Sun Solaris printd arbitrary file deletion
ISS X-Force is tracking a vulnerability within the Sun Solaris printd daemon
and a corresponding exploit that is now publicly available. Sun Solaris
versions 7, 8, 9, and 10 could allow a local or remote attacker to delete
arbitrary files on a system caused by a vulnerability in the printd daemon. The
print daemon is installed by default and usually with root privileges. A remote
or local attacker could exploit this vulnerability and delete arbitrary files,
including system files.
The Sun Solaris printd daemon is the default printing service for the Solaris
operating system and can typically be found on all systems following a standard
installation. By successfully exploiting this vulnerability an attacker
is able to delete arbitrary files on a vulnerable system. In doing so, an
attacker may cause the system to fail dramatically and lead to a loss of service.
With selective deletion of files, it may be possible for an attacker to leverage
the missing files to exploit other, older vulnerabilities, which would
provide interactive access to the vulnerable system. The vulnerable printd service
is typically installed with root permissions; thereby allowing the attacker to
delete any system file accessible to that account.
