Secure Connect Gateway 5.0 - Application: Download of Code Without Integrity Check

CVE-2026-79963 is a high-severity download of code without integrity check vulnerability in Secure Connect Gateway 5.0 - Application from Dell, with a CVSS 3.1 base score of 7.4 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 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.

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 Download of Code Without Integrity Check vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to command execution.

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

The underlying weakness: Download of Code Without Integrity Check

The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code.

How developers prevent this class of flaw

  • Perform proper forward and reverse DNS lookups to detect DNS spoofing.
  • Encrypt the code with a reliable encryption scheme before transmitting.
  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
