CVE-2026-2165 is a vulnerability identified in detronetdip E-commerce version 1.0.0, specifically within the Account Creation Endpoint located at /Admin/assets/backend/seller/add_seller.php. The flaw arises from a missing authentication mechanism when processing the 'email' argument, allowing an attacker to remotely manipulate this parameter to bypass authentication controls. This enables unauthorized creation of seller accounts without any prior authentication, privilege, or user interaction. The vulnerability is remotely exploitable over the network with low attack complexity and no required privileges, making it accessible to a wide range of attackers. The CVSS 4.0 vector indicates no confidentiality, integrity, or availability impact is critical but low to limited impact on these aspects, resulting in a medium severity rating with a score of 6.9. The vendor was informed early but has not yet responded or released a patch. The availability of a public exploit increases the risk of active exploitation. This vulnerability could be leveraged to inject malicious sellers into the platform, potentially facilitating fraud, unauthorized transactions, or further lateral movement within the e-commerce system. Given the lack of authentication, attackers might also enumerate or manipulate seller data, undermining system integrity and trustworthiness.

For European organizations using detronetdip E-commerce 1.0.0, this vulnerability poses a significant risk to the integrity and trustworthiness of their e-commerce operations. Unauthorized creation of seller accounts can lead to fraudulent listings, financial losses, reputational damage, and potential regulatory non-compliance, especially under GDPR if personal data is mishandled. Attackers could use fake seller accounts to conduct scams, distribute counterfeit goods, or launch further attacks such as phishing or malware distribution. The lack of authentication increases the attack surface and ease of exploitation, potentially affecting availability if attackers flood the system with bogus accounts. This could disrupt legitimate seller operations and customer experience. The public availability of an exploit heightens the urgency for mitigation. European e-commerce businesses relying on this platform may face operational disruptions and legal liabilities if exploited. Additionally, the vulnerability could be leveraged as an entry point for broader supply chain attacks or to compromise payment processing workflows.

Immediate mitigation steps include implementing strict access controls and authentication checks on the /Admin/assets/backend/seller/add_seller.php endpoint to ensure only authorized users can create seller accounts. Organizations should audit their current installations of detronetdip E-commerce 1.0.0 to identify exposure. Network-level protections such as web application firewalls (WAFs) can be configured to detect and block suspicious requests targeting the vulnerable endpoint, especially those manipulating the 'email' parameter. Monitoring and alerting on unusual seller account creation activity should be established to detect exploitation attempts. If possible, disable or restrict the seller account creation feature until a vendor patch is available. Organizations should also review logs for signs of exploitation and conduct a thorough security assessment of their e-commerce environment. Engaging with the vendor or community to obtain updates or patches is critical. As a longer-term measure, consider upgrading to a newer, patched version or migrating to a more secure e-commerce platform. Employee training on recognizing fraudulent seller activity and incident response planning specific to e-commerce threats will enhance resilience.
