How the CVE Works
The vulnerability exists in the IrfanView CADImage Plugin when parsing DXF files. Due to insufficient validation of user-supplied data, the plugin fails to check boundaries when reading data from a malicious DXF file. This leads to an out-of-bounds read, where an attacker-controlled input can trigger memory corruption. By crafting a specially designed DXF file, an attacker can exploit this flaw to execute arbitrary code within the context of the application. The exploit requires user interaction (opening the malicious file), but successful exploitation allows full remote code execution.

What Undercode Say
Analytics:
– `gdb ./IrfanView` (Debug crash dump)
– `python3 exploit_dxf.py` (PoC script)
– `edb –run IrfanView` (Memory analysis)
How Exploit:
- Craft malicious DXF file with oversized header
- Trigger OOB read via malformed entity data
- Overwrite EIP for code execution
Protection from this CVE:
- Update to latest plugin version
- Disable DXF file parsing
- Enable DEP/ASLR mitigations
Impact:
- Full system compromise
- Arbitrary code execution
- Low user interaction required
