CVE-2024-11142 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability affecting Gosoft Software's Proticaret E-Commerce platform, specifically versions prior to v6.0, including version 4.05. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting unwanted actions on a web application in which they are currently authenticated. In this case, the vulnerability enables attackers to perform unauthorized state-changing operations on the Proticaret E-Commerce platform without the user's consent or knowledge. Given the nature of e-commerce platforms, such unauthorized actions could include modifying product listings, changing prices, altering user account details, or manipulating order information. The CVSS v3.1 base score of 8.8 reflects the critical impact on confidentiality, integrity, and availability, with an attack vector over the network, low attack complexity, no privileges required, but requiring user interaction. The vulnerability is exploitable remotely without authentication, but requires the victim to interact with a maliciously crafted request, such as clicking a link or visiting a malicious website while logged into the affected platform. The vendor has acknowledged the issue and is in the process of fixing it for version 4.05, but no patches are currently available. No known exploits are reported in the wild yet. The vulnerability is classified under CWE-352, which is a common and well-understood web security issue related to insufficient anti-CSRF protections such as missing or ineffective CSRF tokens or validation mechanisms.

For European organizations using Proticaret E-Commerce, this vulnerability poses significant risks. Attackers could exploit CSRF to perform unauthorized transactions, manipulate product or pricing data, or compromise user accounts, leading to financial losses, reputational damage, and potential regulatory non-compliance under GDPR due to unauthorized data manipulation or exposure. The integrity and availability of the e-commerce platform could be severely impacted, disrupting business operations and customer trust. Since the vulnerability does not require authentication, attackers can target any user currently logged into the platform, increasing the attack surface. This is particularly concerning for SMEs and online retailers in Europe relying on Proticaret E-Commerce for their sales channels. Additionally, the lack of an available patch means organizations must rely on interim mitigations, increasing operational risk until a fix is released.

European organizations should implement immediate compensating controls to mitigate the risk of CSRF exploitation. These include: 1) Enforcing strict Content Security Policy (CSP) headers to reduce the risk of malicious cross-site requests; 2) Implementing SameSite cookie attributes (preferably 'Strict' or 'Lax') to limit cookie transmission in cross-origin requests; 3) Monitoring and restricting referrer headers to detect suspicious requests; 4) Educating users to avoid clicking on untrusted links while logged into the platform; 5) Applying web application firewalls (WAF) with custom rules to detect and block CSRF attack patterns; 6) Conducting thorough security reviews of all state-changing endpoints to ensure they require valid anti-CSRF tokens or equivalent protections; 7) Isolating administrative interfaces and enforcing multi-factor authentication to reduce risk exposure; 8) Preparing for rapid patch deployment once the vendor releases an official fix. Organizations should also audit logs for unusual activity indicative of CSRF exploitation attempts and consider temporary disabling or restricting high-risk functionalities until patched.
