Unitrends Enterprise Backup vulnerabilities

An authenticated user of Unitrends Enterprise Backup before version 9.1.2 can execute arbitrary OS commands by sending a specially crafted filename to the /api/restore/download-files endpoint, related to the downloadFiles function in api/includes/restore.php.

An attacker that has hijacked a Unitrends Enterprise Backup (before 9.1.2) web server session can leverage api/includes/users.php to change the password of the logged in account without knowing the current password. This allows for an account takeover.

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.

In Unitrends Enterprise Backup 7.3.0, a vulnerability allows remote attackers to bypass authentication by setting the auth parameter to a certain string.

Unitrends Enterprise Backup version 7.3.0 allows remote authenticated users to execute arbitrary commands via shell metacharacters in the comm parameter to recoveryconsole/bpl/snmpd.php.

An issue was discovered in api/includes/systems.php in Unitrends Enterprise Backup before version 9.0.0. User input is not properly filtered before being sent to a popen function, allowing for remote code execution.

An unprivileged user of the Unitrends Enterprise Backup before version 9.0.0 can escalate to root privileges by modifying the 'token' cookie issued at login.
