An information disclosure vulnerability occurs when LibreOffice 6.0.3 and Apache OpenOffice Writer 4.1.5 automatically process and initiate an SMB connection embedded in a malicious file, as demonstrated by xlink:href=file://192.168.0.2/test.jpg within an office:document-content element in a .odt XML document.

Security readout for executives and security teams

Plain-English summary

A malicious .odt document can make LibreOffice 6.0.3 or Apache OpenOffice Writer 4.1.5 automatically contact an attacker-controlled SMB path. That can expose information through the outbound connection. Treat this mainly as a document-handling and credential-exposure risk, not a system takeover vulnerability based on the supplied sources.

Executive priority

Prioritize remediation where users routinely open external documents or where workstations can reach SMB destinations. The business risk is credential or network information exposure from malicious documents, with public exploit material but no confirmed active exploitation in the supplied sources.

Technical view

The CVE describes automatic processing of an ODT XML xlink:href file URI that initiates an SMB connection. The demonstrated affected applications are LibreOffice 6.0.3 and Apache OpenOffice Writer 4.1.5. Severity and CVSS are not provided in the source bundle. Vendor advisories exist, but the bundle does not detail specific fixed versions.

Likely exposure

Exposure is most likely on endpoints or document-processing systems that open untrusted ODT files with the named LibreOffice or OpenOffice Writer versions. Network egress to SMB destinations increases practical risk.

Exploitation context

The bundle includes an Exploit-DB reference, so public exploit information exists. CISA KEV is false in the supplied data, and no cited source in the bundle confirms active exploitation in the wild.

Researcher notes

Evidence is limited to the CVE description, distro advisories, Apache mailing-list references, and public exploit reference. The source bundle does not provide CVSS, CWE, exact fixed versions, or confirmed exploitation. Avoid broader affected-version claims unless verified against vendor advisories.

Mitigation direction

  • Update LibreOffice and OpenOffice using vendor guidance from Debian, Red Hat, Ubuntu, and Apache sources.
  • Block or monitor outbound SMB from workstations where business requirements allow.
  • Treat unexpected ODT files as untrusted, especially from email or external collaboration channels.
  • Review document-processing services for use of affected office software versions.

Validation and detection

  • Inventory LibreOffice and Apache OpenOffice Writer versions across endpoints and processing servers.
  • Check whether LibreOffice 6.0.3 or OpenOffice Writer 4.1.5 are present.
  • Review proxy, firewall, or EDR telemetry for unexpected SMB connections after opening documents.
  • Confirm vendor advisory status before declaring patched or not affected.
