The Netscape Portable Runtime API running on Sun Solaris 10 operating system is prone to a local privilege-escalation vulnerability.
|
|
|
|
A successful exploit of this issue allows an attacker to gain superuser privileges, completely compromising the affected computer.
|
|
|
|
Version 4.6.1 running on Sun Solaris 10 is vulnerable to this issue.

# Local exploitation of a design error vulnerability in version 4.6.1 of
|
|
# NSPR, as included with Sun Microsystems Solaris 10, allows attackers to
|
|
# create or overwrite arbitrary files on the system. The problem exists
|
|
# because environment variables are used to create log files. Even when the
|
|
# program is setuid, users can specify a log file that will be created with
|
|
# elevated privileges (CVE-2006-4842).
|
|
#
|
|
# Usage:
|
|
# $ chmod +x raptor_libnspr
|
|
# $ ./raptor_libnspr
|
|
# [...]
|
|
# # id
|
|
# uid=0(root) gid=0(root)
|
|
# #
|
|
#
|
|
# Vulnerable platforms (SPARC):
|
|
# Solaris 10 without patch 119213-10 [tested]
|
|
#
|
|
# Vulnerable platforms (x86):
