CVE-2024-24582
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper input validation in XmlCli feature for UEFI firmware for some Intel(R) processors may allow privileged user to potentially enable escalation of privilege via local access.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA vulnerability in the XmlCli feature of UEFI firmware for certain Intel processors allows improper input validation that could be exploited by a privileged local user to escalate their privileges. XmlCli appears to be a command-line interface for XML-based configuration in the UEFI environment.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the Intel processor modelUse system information tools such as 'dmidecode -processor', 'lscpu', CPU-Z (Windows), or the System Information utility to determine the exact Intel processor model number.Affected if The system uses an Intel processor that includes the XmlCli feature in its UEFI firmware (specific processor families vary by Intel platform).
-
Check if XmlCli is enabled in UEFI/BIOSAccess the system UEFI/BIOS setup (typically by pressing Del, F2, or F12 during boot). Navigate to advanced configuration menus and look for settings named 'XmlCli', 'XML CLI', 'Xml Command Line Interface', or similar. Record whether the feature is present and if it is enabled or disabled.Affected if The XmlCli feature is present and enabled in the UEFI settings. If it is disabled or not present, the vulnerability cannot be exploited.
-
Determine the installed UEFI firmware versionRetrieve the UEFI/BIOS version from the system. On Linux, use 'dmidecode -s bios-version' or check /sys/class/dmi/id/. On Windows, run 'wmic bios get smbiosbiosversion' or check in System Information. Compare this version number against the Intel advisory for CVE-2024-24582 to identify if a patch has been applied.Affected if The installed UEFI firmware version is older than the corrected version released by Intel for the specific processor model.
-
Verify local user privilegesReview local user accounts and their privilege levels on the system using 'whoami /all' (Windows) or 'id' and 'cat /etc/passwd' (Linux). Identify accounts with administrative or elevated privileges.Affected if The system has multiple local privileged accounts or weak access controls, allowing a local user with existing elevated privileges to potentially exploit the XmlCli flaw for further escalation.
The system is affected if it runs an Intel processor with XmlCli in its UEFI, the XmlCli feature is enabled, and the installed UEFI firmware version has not been updated to the Intel-patched version for this CVE.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Intel firmware update (BIOS/UEFI update) for affected processors as provided by Intel. Restrict physical local access to systems and ensure only trusted privileged users have access.
