Secure Connect Gateway 5.0 - Application: Relative Path Traversal

Published Updated By the CyberSecBulletin desk

CVE-2026-80133 is a high-severity relative path traversal vulnerability in Secure Connect Gateway 5.0 - Application from Dell, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 5.36.00.00 or later as the first without the flaw, so updating Secure Connect Gateway 5.0 - Application to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.71% chance of exploitation within 30 days, higher than 54% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Secure Connect Gateway 5.0 - Application to 5.36.00.00 or later or a later version.
  2. Update Secure Connect Gateway 5.0 - Appliance to 5.36.00.16 or later or a later version.
  3. Update Secure Connect Gateway to 5.36.00.00 or 5.36.00.16, whichever matches your release line, or a later version.
  4. Read the advisory on dell.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains a Relative Path Traversal vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to remote execution.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Relative Path Traversal

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.

How developers prevent this class of flaw

  • Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
