Subject: [CVE-2020-13958] Apache OpenOffice - Unrestricted actions leads to
arbitrary code execution in crafted documents
CVE-2020-13958 Unrestricted actions leads to arbitrary code execution in crafted documents
Fixed in Apache OpenOffice 4.1.8
Description
A vulnerability in Apache OpenOffice scripting events allows an attacker to construct
documents containing hyperlinks pointing to an executable on the target users file system.
These hyperlinks can be triggered unconditionally. In fixed versions no internal protocol
may be called from the document event handler and other hyperlinks require a control-click.
Severity: Low
There are no known exploits of this vulnerability.
A proof-of-concept demonstration exists.
Vendor: The Apache Software Foundation
Versions Affected
Apache OpenOffice 4.0.0, 4.0.1, 4.1.0, 4.1.1, 4.1.2, 4.1.3, 4.1.4, 4.1.5, 4.1.6, and 4.1.7
OpenOffice.org versions may also be affected.
Mitigation
Install Apache OpenOffice 4.1.8 for the latest maintenance and cumulative security fixes.
