CVE-2024-32038
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 · uneditedWazuh is a free and open source platform used for threat prevention, detection, and response. There is a buffer overflow hazard in wazuh-analysisd when handling Unicode characters from Windows Eventchannel messages. It impacts Wazuh Manager 3.8.0 and above. This vulnerability is fixed in Wazuh Manager 4.7.2.
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 confidenceA buffer overflow vulnerability exists in the wazuh-analysisd component when processing Unicode characters from Windows Eventchannel messages. This memory safety flaw could allow an attacker to corrupt memory by sending specially crafted Unicode data, potentially leading to remote code execution or denial of service.

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.
-
Check installed Wazuh versionRun 'wazuh-control info' or check '/var/ossec/etc/ossec.conf' for the version field, or use 'rpm -qa | grep wazuh-manager' / 'dpkg -l | grep wazuh'Affected if Version is greater than or equal to 3.8.0 and less than 4.7.2
-
Verify wazuh-analysisd component is presentCheck if the analysisd daemon exists by running 'ps - aux | grep analysisd' or checking for the binary at '/var/ossec/bin/wazuh-analysisd'Affected if The analysisd component is running or installed
-
Confirm Windows Eventchannel log collection is enabledInspect the Wazuh agent configuration or the central configuration on the manager for <logall> or Windows Eventchannel <localfile> entries. Check ossec.conf for <field name="eventchannel"> sectionsAffected if Windows Eventchannel input is configured and actively receiving logs from Windows agents
You are affected if your Wazuh version is between 3.8.0 and 4.7.2 (exclusive) AND you have Windows Eventchannel logging enabled that feeds into the wazuh-analysisd component.

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.
dbcve · scoped4.7.2
Upgrade Wazuh Manager to version 4.7.2 or later to remediate this vulnerability. If immediate upgrade is not possible, consider restricting or monitoring Windows Eventchannel message inputs until the patch can be applied.
Wazuh Manager 4.7.2
- 1. Back up your current Wazuh Manager configuration and data.
- 2. Upgrade Wazuh Manager to version 4.7.2 or later.
- 3. Verify the upgrade was successful by checking the Wazuh Manager version.
- 4. Restart the wazuh-manager service to ensure all components are running with the patched version.
- 5. Test that Windows Eventchannel log processing is functioning correctly with Unicode characters.
