CVE-2026-45053: CWE-434: Unrestricted Upload of File with Dangerous Type in cubecart v6
CubeCart is an ecommerce software solution. Prior to 6.7.0, an Authenticated Arbitrary File Upload vulnerability exists in the REST API File Manager endpoint (POST /api/v1/files) of CubeCart. The endpoint allows any holder of an API key with files:rw permission to upload PHP source files into the web-accessible images/source/ directory, where they are executed by the web server. Combined with a path-traversal flaw in the same endpoint's filepath parameter, a single API request writes a webshell anywhere the webserver process can write — including the document root — yielding full Remote Code Execution. This vulnerability is fixed in 6.7.0.
AI Analysis
Technical Summary
CubeCart ecommerce software versions before 6.7.0 have an authenticated arbitrary file upload vulnerability (CWE-434) in the REST API File Manager endpoint (POST /api/v1/files). Users with an API key possessing files:rw permission can upload PHP source files to the images/source/ directory, which are executed by the web server. Additionally, a path traversal flaw in the filepath parameter allows an attacker to write files anywhere writable by the web server, including the document root. This combination results in full remote code execution. The vulnerability is addressed in CubeCart version 6.7.0.
Potential Impact
Successful exploitation allows an authenticated attacker with files:rw API permissions to upload and execute arbitrary PHP code on the server, leading to full remote code execution. This compromises confidentiality, integrity, and availability of the affected system. The vulnerability is rated critical with a CVSS score of 9.1.
Mitigation Recommendations
This vulnerability is fixed in CubeCart version 6.7.0. Users should upgrade to version 6.7.0 or later to remediate this issue. No other official remediation or temporary fix information is provided. Patch status is not explicitly confirmed beyond the fix in 6.7.0; therefore, verify with the vendor advisory for the latest guidance.
