DESCRIPTION:
Buguroo Offensive Security has discovered a vulnerability in Trend
Micro InterScan Web Security Suite for Linux, which can be exploited
by malicious, local users to gain escalated privileges.

The vulnerability is caused due to an error in the setuid/setgid root
/opt/trend/iwss/data/patch/bin/patchCmd binary when performing certain
actions. This can be exploited to gain root privileges by creating a
PatchExe.sh or RollbackExe.sh script in the CWD and executing the
binary.

The vulnerability is confirmed in version 3.1 Build 1027 for Linux.
Other versions may also be affected.

SOLUTION:
Restrict access to trusted users only.
