Security readout for executives and security teams
Plain-English summary
CVE-2019-3764 affects Dell EMC iDRAC management controllers. A low-privileged authenticated iDRAC user could potentially bypass authorization controls and access sensitive information, including password hashes. This matters because iDRAC manages servers out-of-band and should be tightly controlled.
Executive priority
Treat this as a moderate-priority infrastructure management issue. It is not documented as actively exploited in the provided sources, but affected iDRAC systems can expose sensitive credential material if compromised by an authenticated low-privileged user.
Technical view
Dell reports improper authorization in iDRAC7 before 2.65.65.65, iDRAC8 before 2.70.70.70, and iDRAC9 before 3.36.36.36. CVSS 3.0 is 5.0 with network access, high complexity, low privileges, no user interaction, and limited confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely where Dell servers run affected iDRAC7, iDRAC8, or iDRAC9 firmware and allow low-privileged iDRAC logins. Risk is higher if iDRAC interfaces are reachable beyond trusted management networks.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires an authenticated low-privileged iDRAC user and is rated high complexity, but could disclose sensitive information such as password hashes.
Researcher notes
The vulnerability is CWE-285 improper authorization. The CVSS vector is AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L. Public details are limited; do not assume unauthenticated access, specific exploit paths, or broader product impact beyond the cited iDRAC versions.
Mitigation direction
- Upgrade iDRAC7 to 2.65.65.65 or later.
- Upgrade iDRAC8 to 2.70.70.70 or later.
- Upgrade iDRAC9 to 3.36.36.36 or later.
- Review Dell advisory guidance before maintenance windows.
- Restrict iDRAC access to trusted management networks.
- Limit and review low-privileged iDRAC accounts.
Validation and detection
- Inventory Dell iDRAC7, iDRAC8, and iDRAC9 assets.
- Verify installed iDRAC firmware versions against affected thresholds.
- Confirm iDRAC interfaces are not exposed to untrusted networks.
- Review iDRAC user accounts for unnecessary low-privilege access.
- Check vendor advisory status for any superseding guidance.
