Eclipse BaSyx Java Server SDK是美国Eclipse基金会的一款基于Java的服务器软件开发工具包。 Eclipse BaSyx Java Server SDK存在安全漏洞，该漏洞源于AAS thumbnail API接受了客户端控制的fileName请求参数，并经过存储库文件处理未对路径进行规范化或限制，可能导致远程攻击者通过MongoDB后端上传缩略图内容，触发缩略图检索时写入任意文件路径，进而可能导致远程代码执行。以下版本受到影响：2.0.0-milestone-05版本至

Vulnerability Description
In Eclipse BaSyx Java Server SDK versions 2.0.0-milestone-05 to 2.0.0-milestone-12, deployments using the MongoDB backend are vulnerable to an unauthenticated arbitrary file write through the AAS thumbnail API. The AAS thumbnail upload path accepted a client-controlled fileName request parameter and passed it through repository file handling as both a repository key and, during thumbnail retrieval, a local filesystem path. With the MongoDB file repository, the supplied filename was treated as an opaque GridFS key and was not normalized or restricted as a filesystem path. A remote attacker could upload thumbnail content using an absolute or traversal-style filename, then trigger thumbnail retrieval so that the uploaded bytes were written to the attacker-chosen path on the server filesystem. This could allow writing files anywhere the Java process has permission to write and may lead to remote code execution. The default InMemory backend is not affected by this specific path because it normalizes and restricts file paths to its temporary directory. The issue is fixed in Eclipse BaSyx Java Server SDK 2.0.0-milestone-13.
