Security readout for executives and security teams
Plain-English summary
CVE-2020-17404 affects Foxit Studio Photo 3.6.6.922. A crafted PSD file or malicious page could trigger memory corruption and let an attacker run code as the user. The victim must open a malicious file or visit attacker-controlled content, so exposure is concentrated on endpoints using this older image-editing software.
Executive priority
Treat this as a high-priority endpoint remediation item if Foxit Studio Photo is present. Business urgency is driven by potential user-level code execution from content handling, balanced by the need for user interaction and no source-backed evidence of active exploitation.
Technical view
The flaw is in PSD file handling and is classified as CWE-787. Improper validation of user-supplied data can cause a write past the end of an allocated structure, enabling code execution in the current process. The CVSS v3.0 score is 7.8 with user interaction required and high confidentiality, integrity, and availability impact.
Likely exposure
Likely exposure is limited to systems with Foxit Studio Photo 3.6.6.922 installed, especially where users open PSD files from email, downloads, web pages, or shared folders. The provided sources do not identify additional affected versions.
Exploitation context
The sources describe remote attacker code execution, but require user interaction: opening a malicious file or visiting a malicious page. CISA KEV status is false in the bundle, and no cited source states active exploitation.
Researcher notes
The record attributes the issue to ZDI-CAN-11191 and ZDI-20-1079. Evidence is strong for affected product, version, file format, weakness class, and impact. The source bundle does not provide exploit availability, observed exploitation, or a specific fixed version.
Mitigation direction
- Inventory endpoints for Foxit Studio Photo 3.6.6.922.
- Check Foxit security guidance for fixed or supported versions.
- Remove the affected version where it is no longer required.
- Block or quarantine untrusted PSD attachments where feasible.
- Warn users not to open PSD files from unknown sources.
Validation and detection
- Confirm installed Foxit Studio Photo versions on managed endpoints.
- Review software inventory for version 3.6.6.922 specifically.
- Check email and web controls for PSD handling policies.
- Verify remediation evidence against Foxit security bulletin guidance.

Out-of-bounds Write
Out-of-bounds Write represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
