CVE-2017-14404 in EyesOfNetwork Web Interface
Summary
by MITRE
The EyesOfNetwork web interface (aka eonweb) 5.1-0 allows local file inclusion via the tool_list parameter (aka the url_tool variable) to module/tool_all/select_tool.php, as demonstrated by a tool_list=php://filter/ substring.

The CVE-2017-14404 vulnerability represents a critical local file inclusion flaw within the EyesOfNetwork web interface version 5.1-0, specifically affecting the module/tool_all/select_tool.php component. This vulnerability arises from insufficient input validation and sanitization of the tool_list parameter, which is processed through the url_tool variable, creating an exploitable path for attackers to manipulate file inclusion operations. The vulnerability is particularly concerning as it allows attackers to leverage PHP's stream wrapper functionality, specifically the php://filter/ substring, to execute arbitrary file inclusion attacks against the web application.
The technical implementation of this vulnerability stems from the application's failure to properly validate or sanitize user-supplied input before incorporating it into file inclusion operations. When the tool_list parameter is passed to the url_tool variable, the application directly uses this input without adequate sanitization, enabling attackers to inject malicious payloads that can traverse the file system and include arbitrary files. The php://filter/ stream wrapper functionality provides attackers with a mechanism to read or include files that would otherwise be restricted, effectively bypassing normal file access controls and enabling unauthorized access to sensitive system resources.
This vulnerability creates significant operational impact for organizations using EyesOfNetwork, as it can be exploited to gain unauthorized access to server files, potentially leading to complete system compromise. Attackers can leverage this flaw to read sensitive configuration files, access database credentials, or even execute arbitrary code on the affected server. The local file inclusion nature of this vulnerability means that successful exploitation can provide attackers with access to the underlying operating system, potentially enabling privilege escalation and persistent access to the network infrastructure. The impact extends beyond immediate data exposure to include potential lateral movement within the network and establishment of backdoors for continued access.
Organizations should implement immediate mitigations including input validation and sanitization of all user-supplied parameters, particularly those used in file inclusion operations. The implementation of proper access controls and the removal of unnecessary file inclusion capabilities can significantly reduce the attack surface. Additionally, applying the latest security patches from EyesOfNetwork vendors and implementing web application firewalls can provide additional protection layers. The vulnerability aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, and represents a classic example of insecure direct object reference that can be exploited through path traversal techniques. From an ATT&CK framework perspective, this vulnerability maps to T1059 for command and script injection, and T1083 for file and directory discovery, representing a critical entry point for attackers seeking to establish persistent access and escalate privileges within compromised environments.
