CVE-2006-7072 in GeoClassifieds Enterprise
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in GeoClassifieds Enterprise 2.0.5.2 and earlier allows remote attackers to inject arbitrary web script and HTML via the (1) b[username] and (2) c parameters to (a) index.php, the b[username] parameter to (b) admin/index.php, and (3) c[phone] parameter to register.php.

The CVE-2006-7072 vulnerability represents a critical cross-site scripting flaw in GeoClassifieds Enterprise 2.0.5.2 and earlier versions, exposing web applications to persistent security risks. This vulnerability specifically targets multiple input parameters across different application endpoints, creating multiple attack vectors that threat actors can exploit to execute malicious code within user browsers. The flaw resides in the application's insufficient input validation and output encoding mechanisms, allowing attackers to inject arbitrary web scripts and HTML content that gets executed in the context of other users' sessions.
The technical implementation of this vulnerability occurs through three distinct parameter injection points that collectively demonstrate poor security design practices. The first vector involves the b[username] parameter in the index.php file, while the second targets the c parameter in the same file, and the third vulnerability exists in the c[phone] parameter of register.php. Additionally, the b[username] parameter in admin/index.php presents another attack surface that threat actors can leverage for privilege escalation or administrative access manipulation. These parameters are processed without proper sanitization, enabling attackers to inject malicious payloads that bypass standard security controls.
The operational impact of this vulnerability extends beyond simple script injection, as it can facilitate session hijacking, credential theft, and unauthorized administrative actions. When users interact with compromised pages, their browsers execute the injected scripts, potentially leading to complete account compromise or data exfiltration. The vulnerability affects both frontend and administrative interfaces, creating a comprehensive attack surface that can be exploited by attackers with minimal technical expertise. This type of vulnerability directly violates security principles outlined in the OWASP Top Ten and aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications.
Mitigation strategies for CVE-2006-7072 require immediate implementation of input validation and output encoding controls across all affected parameters. Organizations should implement strict sanitization of user inputs through parameterized queries and HTML escaping mechanisms to prevent script injection. The application code must be updated to properly validate and sanitize all incoming data before processing, with particular attention to the identified parameter names. Security patches should be applied immediately to upgrade to versions beyond 2.0.5.2, as this vulnerability was likely addressed in subsequent releases. Network-based protections such as web application firewalls can provide additional defense-in-depth measures, though they should not be considered replacements for proper code-level fixes. The vulnerability demonstrates the importance of implementing secure coding practices and regular security assessments to identify and remediate similar issues in web applications. This flaw also aligns with ATT&CK technique T1566, which covers the exploitation of vulnerabilities in web applications to gain unauthorized access to systems and data.
