Security readout for executives and security teams
Plain-English summary
Dell EMC Integrated Data Protection Appliance before version 2.3 has a stored cross-site scripting issue. A malicious ACM admin could save hostile HTML or JavaScript in a Cloud DR add-on field, causing another user's browser to run it inside the appliance application.
Executive priority
Treat this as high priority for affected backup and recovery infrastructure. It requires privileged access, but successful abuse could compromise browser sessions and administrative trust boundaries inside a critical data protection platform.
Technical view
CVE-2019-3747 is CWE-79 stored XSS in Dell EMC Integrated Data Protection Appliance prior to 2.3. CVSS 3.0 is 8.4 with network access, low complexity, high privileges required, user interaction required, changed scope, and high confidentiality, integrity, and availability impacts.
Likely exposure
Exposure is limited to organizations running Dell EMC Integrated Data Protection Appliance versions before 2.3. The attacker must be a remote ACM admin, and a victim must access the affected page. Risk is highest where ACM admin access is broadly assigned or insufficiently monitored.
Exploitation context
The provided sources do not show active exploitation, and this CVE is not marked as CISA KEV. The described scenario is insider or compromised-admin abuse: an ACM admin stores script content that later executes when another user views the vulnerable Cloud DR page.
Researcher notes
Evidence supports affected product, version boundary, vulnerability class, and privilege/user-interaction requirements. The source bundle does not provide exploit details, active exploitation evidence, or detailed mitigation steps beyond the version boundary and Dell advisory reference.
Mitigation direction
- Confirm Dell EMC IDPA version and identify systems prior to 2.3.
- Review Dell advisory DSA-2019-112 for the vendor-supported fixed version and instructions.
- Upgrade affected appliances to version 2.3 or later if supported by Dell guidance.
- Restrict ACM admin access to trusted users only.
- Audit ACM admin accounts for unnecessary or stale privileges.
Validation and detection
- Inventory Dell EMC IDPA appliances and record current versions.
- Confirm whether Cloud DR add-on functionality is present or enabled.
- Review ACM admin user lists for unexpected or excessive access.
- Check change and audit logs for suspicious Cloud DR field modifications.
- Verify remediation against Dell advisory DSA-2019-112.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
