TitanHQ SpamTitan 7.07

A sandbox escape issue was discovered in TitanHQ SpamTitan Gateway 7.07. It limits the admin user to a restricted shell, allowing execution of a small number of tools of the operating system. This restricted shell can be bypassed after changing the properties of the user admin in the operating system file /etc/passwd. This file cannot be accessed though the restricted shell, but it can be modified by abusing the Backup/Import Backup functionality of the web interface. An authenticated attacker would be able to obtain the file /var/tmp/admin.passwd after executing a Backup operation. This file can be manually modified to change the GUID of the user to 0 (root) and change the restricted shell to a normal shell /bin/sh. After the modification is done, the file can be recompressed to a .tar.bz file and imported again via the Import Backup functionality. The properties of the admin user will be overwritten and a root shell will be granted to the user upon the next successful login.

A sandbox escape issue was discovered in TitanHQ SpamTitan Gateway 7.07. It limits the admin user to a restricted shell, allowing execution of a small number of tools of the operating system. The restricted shell can be bypassed by presenting a fake vmware-tools ISO image to the guest virtual machine running SpamTitan Gateway. This ISO image should contain a valid Perl script at the vmware-freebsd-tools/vmware-tools-distrib/vmware-install.pl path. The fake ISO image will be mounted and the script wmware-install.pl will be executed with super-user privileges as soon as the hidden option to install VMware Tools is selected in the main menu of the restricted shell (option number 5). The contents of the script can be whatever the attacker wants, including a backdoor or similar.
