CVE-2006-6929 in Rapid Classified
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Rapid Classified 3.1 allow remote attackers to inject arbitrary web script or HTML via the (1) id parameter to (a) reply.asp or (b) view_print.asp, the (2) SH1 parameter to (c) search.asp, the (3) name parameter to reply.asp, or the (4) dosearch parameter to (d) advsearch.asp.

The CVE-2006-6929 vulnerability represents a critical cross-site scripting flaw discovered in Rapid Classified 3.1, a web application designed for classified advertising services. This vulnerability exposes the application to remote code execution through malicious script injection, potentially compromising user sessions and data integrity. The flaw manifests across multiple endpoints including reply.asp, view_print.asp, search.asp, and advsearch.asp, demonstrating a widespread vulnerability in input validation mechanisms. The vulnerability classification aligns with CWE-79, which specifically addresses cross-site scripting vulnerabilities in web applications, making it a prime target for attackers seeking to exploit user trust and manipulate web application behavior.
The technical implementation of this vulnerability stems from inadequate sanitization of user-supplied input parameters within the Rapid Classified application. Attackers can exploit four distinct parameter injection points to execute malicious scripts in victim browsers. The id parameter in reply.asp and view_print.asp allows injection of arbitrary HTML content through numeric identifiers, while the SH1 parameter in search.asp accepts malicious input that gets reflected back to users. Additionally, the name parameter in reply.asp and dosearch parameter in advsearch.asp provide further attack vectors for XSS exploitation. These injection points demonstrate poor input validation practices where user data is directly incorporated into web responses without proper encoding or sanitization.
The operational impact of this vulnerability extends beyond simple script execution, creating potential for session hijacking, credential theft, and data manipulation within the classified advertising platform. When victims browse pages containing maliciously injected scripts, their browsers execute the attacker-controlled code, potentially leading to unauthorized access to classified advertisements, user account compromise, or even complete system infiltration. The vulnerability affects the core functionality of the classified advertising system, as attackers can manipulate search results, alter display content, and potentially redirect users to malicious sites. This represents a significant risk to both the application's integrity and user privacy, particularly in environments where classified information is sensitive and requires protection.
Security mitigation strategies for CVE-2006-6929 should focus on implementing comprehensive input validation and output encoding mechanisms throughout the application. The most effective remediation involves sanitizing all user-supplied parameters before they are processed or displayed in web responses, utilizing proper HTML encoding techniques to prevent script execution. Organizations should implement strict parameter validation rules that reject or sanitize input containing potentially dangerous characters such as angle brackets, quotes, and script tags. Additionally, the application should employ Content Security Policy headers to prevent unauthorized script execution, and regular security testing should be conducted to identify similar vulnerabilities in other parameters or endpoints. The remediation approach aligns with ATT&CK technique T1203, which addresses the exploitation of input validation flaws in web applications, emphasizing the need for robust defensive measures against such persistent security threats.
