Seeyon Zhiyuan OA System Path Traversal File Upload

An arbitrary file upload vulnerability exists in the Zhiyuan OA platform via the wpsAssistServlet interface. The realFileType and fileId parameters are improperly validated during multipart file uploads, allowing unauthenticated attackers to upload crafted JSP files outside of intended directories using path traversal. Successful exploitation enables remote code execution as the uploaded file can be accessed and executed through the web server. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-01 UTC.

Qi'anxin TianQing Management Center rptsvr Arbitrary File Upload

QiAnXin TianQing Management Center versions up to and including 6.7.0.4130 contain a path traversal vulnerability in the rptsvr component that allows unauthenticated attackers to upload files to arbitrary locations on the server. The /rptsvr/upload endpoint fails to sanitize the filename parameter in multipart form-data requests, enabling path traversal. This allows attackers to place executable files in web-accessible directories, potentially leading to remote code execution. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-08-23 UTC.

Dahua Smart Park Integrated Management Platform Front-End Arbitrary File Upload

A path traversal vulnerability exists in the Dahua Smart Park Integrated Management Platform (also referred to as the Dahua Smart Campus Integrated Management Platform), affecting the SOAP-based GIS bitmap upload interface. The flaw allows unauthenticated remote attackers to upload arbitrary files to the server via crafted SOAP requests, including executable JSP payloads. Successful exploitation may lead to remote code execution (RCE) and full compromise of the affected system. The vulnerability is presumed to affect builds released prior to September 2023 and is said to be remediated in newer versions of the product, though the exact affected range remains undefined. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-02-15 UTC.
