An OS command injection vulnerability in the openmediavault-md plugin of OpenMediaVault v8.0.4-1 allows attackers to execute arbitrary commands as root via injecting shell metacharacters.

An issue was discovered in the changePassword method in file /usr/share/php/openmediavault/system/user.inc in OpenMediaVault 7.4.17 allowing local authenticated attackers to escalate privileges to root.

Multiple Cross-site scripting (XSS) vulnerabilities in rpc.php in OpenMediaVault release 2.1 in Access Rights Management(Users) functionality allows attackers to inject arbitrary web scripts and execute malicious scripts within an authenticated client's browser.

The Cron service in rpc.php in OpenMediaVault allows remote authenticated users to execute cron jobs as arbitrary users and execute arbitrary commands via the username parameter.

openmediavault before 4.1.36 and 5.x before 5.5.12 allows authenticated PHP code injection attacks, via the sortfield POST parameter of rpc.php, because json_encode_safe is not used in config/databasebackend.inc. Successful exploitation allows arbitrary command execution on the underlying operating system as root.
