CVE-2020-8881
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Studio Photo 3.6.6.916. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of TIF files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-9774.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA remote code execution vulnerability exists in Foxit Studio Photo 3.6.6.916 when processing maliciously crafted TIF files. The vulnerability stems from the application failing to validate the existence of an object before performing operations on it, leading to a use-after-free or null pointer dereference condition that can be leveraged to execute arbitrary code in the context of the current process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Foxit Studio Photo installationCheck for the application in the system: On Windows, look in Programs and Features (Add/Remove Programs) or check C:\Program Files\Foxit Studio Photo for the executable. On macOS, check /Applications for Foxit Studio Photo.app.Affected if Foxit Studio Photo is present on the system
-
Identify installed versionRight-click the Foxit Studio Photo executable (typically Foxit Studio Photo.exe on Windows or the app bundle on macOS), select Properties, then check the Details tab for the version number. Alternatively, run 'Get-ItemProperty' in PowerShell for installed programs or check the uninstall registry key at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall.Affected if The version number is 3.6.6.916 or any version up to and including 3.6.6.918 (e.g., 3.6.6.917, 3.6.6.918)
-
Confirm TIF processing capabilityLaunch the application and attempt to open a TIF file using File > Open or drag-and-drop. The vulnerability affects the TIF file parsing functionality.Affected if The application successfully opens and processes TIF image files
-
Assess exposure to untrusted TIF filesReview whether the application has access to network-shared TIF files, receives TIF attachments from external sources, or processes TIF files from untrusted locations. Check email gateways or download folders that may contain TIF files processed by this application.Affected if The application can process TIF files from untrusted or external sources
A system is affected if Foxit Studio Photo version 3.6.6.916 through 3.6.6.918 is installed and the application processes TIF files, particularly from untrusted sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataOrganizations should block or restrict processing of untrusted TIF files in Foxit Studio Photo, implement endpoint detection mechanisms, and consider removing the software if no business need exists. User awareness training should emphasize not opening unexpected image files.
