Security readout for executives and security teams
Plain-English summary
CVE-2021-0194 is an access-control weakness in Intel(R) In-Band Manageability software before 2.13.0. A user who already has high privileges may use network access to escalate further and potentially compromise confidentiality, integrity, and availability. This matters most in environments that deploy this manageability software on reachable operations networks.
Executive priority
Treat as a high-priority remediation item where the software is present, especially on management networks. The requirement for existing high privileges lowers broad internet-scale risk, but successful misuse could have full system impact.
Technical view
The CVE describes improper access control in Intel(R) In-Band Manageability software before version 2.13.0. CVSS 3.1 is 7.2: network vector, low complexity, high privileges required, no user interaction, unchanged scope, and high confidentiality, integrity, and availability impact. No CWE is listed in the provided sources.
Likely exposure
Exposure is limited to systems running Intel(R) In-Band Manageability software earlier than 2.13.0. The provided sources do not identify specific platforms, operating systems, or deployment models, so teams should confirm installation and version through asset inventory.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability requires an already privileged user and network access, reducing opportunistic risk but increasing concern for insider threats, compromised admin accounts, or poorly segmented management networks.
Researcher notes
The available public details are sparse: affected product and version boundary are clear, but exploit mechanics, CWE mapping, and deployment-specific exposure are not provided. Validation should focus on version discovery, reachable management surfaces, and privileged-user access paths.
Mitigation direction
- Upgrade Intel(R) In-Band Manageability software to version 2.13.0 or later.
- Review Intel advisory INTEL-SA-00549 for vendor-specific remediation guidance.
- Restrict network access to manageability services to trusted administration networks.
- Review privileged account access for systems running the affected software.
Validation and detection
- Inventory systems for Intel(R) In-Band Manageability software installations.
- Verify installed versions are 2.13.0 or later.
- Confirm management interfaces are not broadly network-reachable.
- Check privileged account activity on affected management systems.
