CVE-2019-3707: WS-MAN Authentication Bypass Vulnerability

Dell EMC iDRAC9 versions prior to 3.30.30.30 contain an authentication bypass vulnerability. A remote attacker may potentially exploit this vulnerability to bypass authentication and gain access to the system by sending specially crafted input data to the WS-MAN interface.

Security readout for executives and security teams

Plain-English summary

This vulnerability affects Dell EMC iDRAC9 management controllers before version 3.30.30.30. If the WS-MAN management interface is reachable, an unauthenticated remote attacker could bypass login controls and access the system. The highest business concern is disruption of server management availability, with some confidentiality and integrity exposure.

Executive priority

Treat this as high priority for infrastructure teams because iDRAC manages physical servers. Exposed management interfaces can create outsized operational risk even when data impact is limited.

Technical view

CVE-2019-3707 is an iDRAC9 WS-MAN authentication bypass. The CVSS 3.0 score is 8.6 with network attack vector, low complexity, no privileges, and no user interaction. The published vector indicates limited confidentiality and integrity impact, and high availability impact.

Likely exposure

Organizations are most exposed where Dell EMC iDRAC9 management interfaces are reachable over a network, especially if WS-MAN is enabled and firmware is older than 3.30.30.30.

Exploitation context

The CVE record says exploitation may be possible through specially crafted input to WS-MAN. The provided sources do not show CISA KEV listing or active exploitation evidence, so active exploitation should not be assumed.

Researcher notes

The source bundle does not provide exploit proof, detailed affected platform matrix, or workaround specifics beyond the version boundary and Dell advisory reference. Avoid broadening scope beyond Dell EMC iDRAC9 and WS-MAN.

Mitigation direction

  • Identify Dell EMC iDRAC9 assets and their firmware versions.
  • Prioritize systems running firmware older than 3.30.30.30.
  • Follow Dell advisory guidance for remediation and firmware updates.
  • Restrict network access to iDRAC management interfaces.
  • Limit WS-MAN exposure to trusted management networks only.

Validation and detection

  • Inventory iDRAC9 firmware versions across server fleets.
  • Confirm whether WS-MAN is enabled and network-reachable.
  • Verify affected systems are no longer below version 3.30.30.30.
  • Review management access logs for unexplained authentication or availability events.
  • Confirm segmentation prevents untrusted access to iDRAC interfaces.
