Security readout for executives and security teams
Plain-English summary
CVE-2021-0193 is an improper authentication flaw in Intel In-Band Manageability software before version 2.13.0. A user who already has high privileges could use network access to gain further control. The main business risk is compromise of confidentiality, integrity, and availability on systems where this management software is deployed.
Executive priority
Prioritize remediation where this software manages sensitive systems or is reachable across networks. The flaw requires existing high privileges, which reduces broad attack likelihood, but successful misuse could have full confidentiality, integrity, and availability impact.
Technical view
The CVE maps to CWE-287 and has CVSS 3.1 score 7.2: AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. The issue affects Intel In-Band Manageability software before 2.13.0 and may allow escalation of privilege over the network by a privileged user.
Likely exposure
Exposure is limited to environments running Intel In-Band Manageability software before version 2.13.0. Risk is higher where the software is reachable over management networks and where privileged user accounts exist on affected systems.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. Exploitation is described as network-accessible, low complexity, no user interaction, but requiring high privileges before escalation is possible.
Researcher notes
Evidence is limited to the CVE description, CVSS vector, affected version boundary, CWE-287 classification, and Intel advisory reference. No exploit details, indicators, or independent active exploitation claims are present in the provided bundle.
Mitigation direction
- Inventory Intel In-Band Manageability deployments and record installed versions.
- Upgrade affected installations to version 2.13.0 or later where applicable.
- Review Intel advisory INTEL-SA-00549 for environment-specific guidance.
- Restrict management network access to trusted administrative paths.
- Review privileged account access on systems using this software.
Validation and detection
- Confirm no deployed Intel In-Band Manageability instance is older than 2.13.0.
- Check whether affected services are reachable from untrusted networks.
- Verify privileged account membership and recent changes on managed systems.
- Review management logs for unexpected privileged actions or configuration changes.
- Track the CVE and Intel advisory for revised guidance.
