CVE-2008-6945 in Interchange
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Interchange 5.7 before 5.7.1, 5.6 before 5.6.1, and 5.4 before 5.4.3 allow remote attackers to inject arbitrary web script or HTML via (1) the mv_order_item CGI variable parameter in Core, (2) the country-select widget, or (3) possibly the value specifier when used in the UserTag feature.

The vulnerability identified as CVE-2008-6945 represents a critical cross-site scripting weakness affecting the Interchange e-commerce platform across multiple versions including 5.7 before 5.7.1, 5.6 before 5.6.1, and 5.4 before 5.4.3. This vulnerability exposes the platform to remote code execution through malicious script injection, creating significant security risks for online commerce operations that rely on the affected software components. The flaw specifically impacts three distinct attack vectors within the Interchange framework, making it particularly dangerous as it provides multiple pathways for exploitation.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding mechanisms within the Interchange platform's core processing modules. The first attack vector involves the mv_order_item CGI variable parameter in Core functionality, where user-supplied data is not properly sanitized before being processed and returned to web clients. The second vector targets the country-select widget, indicating that even standard user interface components contain inadequate security controls for handling potentially malicious input. The third vector relates to the value specifier within the UserTag feature, which suggests that the platform's extensible tagging system also suffers from insufficient sanitization of user-provided content. These vulnerabilities align with CWE-79, which specifically addresses cross-site scripting flaws in web applications.
The operational impact of CVE-2008-6945 extends beyond simple data theft or defacement, as successful exploitation could enable attackers to execute arbitrary scripts in the context of victim browsers. This capability allows threat actors to perform session hijacking, steal sensitive customer information, modify transaction data, or redirect users to malicious websites. The vulnerability affects e-commerce operations by potentially compromising customer trust, leading to financial losses, regulatory penalties, and damage to brand reputation. Attackers could leverage these XSS flaws to access customer payment information, personal details, or administrative functions within the Interchange platform.
Mitigation strategies for this vulnerability require immediate patching of affected Interchange versions to 5.7.1, 5.6.1, and 5.4.3 respectively, as these releases contain the necessary security fixes. Organizations should implement comprehensive input validation mechanisms that sanitize all user-supplied data before processing, particularly for CGI parameters and widget inputs. The implementation of Content Security Policy (CSP) headers can provide additional protection layers against script execution. Security teams should also conduct thorough code reviews of custom UserTag implementations and ensure that all user interface components properly encode output data. From an ATT&CK framework perspective, this vulnerability maps to T1566.001 (Phishing with Malicious Attachments) and T1059.001 (Command and Scripting Interpreter) as attackers could use the XSS capability to establish persistent access or execute malicious commands within the victim environment.
