Security readout for executives and security teams
Plain-English summary
This vulnerability can crash Foscam Video Management System 1.1.6.6 when a local user enters an oversized UID while adding a device. The business impact is availability loss for the management application, not confirmed data theft or remote compromise. Treat it as a workstation or operations-system resilience issue where this software is still used.
Executive priority
Medium priority. Address during normal vulnerability remediation unless this software supports critical video operations. Escalate if outages would disrupt physical security monitoring or if untrusted users can access the affected application.
Technical view
CVE-2019-25437 is a CWE-121 stack-based buffer overflow in the UID field of Foscam Video Management System 1.1.6.6. The CVSS v4.0 score is 6.7. The vector indicates local access, low complexity, no privileges, and required user interaction, with high vulnerable-system availability impact only.
Likely exposure
Exposure appears limited to environments running Foscam Video Management System version 1.1.6.6. The described attack is local and tied to device-addition workflow input, so internet-facing service exposure is not indicated by the provided sources.
Exploitation context
A public Exploit-DB reference exists, but the CVE is not listed as CISA KEV in the provided bundle. The sources support denial-of-service through application crash, not active exploitation, privilege escalation, or code execution.
Researcher notes
The public description is narrow: UID input during device addition can crash the application when Login Check is invoked. Evidence supports local denial of service only. No vendor patch details are included in the provided sources, so remediation should be confirmed against current Foscam guidance.
Mitigation direction
- Inventory systems for Foscam Video Management System 1.1.6.6.
- Check Foscam guidance for fixed or supported versions.
- Restrict use of the application to trusted operators.
- Avoid untrusted device-addition data in affected installations.
- Consider removing or replacing unsupported affected software.
Validation and detection
- Confirm installed Foscam Video Management System version.
- Review endpoint software inventory for version 1.1.6.6.
- Check operational logs for repeated application crashes during device addition.
- Verify vendor guidance before applying upgrades or compensating controls.
