CVE-2012-6458 in SilverStripe
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in the SilverStripe e-commerce module 3.0 for SilverStripe CMS allow remote attackers to inject arbitrary web script or HTML via the (1) FirstName, (2) Surname, or (3) Email parameter to code/forms/OrderFormAddress.php; or the (4) FirstName or (5) Surname parameter to code/forms/ShopAccountForm.php.

The vulnerability identified as CVE-2012-6458 represents a critical cross-site scripting flaw within the SilverStripe e-commerce module version 3.0, specifically affecting the SilverStripe Content Management System. This security weakness stems from inadequate input validation and output sanitization mechanisms within the e-commerce module's form handling components. The vulnerability impacts multiple user-facing forms that process customer information during the checkout and account creation processes, creating a significant attack surface for malicious actors seeking to exploit web application security flaws.
The technical implementation of this vulnerability occurs in two primary locations within the SilverStripe e-commerce module's codebase. The first exploitation vector targets the OrderFormAddress.php file where the FirstName, Surname, and Email parameters fail to properly sanitize user input before rendering in web pages. The second vector affects the ShopAccountForm.php file where the FirstName and Surname parameters present similar sanitization failures. These flaws align with CWE-79, which specifically addresses cross-site scripting vulnerabilities resulting from insufficient input validation and output encoding. The vulnerability demonstrates a classic case of improper data sanitization where user-supplied data flows directly into HTML output without appropriate encoding or filtering mechanisms.
The operational impact of CVE-2012-6458 extends beyond simple data theft or defacement, creating potential for severe downstream consequences within e-commerce environments. Attackers can leverage these vulnerabilities to execute malicious scripts in the context of authenticated user sessions, potentially leading to account takeover, data exfiltration, or the redirection of users to malicious sites. The attack surface includes customer personal information including names and email addresses, which could be harvested for identity theft or used as part of larger phishing campaigns. This vulnerability particularly affects e-commerce platforms where user trust and data security are paramount, as the compromised forms handle sensitive customer information during transaction processes.
Security professionals should recognize this vulnerability as a prime example of how web application frameworks can introduce security risks through insufficient input validation at critical user interaction points. The attack pattern aligns with ATT&CK technique T1566, specifically targeting the credential access and data extraction phases through web application exploitation. Organizations running SilverStripe e-commerce modules should prioritize immediate patching of this vulnerability, as the attack surface remains significant even in environments with proper network segmentation. Recommended mitigations include implementing comprehensive input validation, output encoding, and content security policies to prevent script execution in user-controllable fields. The vulnerability also highlights the importance of regular security assessments and the implementation of web application firewalls to detect and prevent exploitation attempts targeting form-based input fields.
