CVE-2025-64407: Apache OpenOffice: URL fetching can be used to exfiltrate arbitrary INI file values and environment variables

[Arrigo Marchiori <ardovm () apache org>]

Severity: Moderate 

Affected versions:

- Apache OpenOffice through 4.1.15

Description:

Apache OpenOffice documents can contain links. A missing Authorization vulnerability in Apache OpenOffice allowed an 
attacker to craft a document that would cause external links 
to be loaded without prompt. Such links could also be used to transmit system information, such as environment 
variables or configuration settings.

In the affected versions of Apache OpenOffice, documents that used a certain URI scheme linking to external files would 
load the contents of such files without prompting the user for 
permission to do so. Such URI scheme allows to include system configuration data, that is not supposed to be 
transmitted externally.

This issue affects Apache OpenOffice: through 4.1.15.

Users are recommended to upgrade to version 4.1.16, which fixes the issue.





The LibreOffice suite reported this issue as CVE-2024-12426.
