Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

MISP 存在一个文件处理漏洞，可能允许特定的已认证用户让服务器读取文件或访问内部网络服务。 在导入 XML 文件时，MISP 未正确验证上传的内容是否确实是 XML 格式。因此，拥有数据修改权限的用户可以上传一个包含本地文件路径或 Web 地址的文件。 如果提供的是本地文件路径，MISP 将从服务器上读取该文件；如果提供的是 URL，MISP 会向该地址发起请求，包括那些可能仅可从组织内部网络访问的系统。 因此，该漏洞可能导致敏感本地文件泄露，并允许对内部服务发起未授权的请求。 利用该漏洞需要具有修改权限的有效

Vulnerability Title
MISP Arbitrary Local File Read and SSRF via MISP Export Upload
Source: CVE Program / CVE List V5
Vulnerability Description
MISP has a file-handling vulnerability that could let certain authenticated users make the server read files or access internal network services. When importing an XML file, MISP did not properly verify that the uploaded content was actually XML. Because of this, a user with permission to modify data could upload a file containing a local file path or a web address instead. If a local file path was supplied, MISP could read that file from the server. If a URL was supplied, MISP could make a request to that address, including systems that may only be reachable from inside the organization’s network. The vulnerability could therefore expose sensitive local files and allow unauthorized requests to internal services. Exploitation required a valid MISP account with modify permissions, but no additional user interaction was needed. Version affected: <2.5.47
