TITLE

Vulnerability in Epson printer driver installer where access permissions are changed

DESCRIPTION

The Seiko Epson printer driver installers for LP-S9000 before 4.1.11 and LP-S7100 before 4.1.7, or as downloaded from the vendor between May 2010 and 20101125, set weak permissions for the "C:\Program Files" folder, which might allow local users to bypass intended access restrictions and create or modify arbitrary files and directories. As a result, users that do not have permission to access that folder can gain access to that folder. According to the developer, printer drivers that were included with the product or downloaded from the developer website from the initial release of May 2010 through November 25, 2010 are affected by this vulnerability. Also, users of Windows Vista and later operating systems are not affected. The Epson LP-S7100 / LP-S9000 is a family of high performance printers. There is a problem with the Epson LP-S7100 / LP-S9000 driver installation, allowing local users to increase privileges. Because the default permissions for \"C:\\Program Files\" and its subdirectories are not set correctly (\"Everyone\" group is fully controlled), local users can exploit the vulnerability to overwrite any file in these folders, resulting in elevation of privilege. Local attackers can exploit this issue to gain elevated privileges on affected devices. The following driver versions are vulnerable: LP-S7100 4.1.0fi through 4.1.7fi and 4.1.0hi through 4.1.7hi LP-S9000 4.1.0fc through 4.1.11fc and 4.1.0hc through 4.1.11hc. ---------------------------------------------------------------------- Secure your corporate defenses and reduce complexity in handling vulnerability threats with the new Secunia Vulnerability Intelligence Manager (VIM).
