CVSSv3.1: 4.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CWE-200 - Information exposure
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists in LibreOffice Calc, which supports COM.MICROSOFT.WEBSERVICE function to obtain data by URL. The application allows WEBSERVICE to take a local file URL (e.g file://) which can be used to inject local files into the spreadsheet without warning the user. Subsequent formulas can operate on that inserted data and construct a remote URL. A remote attacker can create a specially crafted document, trick the victim into opening it and use WEBSERVICE functionality to send arbitrary local files to the attacker's controlled server.
Install update from vendor's website.
