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
Blue Coat ProxySG before SGOS 4.3.4.1, 5.x before SGOS 5.4.5.1, 5.5 before SGOS 5.5.4.1, and 6.x before SGOS 6.1.1.1 allows remote authenticated users to execute arbitrary CLI commands by leveraging read-only administrator privileges and establishing an HTTPS session.

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 · high confidence

Blue Coat ProxySG contains a privilege escalation vulnerability where read-only administrators can execute arbitrary CLI commands by establishing an HTTPS session. The vulnerability exists in SGOS versions prior to 4.3.4.1, 5.x before 5.4.5.1, 5.5 before 5.5.4.1, and 6.x before 6.1.1.1. A read-only admin with network access can bypass intended restrictions to run commands at the full CLI level.

MitigationUpgrade Blue Coat ProxySG to SGOS 4.3.4.1, 5.4.5.1, 5.5.4.1, 6.1.1.1 or later. If immediate patching is not possible, restrict read-only admin access to trusted personnel and monitor for unauthorized command execution.

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 the SGOS version
    Log into the ProxySG CLI and run 'show version' or view the version in the management web interface
    Affected if The version is earlier than 4.3.4.1, between 5.0.0 and 5.4.5.0, between 5.5.0 and 5.5.4.0, or earlier than 6.1.1.1 on the 6.x branch
  2. Confirm read-only admin accounts exist
    Run 'show admin-users' in the CLI or review admin account settings in the management interface to list all configured administrators and their privilege levels
    Affected if Any read-only administrator accounts are configured on the device
  3. Verify HTTPS management interface is enabled
    Run 'show management' in the CLI or check the management settings in the web interface to see if HTTPS access is permitted
    Affected if HTTPS management is enabled and allows administrative access
  4. Check network exposure of management interface
    Attempt to reach the ProxySG management interface from your network segments or review firewall rules controlling access to port 443 on the device
    Affected if The HTTPS management port is reachable from networks that contain untrusted or unauthorized users

The environment is affected if the ProxySG runs a vulnerable SGOS version AND has read-only admin accounts configured with network access to the HTTPS management interface.

Upgrade available Upgrade to a release after 4.3.4
Interim mitigation

Upgrade Blue Coat ProxySG to SGOS 4.3.4.1, 5.4.5.1, 5.5.4.1, 6.1.1.1 or later. If immediate patching is not possible, restrict read-only admin access to trusted personnel and monitor for unauthorized command execution.

Recommended fix High confidence

SGOS 4.3.4.1 (for 4.x), SGOS 5.4.5.1 (for 5.x), SGOS 5.5.4.1 (for 5.5.x), or SGOS 6.1.1.1 (for 6.x)

  1. 1. Identify the current SGOS version running on the ProxySG device by accessing the Management Console or running 'show version' in the CLI.
  2. 2. Determine which upgrade path applies based on current version: if on 4.x branch, upgrade to SGOS 4.3.4.1; if on 5.x (before 5.4), upgrade to SGOS 5.4.5.1; if on 5.5.x, upgrade to SGOS 5.5.4.1; if on 6.x, upgrade to SGOS 6.1.1.1.
  3. 3. Download the appropriate SGOS firmware from the Blue Coat support portal (support.bluecoat.com).
  4. 4. Back up the current ProxySG configuration through the Management Console (Configuration > Archive > Backup).
  5. 5. Upload the new SGOS firmware through the Management Console (Maintenance > Firmware > Upload) or via CLI using 'firmware upload' command.
  6. 6. Reboot the ProxySG device to apply the new firmware.
  7. 7. After reboot, verify the new SGOS version is installed using 'show version' in the CLI.
  8. 8. Confirm the configuration was preserved and test that the vulnerability is mitigated.
Caveat Upgrading across major SGOS branches (e.g., 4.x to 5.x or 5.x to 6.x) may introduce behavioral changes; review Blue Coat release notes for compatibility concerns with existing policies and integrations
