Solaris AnswerBook2 Remote Command Execution Vulnerability

                                                source: http://www.securityfocus.com/bid/1556/info

A vulnerability exists in version 1.4.2 and prior of the AnswerBook2 server from Sun. It is possible for remote users who have administrative access to execute arbitrary commands on the machine running AnswerBook2. These commands will be executed with the privileges of user 'daemon'

One of the options you have while administering the AB2 is to rotate the
access and error logs. The server allows you to specify the target file 
where the logs will be rotated to. You can use ../../../../../this/file to
create and overwrite files outside the web server document root directory.
Further investigation showed that the server performs the following command
to rotate the server logs:

sh -c "cp /var/log/ab2/logs/original_log
/var/log/ab2/logs/USER_PROVIDED_TARGET" 

So an attacker could specify a destination log like "x ; uname -a" that will
translate to:

sh -c "cp /var/log/ab2/logs/original_log /var/log/abs/logs/x ; uname -a"
