Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The ASG and ProxySG management consoles are susceptible to a session hijacking vulnerability. A remote attacker, with access to the appliance management interface, can hijack the session of a currently logged-in user and access the management console.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is a session hijacking vulnerability in the ASG and ProxySG management consoles. A remote attacker with access to the appliance management interface can intercept or predict session identifiers to take over an active session of a legitimate logged-in user, thereby gaining unauthorized administrative access to the management console.

MitigationApply the vendor patch from Broadcom when available. In the interim, restrict management console access to trusted IP addresses/networks via firewall rules and enforce short session timeouts to reduce the window of opportunity for hijacking.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify product and version
    Log into the management console or use the CLI to determine the exact product (ASG or ProxySG) and installed version number
    Affected if The installed version falls within >= 6.7.4 but < 6.7.4.10, OR >= 7.1 but < 7.2.0.1
  2. Confirm management console is active
    Verify that the management interface (HTTP/HTTPS) is currently running and accessible on the appliance
    Affected if The management console is enabled and reachable on the network
  3. Check session token configuration
    If accessible, inspect the session management settings in the management console configuration or CLI for session timeout and token generation settings
    Affected if Long session timeouts or default session token configuration are in use, indicating a larger attack window for hijacking
  4. Review management access controls
    Check firewall or access control settings to determine if management console is exposed to untrusted networks
    Affected if Management interface is accessible from untrusted or public network segments

You are affected if the installed version is within the vulnerable ranges AND the management console is accessible to potential attackers.
