CVE-2008-3150 in Atomic Edition
Summary
by MITRE
Directory traversal vulnerability in index.php in Neutrino Atomic Edition 0.8.4 allows remote attackers to read and modify files, as demonstrated by manipulating data/sess.php in (1) usb and (2) del_pag actions. NOTE: this can be leveraged for code execution by performing an upload that bypasses the intended access restrictions that were implemented in sess.php.

The CVE-2008-3150 vulnerability represents a critical directory traversal flaw in the Neutrino Atomic Edition 0.8.4 web application framework that fundamentally compromises the application's file system security boundaries. This vulnerability exists within the index.php file and specifically targets the data/sess.php component through two distinct action parameters: usb and del_pag. The flaw allows remote attackers to bypass intended access controls and manipulate files outside the application's designated directory structure, creating a severe security breach that extends far beyond typical file access restrictions.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the application's parameter handling mechanisms. When attackers manipulate the usb and del_pag action parameters, the application fails to properly validate or sanitize user-supplied input before processing file operations. This allows malicious actors to inject directory traversal sequences such as ../ or ..\ that cause the application to navigate outside its intended directory structure. The vulnerability specifically affects the data/sess.php file which serves as a session management component, making it particularly dangerous as it can compromise user sessions and potentially lead to unauthorized access to sensitive application data. This flaw aligns with CWE-22 Directory Traversal vulnerability classification, which encompasses improper input validation that allows attackers to access files and directories outside the intended scope.
The operational impact of this vulnerability extends beyond simple file reading capabilities to include full file modification and potential code execution. Attackers can leverage the directory traversal to upload malicious files that bypass the access restrictions implemented in sess.php, effectively creating a backdoor within the application. This capability transforms a simple directory traversal vulnerability into a full exploitation vector that can lead to complete system compromise. The vulnerability's potential for code execution makes it particularly dangerous in web application environments where attackers can leverage the uploaded files to establish persistent access or execute arbitrary commands on the target system. This type of vulnerability can be mapped to ATT&CK technique T1059 Command and Scripting Interpreter, as it enables adversaries to execute code through the compromised application.
The security implications of this vulnerability are severe as it undermines the fundamental security model of the application, allowing unauthorized access to sensitive data and system resources. The fact that the vulnerability can be exploited for code execution through file upload bypass mechanisms makes it particularly concerning for web applications that handle sensitive user data or business-critical information. Organizations running Neutrino Atomic Edition 0.8.4 are at significant risk of data breaches, unauthorized system access, and potential complete compromise of their web infrastructure. The vulnerability demonstrates a critical failure in input validation and access control implementation, highlighting the importance of proper security coding practices and comprehensive security testing. Remediation efforts should focus on implementing strict input validation, proper parameter sanitization, and robust access control mechanisms that prevent directory traversal attacks and ensure that all file operations occur within intended boundaries.
