IrfanView vulnerability analysis and mitigation

IrfanView CADImage Plugin contains a remote code execution vulnerability related to DWG file parsing memory corruption. The vulnerability, identified as CVE-2025-7270, was discovered by Rocco Calvi and reported to the vendor on February 20, 2025. The issue affects IrfanView CADImage Plugin installations and requires user interaction, specifically opening a malicious file or visiting a malicious page (Zero Day Initiative).

The vulnerability stems from improper validation of user-supplied data during the parsing of DWG files, which can result in a memory corruption condition (CWE-119). The vulnerability has received a CVSS v3.0 base score of 7.8 (High), with the following vector: CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. This indicates local attack vector, low attack complexity, no privileges required, user interaction required, and high impacts on confidentiality, integrity, and availability (Zero Day Initiative).

If successfully exploited, this vulnerability allows attackers to execute arbitrary code in the context of the current process. The high CVSS score reflects the severe potential impact on system security, with possible complete compromise of system confidentiality, integrity, and availability (Zero Day Initiative).

The vulnerability has been fixed in IrfanView CADImage Plugin version 4.72. Users should upgrade to this version or later to mitigate the risk (Zero Day Initiative).
