Event History
Frequently Asked Questions
Which deployments are exposed to this issue?
SRX Series devices are exposed when the custom URL-feed feature is configured and the device processes responses from a custom URL-feed server. The vulnerability is in the Unified Threat Management daemon (utmd).
What does an attacker need to exploit it?
An attacker must be able to provide a malicious response from a configured custom URL-feed server. No authentication or user interaction is required, but exploitation has high attack complexity.
What is the potential impact of successful exploitation?
Successful exploitation allows an unauthenticated network attacker to commit arbitrary device configuration with root privileges. This can affect confidentiality, integrity, and availability.
