CVE-2024-11142 is a Cross-Site Request Forgery (CSRF) vulnerability identified in Gosoft Software's Proticaret E-Commerce platform, affecting 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 permits unauthorized commands to be transmitted from a user that the web application trusts, potentially enabling attackers to perform state-changing operations without the user's consent. The vulnerability is classified under CWE-352, which specifically relates to CSRF issues. The CVSS v3.1 base score is 5.4 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and low impact on confidentiality and integrity (C:L, I:L), with no impact on availability (A:N). The vendor has acknowledged the issue and is in the process of fixing it for version 4.05, with a full fix expected in version 6.0. No known exploits are currently reported in the wild. The vulnerability could allow attackers to perform unauthorized actions such as changing user settings, manipulating orders, or altering e-commerce configurations by exploiting the trust relationship between the user and the application, especially in administrative contexts. Since the attack requires the victim to be authenticated and the attacker to lure the victim into visiting a malicious site or clicking a crafted link, the risk is mitigated somewhat by user behavior but remains significant due to the lack of user interaction requirement and low attack complexity.

For European organizations using Proticaret E-Commerce, this vulnerability could lead to unauthorized transactions, manipulation of customer orders, or changes to e-commerce platform settings, potentially resulting in financial losses, reputational damage, and erosion of customer trust. Given that e-commerce platforms often handle sensitive customer data and payment information, even low confidentiality and integrity impacts can have cascading effects, including regulatory non-compliance under GDPR if personal data is compromised or mishandled. The vulnerability's exploitation could disrupt business operations by enabling attackers to alter pricing, inventory, or user permissions without detection. Since the vulnerability does not affect availability, denial-of-service is unlikely, but the integrity and confidentiality risks remain notable. Organizations with administrative users who have elevated privileges are particularly at risk, as attackers could leverage CSRF to escalate their control over the platform. The ongoing fix process suggests that organizations running affected versions should consider interim protective measures to reduce exposure. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits following public disclosure.

1. Immediate mitigation should include implementing CSRF tokens in all state-changing requests if not already present, ensuring that each request is validated for authenticity. 2. Enforce the use of the SameSite cookie attribute (preferably 'Strict' or 'Lax') to limit cookie transmission in cross-site contexts. 3. Require re-authentication or multi-factor authentication (MFA) for sensitive operations to add an additional layer of verification. 4. Monitor and restrict the use of privileged accounts, limiting their exposure to web browsing activities. 5. Employ Content Security Policy (CSP) headers to reduce the risk of malicious script execution that could facilitate CSRF attacks. 6. Educate users, especially administrators, about the risks of clicking on suspicious links or visiting untrusted websites while authenticated. 7. Regularly audit and update the Proticaret E-Commerce platform to the latest patched versions once available, prioritizing upgrades to v6.0 or later. 8. Implement web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns. 9. Review and harden session management policies to reduce session hijacking risks that could compound CSRF exploitation.
