TITLE:
Symantec pcAnywhere CIF Files Privilege Escalation

SECUNIA ADVISORY ID:
SA21113

VERIFY ADVISORY:
http://secunia.com/advisories/21113/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Symantec pcAnywhere 12.x
http://secunia.com/product/11089/

DESCRIPTION:
Zee has reported a security issue in Symantec pcAnywhere, which can
be exploited by malicious, local users to gain escalated privileges.

The problem is caused due to CIF files containing a superuser flag
and being stored insecurely by default in "Documents and Settings\All
Users\Application Data\Symantec\pcAnywhere\Hosts\" where any user can
read the contents of files and create new files. This can be
exploited to gain administrative user privileges via pcAnywhere by
crafting a new CIF file, setting the superuser flag, and placing the
file in the "Hosts" directory.

The security issue has been reported in version 12.5. Other versions
may also be affected.

SOLUTION:
Grant only trusted users access to affected systems.

PROVIDED AND/OR DISCOVERED BY:
Zee
