CVE-2006-3155 in Ultimate Estate
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Ultimate Auction 1.0 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) item parameter in (a) emailtofriend.pl or (b) violation.pl, (2) seller parameter in (c) vsoa.pl, (3) user parameter in (d) userask.pl or (e) leavefeed.pl, (4) itemnum parameter in userask.pl, (5) category parameter in (f) itemlist.pl, and the (6) query parameter in (g) search.pl.

The CVE-2006-3155 vulnerability represents a significant cross-site scripting flaw affecting the Ultimate Auction 1.0 software and earlier versions. This vulnerability manifests across multiple script files within the auction platform, creating widespread attack vectors that could allow remote threat actors to execute malicious scripts in the context of users' browsers. The flaw specifically resides in the handling of user-supplied input parameters without proper sanitization or validation, creating opportunities for attackers to inject arbitrary HTML and JavaScript code into the web application's response. These vulnerabilities are particularly dangerous because they affect core functionality scripts that handle user interactions, email communications, and search operations within the auction system.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding practices within the affected Perl scripts. Attackers can exploit the vulnerability by manipulating specific parameters in the URL requests to the targeted scripts, with each vulnerable parameter serving as a potential injection point for malicious payloads. The item parameter in emailtofriend.pl and violation.pl allows attackers to inject scripts when users receive emails containing malicious content. The seller parameter in vsoa.pl provides another vector for script injection, while the user parameter in userask.pl and leavefeed.pl creates opportunities for attackers to manipulate user interaction flows. Additional attack vectors include the itemnum parameter in userask.pl, category parameter in itemlist.pl, and query parameter in search.pl, all of which can be manipulated to deliver malicious scripts to unsuspecting users.
The operational impact of this vulnerability extends beyond simple script execution, as it can lead to session hijacking, credential theft, and unauthorized actions performed on behalf of authenticated users. When users visit pages containing malicious scripts, their browsers execute the injected code, potentially allowing attackers to access session cookies, steal login credentials, or redirect users to malicious websites. The vulnerability's widespread nature across multiple scripts means that a single attack vector could compromise various aspects of the auction platform's functionality, from user communications to search capabilities. This creates a cascading effect where a successful XSS attack could potentially expose sensitive user data, manipulate auction listings, or provide attackers with unauthorized access to the system's administrative functions.
From a cybersecurity perspective, this vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications. The attack patterns associated with this vulnerability map to multiple MITRE ATT&CK techniques including T1566 for phishing and T1059 for command and scripting interpreter usage. The vulnerability's exploitation requires minimal technical sophistication, making it particularly dangerous as it can be leveraged by attackers with basic web security knowledge. Organizations using the Ultimate Auction software should immediately implement input validation measures, output encoding, and proper parameter sanitization across all affected scripts. The recommended mitigation strategies include implementing proper HTML entity encoding for all user-supplied input, employing Content Security Policy headers, and conducting comprehensive code reviews to identify and remediate similar vulnerabilities in other application components. Regular security assessments and web application firewalls should also be deployed to detect and prevent exploitation attempts targeting these specific attack vectors.
