CyberRota Analysis
AI-GeneratedRuntipi versions 4.10.0 and earlier are vulnerable to a symbolic link attack during the backup restore process, allowing authenticated attackers to overwrite files outside the intended directory with arbitrary content. This could lead to unauthorized access or manipulation of sensitive application configurations. Users of Runtipi should prioritize upgrading to version 4.10.1 to mitigate this risk.

Original NVD Description
Runtipi is a personal homeserver orchestrator. In 4.10.0 and earlier, Runtipi accepts symbolic links from an attacker-controlled backup archive and copies them into live application paths during the backup restore flow. An authenticated attacker can plant user-config/app.env as a symlink to an arbitrary reachable path and then send PUT /api/user-config/demoapp3:_user with attacker-controlled appEnv content. FilesystemService.writeTextFile() follows the planted link, allowing content to be written outside the intended restore and user-config directory boundary with Runtipi process permissions. This issue is fixed in version 4.10.1.
