Vulnerability details

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

The weakness exists due to type confusion error. A remote attacker can execute certain XFA FormCalc functions in crafted PDF files since the application could transform non-CXFA_Object to CXFA_Object by force without judging the data type and use the discrepant CXFA_Object directly.

Successful exploitation of the vulnerability may result in system compromise.

Affected software

Foxit PDF Editor (formerly Foxit PhantomPDF)
Foxit PDF Reader for Windows

Remediation

Update Foxit Reader to version 9.0.
Update Foxit PhantomPDF to version 8.3.5.
