Security readout for executives and security teams
Plain-English summary
CVE-2019-25252 is a cross-site request forgery issue in Teradek VidiU Pro. If an administrator is logged into the device and visits a malicious page, the attacker may cause an administrative password change. This can disrupt streaming operations and lock out legitimate administrators.
Executive priority
Treat as a focused remediation item for environments using Teradek VidiU Pro. It is not confirmed as actively exploited, but password takeover can interrupt broadcast or streaming operations. Prioritize inventory, access restriction, and vendor guidance review.
Technical view
The issue is CWE-352 in Teradek VidiU Pro versions listed as 3.0.3, 3.0.2, and 2.4.10. The password-change function lacks proper request validation. CVSS v4.0 is 5.1 with network attack vector, low complexity, no privileges required, and user interaction required.
Likely exposure
Exposure is most relevant where VidiU Pro administrative interfaces are reachable from administrator browsers and admins remain logged in. Risk increases if management access is available from general user networks or the internet. The provided sources do not establish internet-wide exploitation or a vendor patch status.
Exploitation context
A public ExploitDB reference exists, but the source bundle does not show CISA KEV listing or active exploitation. Successful abuse requires administrator interaction: a logged-in admin must visit attacker-controlled or compromised content that triggers an unauthorized password-change request.
Researcher notes
The bundle cites CVE, Zero Science Lab, ExploitDB, and Teradek’s site. It lists affected versions but provides no confirmed fixed version or mitigation from the vendor. Avoid assuming patch availability. KEV is false in the supplied data.
Mitigation direction
- Check Teradek guidance for firmware updates or vendor-recommended remediation.
- Restrict VidiU Pro administration to trusted management networks.
- Avoid exposing the administrative interface to the internet.
- Require administrators to log out after device management sessions.
- Use network controls to limit which hosts can reach device management pages.
- Review and rotate device administrator credentials where exposure is suspected.
Validation and detection
- Inventory Teradek VidiU Pro devices and record firmware versions.
- Identify devices running 3.0.3, 3.0.2, or 2.4.10.
- Confirm whether administrative interfaces are internet-accessible or broadly reachable internally.
- Review recent password changes and administrator lockout events.
- Verify management access is restricted to approved administrator workstations.
- Check vendor resources for updated firmware or formal advisory guidance.
