CVE-2017-7281
HighSummary
An issue was discovered in Unitrends Enterprise Backup before version 9.1.2 related to a lack of input sanitization in the createReportName and saveReport functions. This allows an authenticated user to create a randomly named file on disk with a user-controlled extension, contents, and path, leading to remote code execution.
Risk Assessment
The lack of proper input sanitization poses a risk of remote code execution, which can lead to serious security breaches within the organization.
Recommendation
It is recommended to update Unitrends Enterprise Backup to version 9.1.2 or later and to implement additional security measures to restrict the ability of users to input unsafe data.
