The version of Foxit Reader installed on the remote Windows host is prior to 9.4. It is, therefore, affected by multiple vulnerabilities:
An out-of-bounds read/write vulnerability and crash when handling XFA element attributes. (CVE-2018-3956)
A signature validation bypass vulnerability which could lead to incorrect validation results.
(CVE-2018-18688, CVE-2018-18689)
Flaws in how PDF files are processed/handled could lead to arbitrary code execution. An attacker can exploit this by convincing a user to open a specially crafted file in order to cause the execution of arbitrary code. (CVE-2019-6728,CVE-2019-6729)
Additionally, the application was affected by multiple potential information disclosure, denial of service, and remote code execution vulnerabilities.
