CWE-ID: CWE-843

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Foxit PDF Reader for Windows
Client/Desktop applications / Office applications
Foxit PDF Editor (formerly Foxit PhantomPDF)
Client/Desktop applications / Office applications

Vendor: Foxit Software Inc.

Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists when executing certain XFA functions in crafted PDF files since the application could transform non-CXFA_Object to CXFA_Object without judging the data type and use the discrepant CXFA_Object to get layout object directly. A remote attacker can trick the victim into opening a specially crafted file, trigger type confusion error and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation
Update to version 9.1.

Vulnerable software versions

Foxit PDF Reader for Windows: 8.0.0 - 9.0.1.1049
