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
An authentication bypass in the admin web console of Ivanti CSA before 5.0.3 allows a remote unauthenticated attacker to gain administrative access

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

An authentication bypass vulnerability exists in the admin web console of Ivanti Connect Secure Access (CSA) before version 5.0.3. The flaw allows a remote, unauthenticated attacker to bypass authentication mechanisms and gain administrative access to the device, potentially enabling full system compromise.

MitigationUpgrade Ivanti CSA to version 5.0.3 or later to apply the authentication bypass patch. If immediate upgrading is not feasible, restrict administrative web console access to trusted networks only using firewall rules or VPN access controls.

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 Ivanti CSA installation
    Locate the Ivanti Cloud Services Appliance in your environment. Check installed software listings, running services, or network documentation for systems running Ivanti CSA.
    Affected if The system is running Ivanti Cloud Services Appliance (CSA)
  2. Check CSA version number
    Access the admin web console or use system commands to retrieve the installed version. Common methods include logging into the admin interface and viewing the About/System Info page, or running version commands via CLI if available.
    Affected if The installed version is lower than 5.0.3 (e.g., 5.0.2, 5.0.1, earlier releases)
  3. Confirm admin web console is in use
    Verify that the admin web console interface is accessible or has been configured. This is the primary attack surface for this vulnerability.
    Affected if The admin web console is accessible on the appliance (this is the default configuration for CSA)
  4. Review network exposure of admin interface
    Check firewall rules, ACLs, or VPN settings to determine if the admin web console is exposed to untrusted networks. Examine whether external access is permitted to ports 443/8443 or similar admin endpoints.
    Affected if The admin web console is reachable from untrusted networks or the internet

You are affected if the system runs Ivanti Cloud Services Appliance with a version lower than 5.0.3 and the admin web console is accessible, even internally.

Upgrade available Upgrade to 5.0.3 or later
Fixed in 5.0.3
Interim mitigation

Upgrade Ivanti CSA to version 5.0.3 or later to apply the authentication bypass patch. If immediate upgrading is not feasible, restrict administrative web console access to trusted networks only using firewall rules or VPN access controls.

Recommended fix High confidence

5.0.3

  1. Check the current version of Ivanti Cloud Services Appliance by accessing the admin web console or using system information commands
  2. If the current version is below 5.0.3, plan and schedule an upgrade window
  3. Backup the current appliance configuration and any critical data before proceeding
  4. Download Ivanti Cloud Services Appliance version 5.0.3 or later from the official Ivanti download portal
  5. Follow the official upgrade documentation to apply the update to the CSA appliance
  6. After upgrade completes, verify the version shows 5.0.3 or higher in the admin console
  7. Confirm the authentication bypass vulnerability is resolved by testing admin login functionality
