The VPN software within HP ThinPro does not safely handle user supplied input, which may be leveraged by an attacker to inject commands that will execute with root privileges.

HP ThinPro 4.4 through 6.1 mishandles the keyboard layout control panel and virtual keyboard application, which allows local users to bypass intended access restrictions and gain privileges via unspecified vectors.

A potential security vulnerability has been identified with the command line shell of the HP ThinPro operating system 6.1, 5.2.1, 5.2, 5.1, 5.0, and 4.4. The vulnerability could result in a local unauthorized elevation of privilege on an HP thin client device.

In HP ThinPro Linux 6.2, 6.2.1, 7.0 and 7.1, an attacker may be able to leverage the application filter bypass vulnerability to gain privileged access to create a file on the local file system whose presence puts the device in Administrative Mode, which will allow the attacker to executed commands with elevated privileges.

The Citrix Receiver wrapper function does not safely handle user supplied input, which may be leveraged by an attacker to inject commands that will execute with local user privileges.

A potential security vulnerability has been identified in HP ThinPro 7.2 Service Pack 8 (SP8). The security vulnerability in SP8 is not remedied after upgrading from SP8 to Service Pack 9 (SP9). HP has released Service Pack 10 (SP10) to remediate the potential vulnerability introduced in SP8.
