CVE-2023-6120Network attack vector

Administrator arbitrary certificate upload via path traversal

Published Dec 9, 2023 · Updated Apr 8, 2026

Directory traversal in Welcart e-Commerce 2.9.6 and earlier allows remote authenticated users to upload certificate files anywhere on the server. The upload_certificate_file function accepts attacker-controlled path components without constraining the destination to its intended directory. Administrator access is required, and the operation is limited to .pem or .crt files but can place or overwrite certificate material in arbitrary server paths.
