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
Dell Secure Connect Gateway (SCG) 5.0 Appliance and Application version(s) 5.28.00.xx to 5.32.00.xx, contain(s) an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability. A high privileged attacker within the management network could potentially exploit this vulnerability, leading to remote execution.

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

Dell Secure Connect Gateway versions 5.28.00.xx through 5.32.00.xx contain a path traversal vulnerability that allows a high-privileged attacker to access files outside restricted directories, potentially leading to remote code execution.

MitigationApply vendor-supplied patches when available; until then, restrict management network access to trusted personnel only and monitor for unauthorized file access attempts.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Determine installed Dell Secure Connect Gateway version
    Access the appliance admin interface and navigate to System or About section to view the firmware/software version. Alternatively, check the version via CLI if available (e.g., show version or system info commands).
    Affected if The displayed version falls within the range 5.28.00.00 through 5.32.00.xx (any version >= 5.28.00.00 but < 5.34.00.00).
  2. Verify management interface accessibility
    Confirm whether the Dell Secure Connect Gateway management interface (web UI or API endpoints) is exposed to untrusted networks or the public internet. Review firewall rules and access control lists restricting access to port 443/8443 or the configured management port.
    Affected if The management interface is reachable from untrusted networks without VPN or IP restrictions.
  3. Review system logs for anomalous file access patterns
    Examine Dell Secure Connect Gateway logs (typically found in /var/log, system logs, or the admin UI logs section) for entries containing unusual path traversal patterns such as '../', '..\', or attempts to access system files outside expected directories.
    Affected if Log entries show requests with directory traversal sequences or access to sensitive system files (e.g., /etc/passwd, Windows\System32) that were not initiated by legitimate administrators.
  4. Check for unauthorized privileged access
    Review audit logs or authentication records for any high-privileged account (administrator, super-user) logins that were not performed by known authorized personnel, especially from unexpected IP addresses or at unusual times.
    Affected if There are records of high-privileged account activity that cannot be attributed to legitimate administrators.

You are affected if your installed Dell Secure Connect Gateway version is 5.28.00.00 or higher but below 5.34.00.00, AND the management interface is accessible to untrusted users or there are indicators of path traversal attempts in logs.

Recommended fix High confidence

Secure Connect Gateway 5.34.00.00 or later

  1. 1. Back up the current Secure Connect Gateway configuration and data according to Dell's backup procedures.
  2. 2. Schedule a maintenance window for the upgrade process.
  3. 3. Download the Secure Connect Gateway version 5.34.00.00 or later from the Dell Support site (support.dell.com).
  4. 4. Follow Dell's documented upgrade procedure for SCG, typically via the management interface or CLI.
  5. 5. Verify the upgrade was successful by logging into the management console.
  6. 6. Confirm the new version is 5.34.00.00 or higher.
  7. 7. Test that critical functionality and the path traversal fix are working correctly.
