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
Server-Side Request Forgery (SSRF) in Citrix SD-WAN Standard/Premium Editions on or after 11.4.0 and before 11.4.4.46 allows an attacker to disclose limited information from the appliance via Access to management IP.

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

Server-Side Request Forgery (SSRF) vulnerability in Citrix SD-WAN Standard/Premium Editions versions 11.4.0 through 11.4.4.45 allows unauthenticated attackers to make the appliance perform requests to internal management IPs, potentially exposing limited sensitive information from the network device.

MitigationUpgrade Citrix SD-WAN to version 11.4.4.46 or later to remediate this vulnerability. If immediate upgrade is not possible, restrict management interface access to trusted networks only.

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 SD-WAN firmware version
    Log into the SD-WAN web interface or CLI and navigate to the system information or about section to retrieve the current firmware version. Alternatively, use the 'show system' or 'show version' command in the CLI.
    Affected if The displayed version is 11.4.0 through 11.4.4.45 inclusive.
  2. Confirm the exact version number
    Record the full version string exactly as shown (for example, 11.4.3.12 or 11.4.4.45). Some interfaces may show only the major.minor version, so check all available version fields.
    Affected if The version starts with 11.4. and the build number is below 46.
  3. Check if the management interface is network-accessible
    Review the network configuration to determine if the SD-WAN management interface (HTTP/HTTPS on ports 80/443 or the appliance's management IP) is reachable from untrusted networks or the public internet.
    Affected if The management interface is exposed to networks that are not explicitly trusted.
  4. Verify the SD-WAN model
    Confirm the specific SD-WAN hardware model (1000, 110, 1100, 2000, 210, 2100, 400, or 4000) from the device label or system information.
    Affected if The model is one of the listed affected models and the firmware version is in the vulnerable range.

A user is affected if their Citrix SD-WAN device runs firmware version 11.4.0 through 11.4.4.45 and has its management interface accessible from untrusted networks.

Upgrade available Upgrade to 11.4.4.46 or later
Fixed in 11.4.4.46
Interim mitigation

Upgrade Citrix SD-WAN to version 11.4.4.46 or later to remediate this vulnerability. If immediate upgrade is not possible, restrict management interface access to trusted networks only.

Recommended fix High confidence

Upgrade to SD-WAN firmware version 11.4.4.46 or later

  1. 1. Back up the current SD-WAN configuration before initiating any upgrade.
  2. 2. Download the fixed firmware version 11.4.4.46 (or later) from the Citrix support portal at support.citrix.com.
  3. 3. Upload the firmware to the SD-WAN appliance via the web management interface or CLI.
  4. 4. Initiate the firmware upgrade process and monitor for successful completion.
  5. 5. After upgrade, verify the appliance is operational and confirm the management interface is accessible.
  6. 6. Test that the SSRF vulnerability is mitigated by confirming the management IP access behaves as expected.
Caveat Standard firmware upgrade procedure; ensure configuration backup before proceeding
