Security Bulletin: TADDM uses weak SSL certificates (CVE-2012-5770)
Document information
Tivoli Application Dependency Discovery Manager
Software version:
7.2, 7.2.1
Operating system(s):
AIX, Linux, Solaris, Windows
Reference #:
1626029
Modified date:
2013-03-05
Abstract
IBM Tivoli Application Dependency Discovery Manager SSL certificate uses weak
MD5 hash algorithm
Content
VULNERABILITY DETAILS:
DESCRIPTION:
TADDM uses weak certificates for SSL communication what can lead to man in the
middle attack. The attacker must have access to traffic between TADDM server
and its client (GUI or API) to be able to hijack and break the certificate.
If more powerful hash algorithm is used the certificate is much more difficult
to break.
CVEID: CVE-2012-5770

Each customer should generate their own security certificates that would
uniquely identify the customer. The steps to do that are listed in following
section.
Workaround(s):
The certificates can be generated manually issuing following commands:
<taddm_dist_dir>/external/<jdk-for-platform>/bin/keytool -delete -alias
collation -keystore <taddm_dist_dir>/etc/serverkeys -storepass <ssl-password>
<taddm_dist_dir>external/<jdk-for-platform>/bin/keytool -genkey -alias
collation -keystore <taddm_dist_dir>/etc/serverkeys -validity 3650 -keyAlg
RSA -sigalg SHA256WithRSA -keypass <ssl-password> -storepass <ssl-password>
- -dname "CN=<TADDM_SERVER_FQDN>, OU=Engineering, O=IBM, L=Palo Alto,
S=California, C=US"
<taddm_dist_dir>external/<jdk-for-platform>/bin/keytool -export -alias
collation -noprompt -keystore <taddm_dist_dir>/etc/serverkeys -keypass
<ssl-password> -storepass <ssl-password> -file <taddm_dist_dir>/cert.tmp
<taddm_dist_dir>external/<jdk-for-platform>/bin/keytool -delete -alias
collation -noprompt -keystore <taddm_dist_dir>/etc/jssecacerts.cert
- -storepass <ssl-password>
<taddm_dist_dir>external/<jdk-for-platform>/bin/keytool -import -alias
collation -noprompt -keystore <taddm_dist_dir>/etc/jssecacerts.cert -keypass
<ssl-password> -storepass <ssl-password> -file <taddm_dist_dir>/cert.tmp
where:
<taddm_dist_dir> - the "dist" dir where taddm is installed
<jdk-for-platform> - jdk dir dedicated for Customer's platform
<ssl-password> - value of com.collation.sslpassphrase
<TADDM_SERVER_FQDN> - taddm server fqdn
NOTE: please backup the existing files before:
<taddm_dist_dir>/etc/serverkeys
<taddm_dist_dir>/etc/jssecacerts.cert
Mitigation(s):
If possible access to TADDM server should be restricted to certain selected
machines by using e.g. by using iptables. This way the potential attacker must
hijack machine allowed to access to conduct MiM attack.

Security Bulletin: TADDM Web UI security vulnerabilities (CVE-2012-5939,
CVE-2012-5942)
Document information
Tivoli Application Dependency Discovery Manager
Software version:
7.2, 7.2.1
Operating system(s):
AIX, Linux, Solaris, Windows
Reference #:
1625935
Modified date:
2013-03-01
Abstract
IBM Tivoli Application Dependency Discovery Manager has security
vulnerabilities in Web User Interface (Data Management Portal)
Content
VULNERABILITY DETAILS:
CVEID: CVE-2012-5939
DESCRIPTION:
IBM Tivoli Application Dependency Discovery Manager is vulnerable to cross-site
scripting, caused by improper validation of user supplied input by the
Welcome.do script. A remote authenticated attacker could exploit this
vulnerability using a specially crafted URL to execute script in a victim's
Web browser within the security context of the hosting Web site, once the URL
is clicked. An attacker could use this vulnerability to steal the victim's
cookie based authentication credentials.
CVSS Base Score: 3.5

CVEID: CVE-2012-5942
DESCRIPTION:
IBM Tivoli Application Dependency Discovery Manager is vulnerable to content
spoofing, caused by improper validation of user supplied input. A remote attacker
could exploit this vulnerability to inject malicious content into a Web application
page, which would appear to be legitimate and could be used to launch various
attacks against users of the targeted Web application, including phishing, URL
redirection, and cross-site request forgery.
