SiYuan has Arbitrary File Write via /api/file/copyFile leading to RCE

概要

SiYuan has Arbitrary File Write via /api/file/copyFile leading to RCE

原文の説明

取得元が公開している説明をそのまま載せています (多くは英語)。

SiYuan is a personal knowledge management system. Prior to version 3.5.5, the /api/file/copyFile endpoint does not validate the dest parameter, allowing authenticated users to write files to arbitrary locations on the filesystem. This can lead to Remote Code Execution (RCE) by writing to sensitive locations such as cron jobs, SSH authorized_keys, or shell configuration files. This issue has been patched in version 3.5.5.
