CVE-2017-14118 in EyesOfNetwork Web Interface
Summary
by MITRE
In the EyesOfNetwork web interface (aka eonweb) 5.1-0, module\tool_all\tools\interface.php does not properly restrict exec calls, which allows remote attackers to execute arbitrary commands via shell metacharacters in the host_list parameter to module/tool_all/select_tool.php.

The vulnerability identified as CVE-2017-14118 resides within the EyesOfNetwork web interface version 5.1-0, specifically within the ool_all module located in tools/interface.php. This critical security flaw represents a command injection vulnerability that arises from inadequate input validation and sanitization within the web application's execution handling mechanisms. The vulnerability manifests when the application fails to properly restrict exec calls, creating a pathway for remote attackers to manipulate system commands through maliciously crafted input.
The technical implementation of this vulnerability occurs through the host_list parameter in the module/tool_all/select_tool.php endpoint. When an attacker submits shell metacharacters within this parameter, the application processes these inputs without sufficient sanitization, allowing the malicious commands to be executed with the privileges of the web application. This represents a classic command injection vulnerability where user-controllable input directly influences system command execution, bypassing normal security controls and access restrictions.
The operational impact of this vulnerability extends beyond simple remote code execution, as it provides attackers with the capability to perform arbitrary command execution on the affected system. This can lead to complete system compromise, data exfiltration, privilege escalation, and potential lateral movement within the network. The vulnerability affects the EyesOfNetwork web interface, which is designed for network monitoring and security management, making it particularly dangerous as attackers could gain access to critical network security infrastructure. The remote nature of the attack means that exploitation can occur from any location without requiring physical access to the system.
From a cybersecurity framework perspective, this vulnerability maps directly to CWE-77 and CWE-88 within the Common Weakness Enumeration catalog, representing command injection and improper neutralization of special elements used in argument lists respectively. The attack pattern aligns with ATT&CK technique T1059.001 for command and scripting interpreter, specifically focusing on the execution of malicious commands through web interfaces. Organizations utilizing EyesOfNetwork version 5.1-0 should immediately implement mitigations including input validation, parameter sanitization, and the implementation of proper access controls to prevent unauthorized command execution.
The remediation approach requires immediate patching of the affected software version, implementing strict input validation mechanisms, and applying proper output encoding to prevent shell metacharacter interpretation. Security administrators should also consider implementing network segmentation, web application firewalls, and monitoring for suspicious command execution patterns. The vulnerability demonstrates the critical importance of proper input sanitization in web applications and highlights the necessity of following secure coding practices to prevent command injection attacks that can lead to complete system compromise and unauthorized access to sensitive network infrastructure.
