How the CVE Works
The vulnerability (CVE-2025-7249) resides in the IrfanView CADImage Plugin’s handling of DWG files. Due to insufficient validation of user-supplied input during DWG file parsing, a memory corruption condition occurs. Attackers can craft a malicious DWG file that, when opened by the victim, triggers memory corruption, leading to arbitrary code execution in the context of the application. This requires user interaction (e.g., opening a malicious file). The flaw stems from improper bounds checking, allowing overwriting of critical memory structures.
