AI Powered Q&A
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows remote authenticated users with administrator privileges to write specific files containing non-sensitive information via a path traversal flaw. Since the information involved is non-sensitive and the attack requires administrator privileges, the direct impact on compliance with standards like GDPR or HIPAA is limited.
However, improper file write capabilities could potentially lead to integrity issues or unauthorized modifications, which might indirectly affect compliance if exploited in a broader attack scenario.
Can you explain this vulnerability to me?
This vulnerability is a 'Path Traversal' issue in the Backup.Repository webapi component of Synology Hyper Backup versions before 4.1.2-4036.
It allows remote authenticated users who have administrator privileges to write specific files containing non-sensitive information by exploiting improper limitation of a pathname to a restricted directory.
How can this vulnerability impact me? :
The vulnerability can allow an attacker with administrator access to write files in restricted directories, potentially leading to integrity issues.
According to the CVSS score of 4.1, the impact is limited to integrity (I:L) with no impact on confidentiality or availability.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should update Synology Hyper Backup to version 4.1.2-4036 or later, as the issue is fixed in this release.
Ensure that only trusted administrators have access to the Backup.Repository webapi component, since the vulnerability requires administrator privileges.
