According to its version, the Foxit PDF Reader application (previously named Foxit Reader) installed on the remote Windows host is prior to 2026.1. It is, therefore affected by multiple vulnerabilities:

  - The application's list box calculate array logic keeps stale references to page or form objects after they     are deleted or re-created, which allows crafted documents to trigger a use-after-free when the calculation     runs and can potentially lead to arbitrary code execution. (CVE-2026-3779)

  - The application allows PDF JavaScript and document/print actions (such as WillPrint/DidPrint) to update     form fields, annotations, or optional content groups (OCGs) immediately before or after redaction,     encryption, or printing. These scriptdriven updates are not fully covered by the existing redaction,     encryption, and printing logic, which, under specific document structures and user workflows, may cause a     small amount of sensitive content to remain unremoved or unencrypted as expected, or result in printed     output that slightly differs from what was reviewed on screen. (CVE-2026-3774)

  - The application's update service, when checking for updates, loads certain system libraries from a search     path that includes directories writable by lowprivileged users and is not strictly restricted to trusted     system locations. Because these libraries may be resolved and loaded from userwritable locations, a local     attacker can place a malicious library there and have it loaded with SYSTEM privileges, resulting in local     privilege escalation and arbitrary code execution. (CVE-2026-3775)

  - The application's installer runs with elevated privileges but resolves system executables and DLLs using     untrusted search paths that can include user-writable directories, allowing a local attacker to place     malicious binaries with the same names and have them loaded or executed instead of the legitimate system     files, resulting in local privilege escalation. (CVE-2026-3780)

  - The application does not validate the presence of required appearance (AP) data before accessing stamp     annotation resources. When a PDF contains a stamp annotation missing its AP entry, the code continues to     dereference the associated object without a prior null or validity check, which allows a crafted document     to trigger a null pointer dereference and crash the application, resulting in denial of service.
    (CVE-2026-3776)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
