Quick assessment

Affected
Apache Software Foundation Apache MINA SSHD
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache MINA SSHD是美国阿帕奇（Apache）基金会的一个纯 Java 库，支持客户端和服务器端的 SSH 协议。 Apache MINA SSHD存在安全漏洞，该漏洞源于路径遍历，可能导致已认证用户通过SSH访问配置的git服务器根目录之外的git仓库。

Vulnerability Title
Apache MINA SSHD: Path traversal in org.apache.sshd:sshd-git
Source: CVE Program / CVE List V5
Vulnerability Description
Path traversal vulnerability in Apache MINA SSHD bundle sshd-git. Lack of path validation in git-upload-pack, git-receive-pack, and other git operations allows users authenticated over SSH access to git repositories outside the configured git server root directory. Applications are affected if they use org.apache.sshd:sshd-git. Applications not using sshd-git are not affected. Users are advised to upgrade affected applications to Apche MINA SSHD 2.18.0, which fixes the issue. The issue also is present in the pre-release milestones 3.0.0-M1 to 3.0.0-M3 for a new upcoming new major version 3.0.0. Again, applications are affected only if they use sshd-git. Upgrade affected applications to 3.0.0-M4. We would like to point out that a professional git server should not rely solely on file system layout and permissions, but should implement additional security controls to govern access to git repositories and operations allowed on particular git repositories.
