Executive Summary

This vulnerability is a Path Traversal issue in the Backup Task functionality of Synology Hyper Backup versions before 4.1.2-4036. It allows remote authenticated users to write specific files outside the intended restricted directory by exploiting improper limitation of the pathname.

Impact Analysis

An attacker who is remotely authenticated can write files to locations they should not have access to. This could lead to unauthorized modification of files, potentially compromising the integrity of the backup system or other parts of the affected system.

Compliance Impact

The vulnerability in Synology Hyper Backup allows remote authenticated users to write specific files via path traversal, which could potentially lead to unauthorized modification of backup data.

Such unauthorized file modifications may impact the integrity and security of backup data, which are critical aspects of compliance with standards like GDPR and HIPAA that require protection of sensitive data and ensuring data integrity.

However, the provided information does not explicitly describe the direct impact of this vulnerability on compliance with these regulations.

Mitigation Strategies
