CVE-2026-41119 Dell CVE debrief

A medium-severity vulnerability in Dell Live Optics collectors allows remote unauthenticated attackers to bypass SSL/TLS certificate validation, potentially enabling man-in-the-middle attacks that compromise data confidentiality and integrity. The vulnerability stems from improper certificate validation (CWE-295) in both Windows and Personal Edition collector software. Dell has published security advisory DSA-2026-221 with remediation guidance.

Who should care

Organizations using Dell Live Optics for infrastructure assessment and performance monitoring should prioritize this update. Security teams monitoring certificate validation behaviors in endpoint software should include Live Optics collectors in verification scope. Network defenders should assess whether collector communications traverse untrusted network segments where MITM positioning is feasible.

Technical summary

The Dell Live Optics collector software fails to properly validate SSL/TLS certificates during secure communications. This improper validation (CWE-295) creates conditions where an attacker positioned in the network path could present invalid or fraudulent certificates without detection by the collector. Successful exploitation requires network access to intercept collector communications and user interaction or specific network conditions (AC:H, UI:R per CVSS vector). The attack results in high impact to confidentiality and integrity (C:H, I:H) with no direct availability impact. Both Windows and Personal Edition collector variants are affected.

Defensive priority

medium

Recommended defensive actions

  • Apply Dell security update DSA-2026-221 for affected Live Optics collector installations
  • Verify collector SSL/TLS certificate validation behavior in network traffic monitoring
  • Review collector endpoint communications for unexpected certificate authorities or validation failures
  • Consider network segmentation for collector management interfaces pending patch verification
