TITLE

Webroot Software Desktop Firewall Firewall disable vulnerability

DESCRIPTION

Webroot Desktop Firewall before 1.3.0build52 allows local users to disable the firewall, even when password protection is enabled, via certain DeviceIoControl commands. The first issue is a buffer overflow vulnerability, due to a failure of the application to properly bounds check user-supplied data prior to copying it to an insufficiently sized memory buffer. Local attackers may exploit this first issue to execute arbitrary machine code with SYSTEM privileges. Attackers require the ability to modify the firewall's list of allowed applications. The second issue is an authentication bypass vulnerability. Local attackers may exploit the second issue to disable the firewall, aiding them in further attacks. These issues may only be exploited by local attackers with privileges allowing them to utilize 'DeviceIoControl()' to send commands to the firewall driver. These issues are reported to exist in version 1.3.0.43. Other versions may also be affected. 1) A boundary error in PWIWrapper.dll when deleting a program from the list of "allowed" programs can cause a stack-based buffer overflow in FirewallNTService.exe. Successful exploitation allows non-privileged users to execute arbitrary code with SYSTEM privileges, but requires the the ability to add and remove programs from the firewall's permitted application list. SOLUTION: Update to version 1.3.0 build 52. PROVIDED AND/OR DISCOVERED BY: Tan Chew Keong, Secunia Research.
