CVE-2026-68502 in LazyOwn
Summary
by MITRE • 07/31/2026
LazyOwn RedTeam/APT Framework is an AI-powered C2 and red-team operations framework. Prior to 0.2.154, LazyOwn's lazyc2.py registers an unauthenticated Socket.IO input event handler that dispatches data.get('value') to LazyOwnShell.one_cmd, reaching LazyOwnShell.do_cmd and subprocess.call(command, shell=True), allowing unauthenticated remote code execution in the C2 process. This issue is fixed in 0.2.154.

The vulnerability identified in LazyOwn RedTeam/APT Framework represents a critical remote code execution flaw that undermines the security posture of red-team operations infrastructure. This weakness exists in the lazyc2.py component where an unauthenticated Socket.IO event handler is registered to process incoming data without proper authentication or input validation. The flaw allows any remote attacker to submit malicious payloads through the Socket.IO interface and execute arbitrary commands on the Command and Control server with the privileges of the C2 process itself.
The technical implementation of this vulnerability follows a clear chain of command execution that begins with the registration of an unauthenticated event handler in the Socket.IO framework. When data is received, the system directly extracts value from the data dictionary without any sanitization or validation checks. This raw data is then passed through LazyOwnShell.one_cmd method and subsequently dispatched to LazyOwnShell.do_cmd which ultimately invokes subprocess.call with shell=True parameter. This design pattern creates a direct path for arbitrary command injection attacks, as the shell=True argument enables shell interpretation of the command string, making it vulnerable to shell metacharacters and command chaining.
The operational impact of this vulnerability is severe for organizations relying on LazyOwn for security testing and red-team operations. An unauthenticated attacker can execute commands on the C2 server without requiring any credentials or authorization, potentially leading to complete compromise of the red-team infrastructure. This vulnerability undermines the trust model of the framework since it allows attackers to gain control over the very system designed to conduct authorized penetration testing activities. The implications extend beyond simple command execution as attackers could escalate privileges, exfiltrate sensitive test data, or use the compromised C2 server as a launch point for further attacks against target networks.
This vulnerability aligns with CWE-78 and CWE-94 categories, representing both shell injection and code injection flaws that are commonly exploited in web application and framework security breaches. The ATT&CK framework categorizes this issue under T1059.001 - Command and Scripting Interpreter with Shell Scripting as the attack technique, with potential progression to T1078 - Valid Accounts and T1566 - Phishing for credentials if the compromised C2 server is used for further reconnaissance. The vulnerability also demonstrates poor input validation practices and inadequate authentication mechanisms that are fundamental security misconfigurations in modern security frameworks.
Mitigation strategies should include immediate implementation of proper authentication checks for all Socket.IO event handlers within the LazyOwn framework, particularly in the lazyc2.py component. The codebase must be updated to validate and sanitize all incoming data before processing, implementing parameterized command execution instead of direct shell invocation. Additionally, access controls should be enforced at multiple layers including network-level firewall rules, authentication mechanisms, and application-level authorization checks. Organizations should conduct comprehensive security audits of their red-team tooling infrastructure and implement monitoring for unauthorized access attempts to critical C2 components. The fix implemented in version 0.2.154 addresses these fundamental security gaps by properly authenticating Socket.IO handlers and sanitizing input data before command execution, establishing a more secure foundation for red-team operations while maintaining the framework's core functionality.
