Security readout for executives and security teams
Plain-English summary
CVE-2017-16813 affects Foxit MobilePDF for iOS before version 6.1. A specially malformed filename submitted through the app's Wi-Fi upload feature could make the app fail to parse the file and cause a denial of service. The known impact is app availability, not data theft or remote system compromise.
Executive priority
Treat this as a low-priority hygiene item unless legacy Foxit MobilePDF iOS use is confirmed in critical workflows. The known impact is denial of service, and sources do not show active exploitation or sensitive data exposure.
Technical view
The issue is a parsing failure in Foxit MobilePDF for iOS before 6.1 when handling a hexadecimal Unicode character in the Wi-Fi upload filename parameter. Public source data does not provide CVSS, CWE, exploit maturity, or detailed remediation beyond the affected version boundary.
Likely exposure
Exposure is most likely in environments with managed or unmanaged iOS devices still running Foxit MobilePDF before 6.1 and using the Wi-Fi upload feature. Current exposure is probably limited because the affected app version is old, but inventory evidence is required.
Exploitation context
The source bundle does not indicate active exploitation, and the CVE is not marked in KEV. The described trigger requires interaction with the app's Wi-Fi upload handling and a malformed filename parameter. No broader exploit chain is documented in the provided sources.
Researcher notes
Evidence is sparse: the public record names the affected app, version boundary, Wi-Fi upload vector, and parsing condition, but provides no CVSS, CWE, proof-of-concept status, or vendor fix detail beyond versions before 6.1 being affected.
Mitigation direction
- Inventory iOS devices for Foxit MobilePDF installations and versions.
- Upgrade affected Foxit MobilePDF for iOS installations to 6.1 or later where supported.
- Consult Foxit's security bulletin for vendor-specific remediation guidance.
- Restrict or avoid Wi-Fi upload use on affected versions until remediated.
Validation and detection
- Confirm whether any iOS devices run Foxit MobilePDF before 6.1.
- Check MDM or app inventory records for unmanaged legacy installations.
- Verify whether Wi-Fi upload is enabled or used in affected deployments.
- Review support logs for unexplained Foxit MobilePDF crashes during file upload handling.
