What is CVE-2023-47804?
CVE-2023-47804 is a high-severity code injection vulnerability in Apache Openoffice, published on 29 Dec 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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.
