OpenProject BIM BCF XML Import: <Snapshot> Path Traversal Leads to Arbitrary Local File Read (AFR)

OpenProject is an open-source, web-based project management software. Prior to 17.2.0, an authenticated project member with BCF import permissions can upload a crafted .bcf archive where the <Snapshot> value in markup.bcf is manipulated to contain an absolute or traversal local path (for example: /etc/passwd or ../../../../etc/passwd). During import, this untrusted <Snapshot> value is used as file.path during attachment processing. As a result, local filesystem content can be read outside the intended ZIP scope. This results in an Arbitrary File Read (AFR) within the read permissions of the OpenProject application user. This vulnerability is fixed in 17.2.0.

对路径名的限制不恰当(路径遍历)

OpenProject 路径遍历漏洞

OpenProject是OpenProject开源的一个基于Web的项目管理软件。 OpenProject 17.2.0之前版本存在路径遍历漏洞，该漏洞源于具有BCF导入权限的经过身份验证的项目成员可上传特制的.bcf存档，其中markup.bcf中的Snapshot值被操纵以包含绝对或遍历本地路径，可能导致在OpenProject应用程序用户读取权限内进行任意文件读取。
