CVE-2006-3613 in Ezwaiter Online
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Chamberland Technology ezWaiter 3.0 Online and possibly Enterprise Software (aka enterprise edition) allow remote attackers to inject arbitrary web script or HTML via the (1) itemfor (aka "Who is this item for?") and (2) special (aka "Special Instructions") parameters to item.php, which is accessed from showorder.php, or (3) unspecified parameters to the login form at login.php.

The vulnerability described in CVE-2006-3613 represents a critical cross-site scripting weakness affecting Chamberland Technology ezWaiter 3.0 Online and Enterprise Software versions. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, which is one of the most prevalent and dangerous web application security flaws identified in the CWE database. The flaw exists in the web application's handling of user input parameters, specifically within the item.php and login.php scripts that process customer order information and authentication requests.
The technical implementation of this vulnerability occurs through three distinct attack vectors that exploit the application's insufficient input validation and output encoding mechanisms. The first vector targets the itemfor parameter, which is used to capture information about who a particular menu item is designated for, while the second vector exploits the special parameter that collects special instructions for orders. Both of these parameters are processed by item.php, which is invoked through showorder.php, creating a pathway for malicious script injection. The third vector involves unspecified parameters within the login.php form, indicating that the vulnerability may extend beyond the documented parameters to other form fields. These attack vectors demonstrate how the application fails to properly sanitize user-supplied data before incorporating it into dynamic web page content, creating opportunities for attackers to inject malicious javascript code.
The operational impact of this vulnerability is severe as it allows remote attackers to execute arbitrary web scripts in the context of the victim's browser session. This capability enables attackers to perform a wide range of malicious activities including session hijacking, credential theft, defacement of the web application, and redirection to malicious sites. The vulnerability affects both the online and enterprise editions of the software, suggesting a widespread impact across different deployment scenarios. Attackers could potentially exploit these vulnerabilities to steal sensitive customer information, manipulate order processing, or gain unauthorized access to the system. The fact that the vulnerability exists in both order processing and authentication components creates a particularly dangerous attack surface where attackers could compromise user sessions and potentially escalate privileges.
Mitigation strategies for this vulnerability should focus on implementing comprehensive input validation and output encoding practices across all user-facing application components. The primary defense mechanism involves sanitizing all user input parameters before they are processed or displayed in web pages, which aligns with the recommendations in the OWASP Top Ten security framework and the ATT&CK technique T1203 for credential access through web application vulnerabilities. Organizations should implement proper HTML encoding for all dynamic content, utilize secure coding practices, and deploy web application firewalls to filter malicious payloads. Additionally, regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other application components. The remediation process must include updating the software to a patched version if available, or implementing proper input sanitization measures that ensure all user-supplied data is properly validated and escaped before being rendered in web browser contexts. This vulnerability highlights the critical importance of defense-in-depth security measures and proper secure coding practices in preventing persistent cross-site scripting attacks.
