CVE-2024-11547
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIrfanView DWG File Parsing Memory Corruption Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of IrfanView. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DWG files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24732.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIrfanView contains a memory corruption vulnerability in its DWG file parsing functionality. The lack of proper validation of user-supplied data during DWG file processing leads to memory corruption, which can be exploited to achieve arbitrary code execution within the context of the current process. Exploitation requires user interaction—specifically opening a malicious DWG file.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm IrfanView installationCheck if IrfanView is installed on the system by searching for the program executable (irfanview.exe) in common installation directories such as C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView, or by checking the Add/Remove Programs list in Control Panel.Affected if IrfanView is found installed on the system.
-
Identify installed IrfanView versionRight-click the IrfanView executable (irfanview.exe), select Properties, and navigate to the Details tab to view the File Version. Alternatively, launch IrfanView and navigate to Help > About IrfanView to display the version number.Affected if The installed version is exactly 4.67.
-
Check DWG file handling capabilityAttempt to open a DWG file with IrfanView or check if DWG file associations are registered. DWG files typically use the .dwg extension and IrfanView requires plugins (such as DWG.dll) to handle this format.Affected if IrfanView has DWG file handling capability enabled or has the DWG plugin installed and can open .dwg files.
A user is affected if IrfanView version 4.67 is installed AND DWG file handling functionality is available and can be used to process DWG files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUsers should avoid opening DWG files from untrusted or unknown sources. Maintain vigilance with email attachments or downloads containing DWG files. Apply any vendor patches for IrfanView when available.
