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 · unedited
Buffer overflow in the SMB_Connect_Server function in FreeRadius 1.1.3 and earlier allows attackers to execute arbitrary code related to the server desthost field of an SMB_Handle_Type instance. NOTE: the impact of this issue has been disputed by a reliable third party and the vendor, who states that exploitation is limited "only to local administrators who have write access to the server configuration files." CVE concurs with the dispute

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 · high confidence

Buffer overflow in FreeRadius 1.1.3 and earlier in the SMB_Connect_Server function allows arbitrary code execution via the desthost field of an SMB_Handle_Type instance. However, the CVE itself notes this is disputed - exploitation requires local administrator privileges with write access to server configuration files, significantly limiting practical impact.

MitigationUpgrade FreeRadius beyond version 1.1.3; restrict administrative access to configuration files to trusted local administrators only.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify FreeRadius version
    Run 'radiusd -v' or check package manager (dpkg -l freeradius, rpm -q freeradius) to determine installed version
    Affected if Version is 1.1.3 or earlier
  2. Locate SMB module configuration
    Search for 'smb' or 'SMB' in the FreeRadius configuration directory (typically /etc/raddb/) and check if rlm_smb or similar SMB-related module is loaded in radiusd.conf
    Affected if SMB module is enabled and configured with a desthost parameter
  3. Inspect SMB desthost parameter
    Examine the SMB module configuration in radiusd.conf or modules/smb for the desthost field setting
    Affected if A desthost value is defined in the SMB module configuration and the server runs with elevated privileges
  4. Verify configuration file permissions
    Check ownership and permissions on FreeRadius configuration files (ls -la /etc/raddb/)
    Affected if Non-admin users have write access to configuration files that the SMB module reads

The server is affected if running FreeRadius version 1.1.3 or earlier with the SMB module enabled and the desthost parameter configured, especially if configuration files are writable by non-administrative users.

From vendor data
Upgrade available Upgrade to a release after 1.1.3
Interim mitigation

Upgrade FreeRadius beyond version 1.1.3; restrict administrative access to configuration files to trusted local administrators only.
