CVE-2020-17426
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 3.6.6.922. 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 handling of CR2 files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-11230.
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 confidenceFoxit Studio Photo 3.6.6.922 contains a memory corruption vulnerability in its CR2 (Canon RAW) file parser. The application fails to properly validate user-supplied data when parsing CR2 files, leading to memory corruption that can be leveraged for arbitrary code execution in the context of the current process. Exploitation requires the user to open a specially crafted malicious CR2 file.

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 if Foxit Studio Photo is installed on the system by looking in the program files directory (typically C:\Program Files\Foxit Studio Photo or C:\Program Files (x86)\Foxit Studio Photo), or by searching for the application in Add/Remove Programs in Windows Control Panel.Affected if The application Foxit Studio Photo is present on the system.
-
Determine installed versionRight-click on the Foxit Studio Photo executable (usually named FoxitStudioPhoto.exe) in the installation directory, select Properties, and check the Details tab for the File Version. Alternatively, locate the application in Add/Remove Programs and view the installed version displayed there.Affected if The installed version is exactly 3.6.6.922.
-
Identify CR2 file processing capabilityCheck if the application has CR2 file association or has been used to open CR2 files by searching for .cr2 file type associations in Windows registry under HKEY_CLASSES_ROOT\.cr2, or by reviewing recent file access logs if available.Affected if CR2 file types are associated with Foxit Studio Photo or CR2 files have been opened with this application.
If Foxit Studio Photo version 3.6.6.922 is installed and the application processes or has processed CR2 (Canon RAW) files, the environment is affected by this vulnerability.

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 dataUsers should refrain from opening CR2 files from untrusted or unknown sources. Organizations should implement file type restrictions and employ endpoint protection that monitors for suspicious file processing activity. Contact Foxit for available patches or updates.
