CVE-2023-5112 in Os Commerce
Summary
by MITRE • 10/25/2023
Os Commerce is currently susceptible to a Cross-Site Scripting (XSS) vulnerability. This vulnerability allows attackers to inject JS through the "specials_type_name[1]" parameter,
potentially leading to unauthorized execution of scripts within a user's web browser.

The vulnerability identified as CVE-2023-5112 represents a critical cross-site scripting flaw within the Os Commerce platform that exposes end users to significant security risks. This weakness resides in the application's handling of user input through the "specials_type_name[1]" parameter, which fails to properly sanitize or validate data before processing. The vulnerability falls under the CWE-79 category of Cross-Site Scripting, a well-documented and prevalent weakness that enables attackers to inject malicious scripts into web applications. The specific parameter mentioned in the vulnerability description indicates that the flaw occurs within the administrative or special products configuration functionality of the e-commerce platform, where users can define special offers or promotions.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious JavaScript code and submits it through the vulnerable parameter. When the application processes this input without proper sanitization, the malicious script becomes embedded within the application's response and is subsequently executed within the context of a victim's browser. This type of attack follows the standard XSS attack pattern where the malicious payload is stored or reflected in the application's response, allowing the attacker to execute unauthorized scripts. The vulnerability's impact extends beyond simple script execution as it can potentially enable session hijacking, credential theft, or redirection to malicious websites. The attack vector aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments or links, and T1059.007 for command and control through script-based payloads.
The operational consequences of this vulnerability are severe for Os Commerce deployments as it creates a persistent threat vector that can be exploited by attackers with minimal technical expertise. Organizations using this e-commerce platform face potential data breaches, unauthorized access to customer information, and possible compromise of the entire web application. The vulnerability's presence in the administrative interface suggests that attackers could gain elevated privileges or manipulate product configurations, potentially leading to financial loss or reputational damage. The reflected nature of the XSS vulnerability means that the attack can be delivered through various vectors including email links, social media posts, or compromised web pages that redirect users to the vulnerable application. This makes the attack surface particularly broad and difficult to control without proper input validation and output encoding measures.
Mitigation strategies for CVE-2023-5112 must focus on implementing robust input validation and output encoding mechanisms throughout the Os Commerce application. The primary defense should involve sanitizing all user inputs, particularly those used in dynamic content generation, through proper encoding techniques such as HTML entity encoding and JavaScript escaping. Implementing Content Security Policy (CSP) headers can provide additional protection by restricting script execution within the application's context. Organizations should also consider implementing Web Application Firewall (WAF) rules specifically designed to detect and block XSS attack patterns targeting the affected parameter. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities within the application's codebase. The fix should align with industry best practices for XSS prevention as outlined in OWASP Top 10 and the CWE guidelines for secure coding practices, particularly focusing on the proper handling of user-supplied data in web applications. Additionally, implementing proper access controls and input validation for administrative functions can significantly reduce the risk of exploitation.
