials grant access, extending the practical impact beyond the initial disclosure.
Root Cause
The root cause is inadequate protection of credential material managed by Dell Digital Delivery. Under [CWE-522], the product either transmits or stores authentication credentials using a method susceptible to unauthorized interception or retrieval. Dell's advisory DSA-2025-302 addresses the flaw in version 5.6.1.0 and later.
Attack Vector
Exploitation requires network access to the exposed component. The attacker does not need valid credentials, elevated privileges, or user interaction. Successful exploitation yields credential material that the attacker can then use against dependent services. Public proof-of-concept code is not available at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
See the Dell Security Advisory DSA-2025-302 for vendor-provided technical details.
Detection Methods for CVE-2025-38739
Indicators of Compromise
- Presence of Dell Digital Delivery binaries with version metadata below 5.6.1.0 on managed endpoints
- Unexpected outbound connections from the DellDigitalDelivery.exe process to non-Dell destinations
- Authentication anomalies on Dell-associated accounts shortly after network exposure of vulnerable hosts
Detection Strategies
- Inventory installed software across the fleet and flag any Dell Digital Delivery installation with a version earlier than 5.6.1.0
- Monitor process-level network telemetry for the Dell Digital Delivery service and alert on non-standard destinations or protocols
- Correlate endpoint software inventory with identity provider logs to identify potential credential reuse following a suspected disclosure
Monitoring Recommendations
- Enable continuous vulnerability assessment on all Dell endpoints and integrate results into the SIEM for tracking remediation status
- Alert on new installations or downgrades of Dell Digital Delivery to versions below 5.6.1.0
- Review authentication logs for Dell service accounts and rotate any credentials suspected of exposure
How to Mitigate CVE-2025-38739
Immediate Actions Required
- Upgrade Dell Digital Delivery to version 5.6.1.0 or later on all affected endpoints per Dell Security Advisory DSA-2025-302
- Identify systems with the vulnerable version through software inventory tooling and prioritize internet-exposed or mobile endpoints
- Rotate any credentials associated with Dell Digital Delivery workflows if compromise is suspected
Patch Information
Dell has released a fixed version of Dell Digital Delivery, 5.6.1.0, that resolves the Insufficiently Protected Credentials condition. Administrators should reference Dell Security Advisory DSA-2025-302 for the authoritative remediation guidance, download locations, and impacted SKU list.
Workarounds
- Uninstall Dell Digital Delivery on systems where it is not required until patching can be completed
- Restrict outbound and inbound network access for hosts running vulnerable versions using host-based firewall rules
- Disable the Dell Digital Delivery service on endpoints that do not need to receive purchased software installations
