CVE-2006-7173 in PHP-Stats
Summary
by MITRE
Direct static code injection vulnerability in admin.php in PHP-Stats 0.1.9.1b and earlier allows remote attackers to execute arbitrary PHP code via a crafted option_new[report_w_day] parameter in a preferenze action, which can be later accessed via option/php-stats-options.php.

The vulnerability identified as CVE-2006-7173 represents a critical direct static code injection flaw within the PHP-Stats 0.1.9.1b and earlier versions. This vulnerability exists in the administrative component of the software, specifically within the admin.php file that handles user preferences and reporting configurations. The flaw stems from inadequate input validation and sanitization mechanisms that fail to properly process user-supplied data before incorporating it into the application's execution flow.
The technical exploitation of this vulnerability occurs through manipulation of the option_new[report_w_day] parameter during a preferenze action. When an attacker crafts malicious input for this parameter and submits it through the web interface, the application directly incorporates this unvalidated data into its PHP execution context without proper sanitization. This allows attackers to inject arbitrary PHP code that gets executed within the application's server environment, effectively granting remote code execution capabilities. The vulnerability is classified as a direct static code injection because the malicious code is injected directly into the application's code execution path rather than being executed through indirect means.
The operational impact of this vulnerability is severe and multifaceted. Remote attackers can leverage this flaw to execute arbitrary commands on the affected server, potentially leading to complete system compromise. The vulnerability affects the administrative interface of PHP-Stats, which typically requires elevated privileges to access, but the code injection allows attackers to bypass authentication mechanisms and directly execute malicious code. This creates a significant risk for web applications that rely on PHP-Stats for analytics and reporting, as the compromise of the administrative interface can lead to data theft, service disruption, and further lateral movement within the network infrastructure. The vulnerability affects systems where PHP-Stats is deployed, particularly those with default or weak security configurations.
Security mitigations for this vulnerability should focus on immediate patching of the affected software version to PHP-Stats 0.1.9.2 or later, which contains the necessary input validation fixes. Additionally, implementing proper parameter validation and sanitization within the application code is essential to prevent similar vulnerabilities. The solution aligns with CWE-94, which specifically addresses "Improper Control of Generation of Code ('Code Injection')" and follows ATT&CK technique T1059.007 for "Command and Scripting Interpreter: PowerShell" and T1059.006 for "Command and Scripting Interpreter: Python" in cases where attackers might use other scripting languages to exploit similar injection vectors. Organizations should also implement web application firewalls and input validation rules to detect and block malicious payloads targeting such injection vulnerabilities. The remediation process must include comprehensive security testing to ensure that all user inputs are properly sanitized and that no similar code injection vulnerabilities exist within the application's codebase.
