How the CVE Works
The vulnerability (CVE-2025-7253) resides in the IrfanView CADImage Plugin’s handling of DWG files. Due to insufficient validation of user-supplied data 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 current process. Exploitation requires user interaction, such as opening a malicious file or visiting a compromised webpage. The flaw stems from improper bounds checking, allowing heap or stack-based corruption.
