CVE-2026-2164 is a vulnerability identified in detronetdip E-commerce version 1.0.0, specifically in the file /seller/assets/backend/profile/addadhar.php. The vulnerability arises from improper handling of the File argument, which allows an attacker to perform unrestricted file uploads. This means that an attacker can remotely upload arbitrary files, including potentially malicious scripts or executables, without any authentication or user interaction required. The vulnerability has a CVSS 4.0 base score of 6.9 (medium severity), with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability. The exploit code has been publicly released, increasing the likelihood of exploitation, although no confirmed attacks in the wild have been reported yet. The vendor was notified early but has not responded or provided a patch, leaving systems exposed. The unrestricted upload can lead to remote code execution, data theft, defacement, or further compromise of the underlying server and network. This vulnerability is critical for e-commerce platforms as it can undermine customer trust and lead to financial losses.

For European organizations using detronetdip E-commerce 1.0.0, this vulnerability poses significant risks including unauthorized access to internal systems, data breaches involving sensitive customer and payment information, and potential service disruptions due to malicious file uploads. Attackers could deploy web shells or malware, enabling persistent access and lateral movement within the network. This could lead to reputational damage, regulatory penalties under GDPR for data protection failures, and financial losses. Given the public availability of exploit code, the threat landscape is heightened, especially for organizations that have not applied mitigations or do not have compensating controls. The impact is more severe for organizations with high transaction volumes or those handling sensitive personal data. Additionally, the lack of vendor response delays remediation, increasing exposure time.

1. Immediately implement strict server-side validation of uploaded files, including checking file types, extensions, and content signatures to prevent malicious files. 2. Restrict upload directories with minimal permissions, ensuring uploaded files cannot be executed as code. 3. Employ web application firewalls (WAF) with rules to detect and block suspicious upload attempts targeting the vulnerable endpoint. 4. Monitor logs for unusual file upload activity or access patterns to detect exploitation attempts early. 5. Isolate the upload functionality in a sandboxed environment to limit potential damage. 6. If possible, disable or restrict the vulnerable upload feature until a vendor patch is available. 7. Conduct regular security assessments and penetration testing focused on file upload mechanisms. 8. Educate development teams on secure coding practices related to file handling to prevent similar issues in future versions.
