A local privilege escalation vulnerability exists in the Infotecs products (ViPNet Client, SafeDisk, Personal Firewall and possibly other products), which could be exploited by an attacker to execute commands on the affected machine under the context of the SYSTEM user or user with local administrative privileges.
The vulnerability exists because Infotecs products installs to folder with insecure permissions. "Everyone" group has "Full Control" rights to the files/folders in the following path: "%Program Files%\Infotecs\[product_name]". It means that any unprivileged user can modify, delete or change permissions of any file in data the folder consists of data, executable and configuration files.
