CVE-2025-7263: IrfanView CADImage Plugin CGM File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability
IrfanView CADImage Plugin CGM File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of IrfanView CADImage Plugin. 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 CGM files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26170.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Mitigate exploitation by blocking users from opening untrusted CGM files or visiting untrusted web pages (user interaction is required).
- Compensating control
Use network/application controls to block or restrict access to sites that could deliver the malicious page or file needed for exploitation (user interaction required).
- Compensating control
Identify systems with the IrfanView CADImage Plugin and restrict exposure so untrusted users cannot supply CGM files to IrfanView CADImage Plugin for parsing.
