CVE-2006-1082 in phpArcadeScript
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in phpArcadeScript 2.0 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) the gamename parameter in tellafriend.php, (2) the login_status parameter in loginbox.php, (3) the submissionstatus parameter in index.php, the (4) cell_title_background_color and (5) browse_cat_name parameters in browse.php, the (6) gamefile parameter in displaygame.php, and (7) possibly other parameters in unspecified PHP scripts.

The vulnerability described in CVE-2006-1082 represents a critical cross-site scripting flaw affecting phpArcadeScript version 2.0 and earlier implementations. This vulnerability classifies under CWE-79 as a failure to sanitize user input, specifically manifesting as multiple injection points across various PHP scripts within the application. The flaw enables remote attackers to execute malicious scripts in the context of victim browsers, potentially leading to session hijacking, credential theft, or malicious content delivery. The affected parameters span across multiple files including tellafriend.php, loginbox.php, index.php, browse.php, and displaygame.php, indicating a widespread input validation failure throughout the application's codebase.
The technical exploitation of these vulnerabilities occurs when user-supplied data is directly incorporated into web page responses without proper sanitization or encoding. In tellafriend.php, the gamename parameter allows attackers to inject malicious scripts when sharing games, while loginbox.php's login_status parameter can be manipulated to execute code in authenticated user contexts. The index.php submissionstatus parameter creates another injection vector during game submission status display, while browse.php contains two additional vulnerable parameters: cell_title_background_color and browse_cat_name, which can be manipulated during category browsing operations. The displaygame.php gamefile parameter represents yet another avenue for malicious script injection during game file display operations.
The operational impact of this vulnerability extends beyond simple script execution as it fundamentally compromises the integrity of user sessions and data confidentiality. Attackers can leverage these XSS vectors to steal session cookies, redirect users to malicious sites, or inject persistent malicious content that affects all users interacting with the vulnerable application. The vulnerability's scope across multiple PHP files suggests a systemic lack of input validation and output encoding practices within the application architecture, potentially affecting user authentication mechanisms and data presentation layers. This weakness creates a persistent threat vector that remains active as long as the vulnerable version of phpArcadeScript remains deployed, with minimal effort required for exploitation.
Mitigation strategies for CVE-2006-1082 should prioritize immediate patching of the affected phpArcadeScript version to the latest available release. Organizations should implement comprehensive input validation and output encoding across all user-supplied parameters, following established security practices such as those outlined in the OWASP Top Ten and NIST guidelines for web application security. The implementation of Content Security Policy headers can provide additional defense-in-depth measures to prevent script execution from unauthorized sources. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities in other web applications, while proper parameter sanitization techniques including HTML entity encoding and input validation should be enforced throughout the application's codebase. The vulnerability demonstrates the critical importance of consistent security practices across all application components, as the failure to validate user input in one area can compromise the entire system's security posture.
