CVE-2024-49597
📋 TL;DR
Dell Wyse Management Suite versions 4.4 and earlier have a vulnerability where attackers with high privileges and remote access can bypass protection mechanisms by making excessive authentication attempts. This affects organizations using Dell Wyse Management Suite for managing thin clients. The vulnerability allows circumvention of security controls that should limit authentication attempts.
💻 Affected Systems
- Dell Wyse Management Suite
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
High-privileged attacker bypasses all authentication protection mechanisms, potentially gaining unauthorized administrative access to the Wyse Management Suite, leading to complete system compromise and lateral movement across managed endpoints.
Likely Case
Privileged attacker bypasses rate-limiting or lockout mechanisms to perform credential stuffing or brute-force attacks against administrative accounts, potentially compromising the management console.
If Mitigated
With proper network segmentation and access controls, impact is limited to the management interface only, preventing lateral movement to managed endpoints.
🎯 Exploit Status
Exploitation requires high privileged access, but the vulnerability itself involves simple bypass of authentication attempt restrictions.
