TITLE:
NOD32 Privilege Escalation Vulnerabilities

SECUNIA ADVISORY ID:
SA19054

VERIFY ADVISORY:
http://secunia.com/advisories/19054/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
NOD32 for Windows NT/2000/XP/2003 2.x
http://secunia.com/product/1066/

DESCRIPTION:
Two vulnerabilities have been reported in NOD32, which can be
exploited by malicious, local users to gain escalated privileges.

1) The NOD32 GUI (nod32.exe) runs with SYSTEM privileges when a
scheduled on-demand scan is being run by the scheduler. This can be
exploited to invoke cmd.exe with SYSTEM privileges when a scheduled
scan is running.

The vulnerability has been confirmed in version 2.5 for
WinNT/2k/XP/2003 (nod32krn.exe/nod32.exe 2.51.20.0). Other versions
may also be affected.

2) The program doesn't drop its SYSTEM privileges before allowing a
user to use the "Restore to..." feature to restore a quarantined
file. This can be exploited to write a file to an arbitrary directory
with SYSTEM privileges if a file with the given filename doesn't
already exist.

SOLUTION:
Update to version 2.51.26 or later.
