What is CVE-2010-20114?
CVE-2010-20114 is a high-severity memory corruption vulnerability in VariCAD EN, published on 21 Aug 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
VariCAD EN up to and including version 2010-2.05 is vulnerable to a stack-based buffer overflow when parsing .dwb drawing files. The application fails to properly validate the length of input data embedded in the file, allowing a crafted .dwb file to overwrite critical memory structures. This flaw can be exploited locally by convincing a user to open a malicious file, resulting in arbitrary code execution.
