CVE-2006-2810 in vCard
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Belchior Foundry vCard 2.9 allow remote attackers to inject arbitrary web script or HTML via the page parameter in (1) toprated.php and (2) newcards.php. NOTE: the card_id vector is already covered by CVE-2006-1230.

The vulnerability described in CVE-2006-2810 represents a critical cross-site scripting flaw affecting the Belchior Foundry vCard 2.9 web application. This vulnerability specifically targets two distinct PHP scripts within the application framework namely toprated.php and newcards.php which are designed to handle user interactions and display card-related content. The flaw stems from insufficient input validation and output encoding mechanisms that fail to properly sanitize user-supplied data before incorporating it into dynamically generated web pages. Attackers can exploit this weakness by manipulating the page parameter through HTTP requests to inject malicious JavaScript code or HTML content directly into the application's response stream.
The technical nature of this vulnerability aligns with CWE-79 which categorizes cross-site scripting as a code injection flaw where untrusted data is incorporated into web pages without proper validation or sanitization. The attack vector specifically leverages the page parameter which serves as an entry point for malicious input to be processed by the vulnerable scripts. When the application processes this parameter without adequate filtering, it allows attackers to execute arbitrary scripts in the context of other users' browsers who view the affected pages. This creates a persistent threat where malicious code can be stored and executed whenever legitimate users access the compromised pages.
The operational impact of this vulnerability extends beyond simple data theft or defacement as it provides attackers with the capability to establish persistent access to user sessions and potentially escalate privileges within the application environment. Users who view pages containing malicious code could have their browser sessions hijacked, sensitive information stolen, or their browsers redirected to malicious sites. The vulnerability affects the core functionality of the vCard application which manages contact information and card displays, making it particularly dangerous for organizations relying on this tool for business communications. The fact that this vulnerability exists in multiple scripts increases the attack surface and reduces the effectiveness of any single mitigation strategy.
Mitigation efforts should focus on implementing comprehensive input validation and output encoding across all user-facing parameters within the application. The most effective immediate fix involves sanitizing the page parameter in both toprated.php and newcards.php scripts to remove or encode potentially dangerous characters before processing user input. Organizations should also consider implementing Content Security Policy headers to limit the execution of unauthorized scripts and establish proper parameter validation routines that reject malformed input. Additionally, the application should be updated to a newer version that addresses this vulnerability as the original vCard 2.9 version appears to be outdated and likely contains other unpatched security flaws. From an ATT&CK framework perspective, this vulnerability maps to techniques involving code injection and session hijacking, making it a significant threat that requires immediate attention to prevent potential compromise of user data and system integrity.
