CVE-2020-12803
CVSS v2.0
7.1
High
| Vector | AV:N/AC:M/Au:N/C:N/I:C/A:N |
Name of the Vulnerable Software and Affected Versions
LibreOffice versions prior to 6.4.4
Description
The issue is related to a form submission feature in ODF documents, which can be used to submit data to a URI, such as an external web server. Prior to version 6.4.4, LibreOffice allowed forms to be submitted to any URI, including file: URIs, enabling form submissions to overwrite local files. User-interaction is required to submit the form. To avoid the possibility of malicious documents, this feature has now been limited to http[s] URIs, removing the possibility to overwrite local files.
Recommendations
For LibreOffice versions prior to 6.4.4, update to version 6.4.4 or later to limit form submissions to http[s] URIs and prevent the possibility of overwriting local files. As a temporary workaround, consider disabling form submissions to file: URIs to minimize the risk of exploitation. Restrict access to sensitive local files to prevent potential data integrity issues.
