How the CVE Works
CVE-2025-7250 is a critical remote code execution vulnerability in IrfanView’s CADImage Plugin when parsing DWG files. The flaw stems from improper boundary checks when processing user-supplied DWG files, leading to an out-of-bounds read. Attackers can craft a malicious DWG file that, when opened, triggers memory corruption, allowing arbitrary code execution within the context of the application. Exploitation requires user interaction (e.g., opening a malicious file). The lack of input validation enables attackers to bypass memory safeguards, potentially leading to full system compromise.
