CVE-2020-17423
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 ARW files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-11196.
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 heap-based buffer overflow vulnerability in Foxit Studio Photo 3.6.6.922 allows remote code execution via malicious ARW (Sony raw image) files. The flaw stems from insufficient validation of user-supplied data length before copying into a heap buffer, enabling an attacker to overwrite memory and 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 is installedCheck the program installation directory (typically C:\Program Files\Foxit Studio Photo or C:\Program Files (x86)\Foxit Studio Photo) or review installed programs via Windows Control Panel > Programs and FeaturesAffected if Foxit Studio Photo is present on the system
-
Determine the installed versionRight-click the Foxit Studio Photo executable, select Properties, and check the File Version under the Details tab, or use the program's About/Help menuAffected if The version is exactly 3.6.6.922
-
Confirm ARW file processing capabilityVerify the application can open and process ARW files by checking File > Open supported formats or attempting to open a sample ARW fileAffected if ARW files can be opened by the application
-
Review recent ARW file processing activityCheck the application's recent files list, Windows prefetch data, or file association history for ARW files opened around the time of potential exposureAffected if ARW files from untrusted or unknown sources have been opened using Foxit Studio Photo
If Foxit Studio Photo version 3.6.6.922 is installed AND has been used to open ARW files, the environment is affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 dataUpdate Foxit Studio Photo to the latest patched version. Until a patch is available, avoid opening ARW files from untrusted sources and employ endpoint protection to detect malicious file processing.
