CVE-2025-24049
📋 TL;DR
This command injection vulnerability in Azure CLI allows local attackers to execute arbitrary commands with elevated privileges. It affects users running vulnerable versions of Azure CLI on their systems. Attackers can exploit this to gain unauthorized access and control over affected systems.
💻 Affected Systems
- Azure Command Line Interface (CLI)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with administrative privileges, allowing data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Local privilege escalation leading to unauthorized access to sensitive data and system resources within the compromised environment.
If Mitigated
Limited impact with proper access controls and monitoring, potentially only affecting isolated user sessions.
🎯 Exploit Status
Requires local access and some knowledge of Azure CLI commands. No public exploit code available at this time.
