Exploitation Summary
EIP tracks 2 public exploits for CVE-2010-20114.
PoCs published by n00b, n00b, dookie, MC, jduck, including Metasploit module exploits/windows/fileformat/varicad_dwb.
AI-analyzed exploit summary This exploit demonstrates a local buffer overflow in VariCAD 2010-2.05 EN via a malicious .DWB file, leveraging a memcpy() overflow to overwrite exception handlers and execute shellcode. The PoC includes shellcode for both a calculator payload and a bind shell.
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.
