PC-cillin Internet Security Insecure Default Directory Permissions

SECUNIA ADVISORY ID:
SA19282

VERIFY ADVISORY:
http://secunia.com/advisories/19282/

CRITICAL:
Less critical

IMPACT:
Manipulation of data, Privilege escalation

WHERE:
Local system

SOFTWARE:
Trend Micro PC-cillin Internet Security 2006 / 14.x
http://secunia.com/product/8828/

DESCRIPTION:
Dominique GREGOIRE has discovered a security issue in PC-cillin
Internet Security, which can be exploited by malicious, local users
to gain escalated privileges.

The problem is that insecure default permissions are set on the
application directory (grants "Everyone" group "Full Control" on the
"Internet Security 14" directory or grants "Users" group "Full
Control" on the "Internet Security 2006" directory depending on the
installed version). This can be exploited to remove, manipulate, and
replace any of the application's files.

The security issue has been confirmed in versions 14.00.1485 and 2006
(14.10.0.1023). Other versions may also be affected.

SOLUTION:
Grant only trusted users access to affected systems.

Set proper permissions on the "Internet Security 14" / "Internet
Security 2006" directory and all child objects. This may affect the
functionality.
