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.

Executive Summary

This vulnerability in Apache OpenOffice allows an attacker to create a document with external links that load without user permission. Specifically, documents using a certain URI scheme can load external files automatically, potentially transmitting system information like environment variables or configuration settings without prompting the user.

Impact Analysis

The vulnerability can lead to unauthorized disclosure of sensitive system information by automatically loading external links embedded in documents. This could expose environment variables or configuration data to attackers without user consent, potentially compromising system security and privacy.

Mitigation Strategies

Upgrade Apache OpenOffice to version 4.1.16 or later, as this version fixes the missing Authorization vulnerability that allows external links to be loaded without user prompt.
