CVE-2025-13004 identifies a medium-severity authorization bypass vulnerability in the Farktor Software E-Commerce Package, tracked under CWE-639 (Authorization Bypass Through User-Controlled Key). This vulnerability arises because the software improperly validates or restricts user-controlled keys or variables, allowing authenticated users with limited privileges to manipulate these keys to perform unauthorized actions. The flaw compromises the integrity of the system by enabling privilege escalation or unauthorized modifications within the e-commerce platform, potentially affecting order processing, user data, or transaction records. The vulnerability requires an attacker to have some level of authenticated access and user interaction, which limits remote exploitation but does not eliminate risk, especially from insider threats or compromised accounts. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:L) indicates network attack vector, low attack complexity, privileges required, user interaction required, unchanged scope, no confidentiality impact, high integrity impact, and low availability impact. No patches or known exploits are currently available, suggesting organizations must rely on compensating controls until an official fix is released. The vulnerability affects all versions up to 27112025, with no specific patch links provided. Given the critical role of e-commerce platforms in business operations, exploitation could disrupt transaction integrity and customer trust.

For European organizations, exploitation of this vulnerability could lead to unauthorized modification of e-commerce transactions, order details, or user permissions, undermining data integrity and potentially causing financial discrepancies or reputational damage. Although confidentiality is not directly impacted, the integrity breach can facilitate fraud or unauthorized purchases. Availability impact is low but could occur if the system detects anomalies and triggers protective shutdowns. The requirement for authenticated access and user interaction reduces the risk of mass exploitation but increases the threat from insider attacks or compromised user accounts. European companies with significant online retail operations using the Farktor E-Commerce Package may face operational disruptions and compliance challenges, especially under GDPR regulations concerning data integrity and security. The lack of patches necessitates immediate risk management and monitoring to prevent exploitation.

1. Implement strict input validation and sanitization for all user-controlled keys or variables to prevent manipulation. 2. Enforce the principle of least privilege rigorously, ensuring users have only the minimum necessary permissions. 3. Enhance authorization checks on all critical functions, especially those involving transaction processing or user role changes. 4. Monitor logs for unusual activities related to key manipulation or privilege escalation attempts. 5. Use multi-factor authentication to reduce the risk of compromised credentials being exploited. 6. Segment the e-commerce system to limit the impact of a potential breach. 7. Prepare for rapid deployment of patches once released by Farktor Software. 8. Conduct regular security audits and penetration testing focusing on authorization mechanisms. 9. Educate staff about the risks of phishing or social engineering that could lead to credential compromise. 10. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block suspicious manipulation attempts.
