CVE-2024-58304 identifies a stored cross-site scripting (XSS) vulnerability in SPA-CART CMS version 1.9.0.3, specifically within the 'descr' parameter of the product description field. This vulnerability arises from improper neutralization of input during web page generation (CWE-79), allowing authenticated administrators to inject arbitrary JavaScript code that is stored and subsequently executed in the browsers of other administrative users viewing the product details. The attack vector requires authentication but no elevated privileges beyond admin access, and no additional user interaction beyond accessing the affected page. The vulnerability can be exploited to perform malicious actions such as session hijacking, stealing credentials, or executing unauthorized commands within the CMS context. The CVSS 4.0 base score is 5.3, reflecting medium severity due to the need for authentication and limited scope of impact. No known public exploits have been reported yet. The vulnerability highlights a failure in input validation and output encoding in the CMS's product editing functionality, which should sanitize or encode user inputs to prevent script injection. SPA-CART CMS is a content management system used for e-commerce platforms, and this vulnerability could compromise administrative control over the system, potentially leading to broader compromise of e-commerce operations and customer data if exploited.

For European organizations, this vulnerability poses a risk primarily to the integrity and confidentiality of administrative sessions within SPA-CART CMS environments. Successful exploitation could allow attackers to hijack admin sessions, manipulate product data, or escalate privileges indirectly by leveraging stolen credentials or session tokens. This can disrupt e-commerce operations, damage brand reputation, and lead to data breaches involving customer or transactional information. Given the vulnerability requires authenticated access, insider threats or compromised admin credentials increase risk. The impact is amplified in organizations with multiple administrators or where SPA-CART CMS is integrated with other business-critical systems. Additionally, regulatory frameworks such as GDPR impose strict requirements on protecting personal data, and exploitation leading to data exposure could result in significant legal and financial penalties. The absence of known exploits provides a window for proactive mitigation, but the medium severity score indicates that timely action is necessary to prevent potential attacks.

To mitigate CVE-2024-58304, organizations should implement the following specific measures: 1) Apply any available patches or updates from SPA-CART CMS vendors as soon as they are released. 2) If patches are unavailable, implement strict input validation and output encoding on the 'descr' parameter to neutralize script injection attempts. 3) Restrict administrative access to trusted personnel and enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of credential compromise. 4) Conduct regular security audits and code reviews focusing on input handling in the CMS. 5) Monitor administrative activity logs for unusual behavior indicative of exploitation attempts. 6) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in admin browsers. 7) Educate administrators about the risks of XSS and safe handling of product descriptions. 8) Isolate the CMS environment from other critical systems to contain potential breaches. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and administrative context of the SPA-CART CMS.
