CVE: N/A
CWE: N/A

Last year I did some research on JavaScript API used in PDF reader. I found that if you provide a path to submitForm then this path will be created by Foxit PDF reader when opening the PDF, this is an *Arbitrary File Write*. Unfortunately I did not find a way to control the content of the file.....If you can control the content of the file then you can get *100% stable RCE*! This issue was fixed in Foxit PhantomPDF 10.1.5( https://www.foxit.com/support/security-bulletins.html). Addressed a potential issue where the application could be exposed to Arbitrary File Write vulnerability when executing the *submitForm* function. Attackers could exploit this vulnerability to create arbitrary files in the local system and inject the uncontrolled contents. Hou JingYi (@hjy79425575)
