Detailsinfo

A vulnerability, which was classified as critical, was found in VariCAD EN up to 2010-2.05. This affects an unknown code block of the component dwb Drawing File Parser. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed by n00b. The advisory is shared at raw.githubusercontent.com. This vulnerability is uniquely identified as CVE-2010-20114 since 08/20/2025. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation.
