.NET deserialization vulnerability in the Microsoft Exchange Control Panel web page allows authenticated attackers to execute OS commands with SYSTEM privileges.

The lack of randomization in the validationKey and decryptionKey values at installation allows an attacker to create a crafted viewstate to execute OS commands via .NET deserialization.
An unauthenticated OS command injection vulnerability in rConfig using the rootUname parameter present in ajaxServerSettingsChk.php allows an attacker to send a request that will attempt to execute OS commands with permissions of the rConfig process on the host system.

Also, an authenticated OS command injection vulnerability using the catCommand parameter present in search.crud.php allows an attackers to do the same as previous, but credentials are required.

Server-side template injection vulnerability in Jira Server and Data Center, in the ContactAdministrators and the SendBulkMail actions.



If an SMTP server has been configured, then an unauthenticated user can execute code on vulnerable systems using the ContactAdministrators action if the "Contact Administrators Form" is enabled; or an authenticated user can execute code on vulnerable systems using the SendBulkMail action if the user has "JIRA Administrators" access.
