CVE-2023-47804: Apache OpenOffice: Macro URL arbitrary script execution

2023-12-28 Thread Arrigo Marchiori
Severity: important

Affected versions:

- Apache OpenOffice through 4.1.15

Description:

Apache OpenOffice documents can contain links that call internal macros with 
arbitrary arguments. Several URI Schemes are defined for this purpose.

Links can be activated by clicks, or by automatic document events.

The execution of such links must be subject to user approval.

In the affected versions of OpenOffice, approval for certain links is not 
requested; when activated, such links could therefore result in arbitrary 
script execution.

This is a corner case of CVE-2022-47502.
