CVE-2006-4747 in TextAds
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in IdevSpot TextAds allow remote attackers to inject arbitrary web script or HTML via (1) the id parameter in delete.php and (2) the error parameter in error.php.

The vulnerability identified as CVE-2006-4747 represents a critical cross-site scripting weakness within the IdevSpot TextAds application, a web-based advertising platform that facilitates the management and display of text advertisements. This vulnerability exposes the system to remote code execution risks through malicious injection of web scripts or HTML content, potentially compromising user sessions and data integrity. The flaw manifests in two distinct attack vectors within the application's file structure, specifically targeting the delete.php and error.php scripts that handle user input parameters without adequate sanitization or validation measures.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding practices within the IdevSpot TextAds codebase. Attackers can exploit the vulnerability by manipulating the id parameter in delete.php and the error parameter in error.php to inject malicious payloads that execute in the context of other users' browsers. This occurs because the application fails to properly sanitize user-supplied input before incorporating it into dynamic web page content, creating an environment where attacker-controlled data can be interpreted as executable code rather than mere text. The vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and represents a classic example of unsanitized input processing that violates fundamental web security principles.
The operational impact of this vulnerability extends beyond simple data theft or session hijacking, as it enables attackers to perform a range of malicious activities including credential theft, data manipulation, and potential lateral movement within compromised networks. Users who interact with the vulnerable application may unknowingly execute malicious scripts that can capture their session cookies, redirect them to phishing sites, or modify content displayed on the platform. The vulnerability affects the core functionality of the advertising platform, potentially allowing attackers to manipulate ad content, redirect traffic, or compromise the entire advertising ecosystem managed by the vulnerable system. This represents a significant risk to both the platform administrators and end-users who may be exposed to malicious advertisements or phishing attempts.
Mitigation strategies for CVE-2006-4747 should focus on implementing comprehensive input validation and output encoding mechanisms throughout the application. The most effective approach involves sanitizing all user-supplied parameters through proper escaping techniques before incorporating them into web page content, particularly for dynamic elements that may be rendered in browser contexts. Organizations should implement Content Security Policy headers to limit script execution and prevent unauthorized code injection, while also ensuring that all user inputs undergo rigorous validation before processing. The remediation process requires immediate patching of the vulnerable code in delete.php and error.php files, with developers implementing proper parameter validation and output encoding to prevent the injection of malicious content. Security measures should also include regular code reviews and vulnerability assessments to identify similar issues in other parts of the application, aligning with ATT&CK technique T1566 for social engineering and T1059 for command and scripting interpreters. Additionally, implementing web application firewalls and monitoring systems can provide additional layers of protection against exploitation attempts, while user education regarding suspicious website behavior remains crucial for overall security posture improvement.
