🛠 Technical Breakdown

• CVE ID: CVE-2025-49457
• Severity: Critical
• CVSS Score: 9.1 (Estimated)
• Affected Platforms: Zoom Desktop Client for Windows
• Attack Vector: Local privilege escalation (LPE)

Vulnerability Mechanism:

1. Zoom’s update service runs with SYSTEM privileges.
2. Due to insecure file handling and DLL search order hijacking, a local attacker could replace or inject malicious DLLs.
3. On service restart (e.g., system reboot or manual update), the injected DLL executes with SYSTEM-level permissions.

🎯 Impact Analysis

• Full System Compromise:
  • Attackers gain SYSTEM privileges, allowing them to disable security tools, create new admin accounts, and alter system configurations.
• Persistence & Stealth:
  • Perfect for APT-style operations, where attackers maintain long-term access without detection.
• Enterprise Risk:
  • If exploited in corporate environments, this flaw could pivot attacks across entire networks.
