CVE-2020-13958: A vulnerability in Apache OpenOffice scripting events allows an attacker to construct documents containing...

A vulnerability in Apache OpenOffice scripting events allows an attacker to construct documents containing hyperlinks pointing to an executable on the target users file system. These hyperlinks can be triggered unconditionally. In fixed versions no internal protocol may be called from the document event handler and other hyperlinks require a control-click.

Security readout for executives and security teams

Plain-English summary

Malicious OpenOffice documents could abuse scripting events to launch hyperlinks to executables already on a user’s filesystem. This is a user-workstation risk tied to opening untrusted documents. The bundle does not provide a CVSS score or evidence of active exploitation.

Executive priority

Treat as a targeted workstation hardening issue. Prioritize teams that receive external documents, but do not escalate as emergency without evidence of active exploitation or broader exposure.

Technical view

Apache OpenOffice 4.0 through 4.1.7 allowed document event handlers to trigger internal protocol hyperlinks unconditionally, including links to local executables. Fixed behavior blocks internal protocol calls from document event handlers and requires control-click for other hyperlinks.

Likely exposure

Exposure is likely limited to endpoints where Apache OpenOffice 4.0 through 4.1.7 is installed and users open untrusted documents. Server exposure is not indicated by the supplied sources.

Exploitation context

The supplied sources do not show KEV listing or active exploitation. Abuse appears to require a crafted document and a referenced executable path on the target user’s filesystem.

Researcher notes

Key missing data includes CVSS, CWE mapping, exploit telemetry, and the exact fixed release in the provided bundle. Analysis should stay scoped to Apache OpenOffice, document event handlers, internal protocol hyperlinks, and affected versions 4.0 to 4.1.7.

Mitigation direction

  • Inventory endpoints for Apache OpenOffice 4.0 through 4.1.7.
  • Move affected installations to a fixed Apache OpenOffice version per Apache guidance.
  • Restrict opening untrusted OpenOffice documents until remediation is complete.
  • Use email and web filtering to reduce delivery of suspicious office documents.

Validation and detection

  • Confirm installed Apache OpenOffice versions across managed endpoints.
  • Check whether affected users handle externally supplied OpenOffice documents.
  • Verify upgraded clients no longer fall within versions 4.0 through 4.1.7.
  • Review endpoint detections for suspicious document-triggered process launches.
