Netcool/NeuSecure Multiple Information Disclosure
------------------------------------------------------------------------


SUMMARY

" <http://www.micromuse.com/sols/dom_man/sec_man.html> Netcool/NeuSecure
is a security information management (SIM) platform designed to improve
the effectiveness, efficiency and visibility of security operations and
information risk management."

Improper permission handling and clear text storage allow attackers to
gain database and program passwords and remotely access Netcool/NeuSecure.

DETAILS

Vulnerable Systems:
* JReports-NeuSecure-3.0.236-1
* common-NeuSecure-3.0.236-1
* cms-NeuSecure-3.0.236-1

Default build of Netcool/NeuSecure has fixed directory permissions which
may lead to a regular user viewing configuration files containing
passwords.

-rw-r--r-- 1 ns ns 1228 Feb 3 10:25
/etc/neusecure.conf
drwxr-xr-x 15 ns ns 4096 Dec 1 12:43 /opt/NeuSecure
drwxr-xr-x 2 ns ns 4096 Jan 9 21:42
/opt/NeuSecure/etc/
-rw-r--r-- 1 ns ns 1334 Nov 16 18:44
/opt/NeuSecure/etc/cms-3.0.236.buildconf

Netcool/NeuSecure also store cleartext passwords in the configuration file
/etc/neusecure.conf:

/etc/neusecure.conf
ORACLE_HOME=
CMS_DBHOST=localhost
CMS_DBNAME=xxx
CMS_DBUSER=ns
CMS_DBPASS=nsl0ck
CMS_DBTYPE=mysql
CMSM_DBHOST=localhost
CMSM_DBNAME=xxxxx
CMSM_DBUSER=ns
CMSM_DBPASS=nsl0ck
FULL_REPORTS_STACKTRACE=true
JAVA_HEAP_SIZE=-Xmx256M
AAM=1
VULN_MEM=256
###########################
# JReports Config Variables #

RPT_DBHOST=reportserver
RPT_DBNAME=xxxx
RPT_DBUSER=ns
RPT_DBPASS=nsl0ck
RPT_DBTYPE=mysql
#RPT_DBHOST

Netcool/NeuSecure also store cleartext reporting of the <ns> user
password in the log viewable by an unprivileged user which leads to direct
mysql database connection and authentication with possibility to dump
users and passwords from the 'auth' table:

-rw-rw-r-- 1 ns ns 5102 Jan 9 12:17 /opt/NeuSecure/./bin/ns_archiver.log

Building NSSQLConnection "CMS Connection" type = mysql name = nsdbp
[1136830628.351]NSSQLConnection::NSSQLConnection => building mysql
connection to: hostString = "/tmp/mysql.sock@nsdbp" user = "ns" pass =
"nsl0ck"
[1136830628.356]connected successfully!
[1136830628.356]Connected using UNIX socket:/tmp/mysql.sock

Workaround:
* Change file read and write permission for only trusted users.
* Change database permission to allow only trusted users access.
