Security Bulletin: Rational Test Control Panel in Rational Test Workbench and Rational Test Virtualization Server affected by multiple Apache Tomcat vulnerabilities

Summary

Apache Tomcat is vulnerable to a number of security issues affecting the Rational Test Control Panel component in IBM Rational Test Workbench and Rational Test Virtualization Server.

Vulnerability Details

CVE-ID:CVE-2015-5345

**Description:**Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by an error when accessing a protected directory. By redirecting to the URL, an attacker could exploit this vulnerability to determine the presence of a directory.

CVSS Base Score: 5.300 CVSS Temporal Score:<https://exchange.xforce.ibmcloud.com/vulnerabilities/110857&gt; for more information *CVSS Environmental Score:**Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

---------------------------- **
CVE-ID: **CVE-2015-5346

Description: Apache Tomcat could allow a remote attacker to hijack a valid user’s session, caused by the failure to recycle the requestedSessionSSL field when recycling the Request object to use for a new request. By persuading a victim to visit a specially-crafted link and log into the application, a remote attacker could exploit this vulnerability to hijack another user’s account and possibly launch further attacks on the system.

CVSS Base Score: 4.300 CVSS Temporal Score:<https://exchange.xforce.ibmcloud.com/vulnerabilities/110854&gt; for more information *CVSS Environmental Score:**Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N)

----------------------------

CVE-ID: CVE-2015-5351

Description: Apache Tomcat is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input by the index page. By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to perform unauthorized actions. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.

CVSS Base Score: 8.800 CVSS Temporal Score:<https://exchange.xforce.ibmcloud.com/vulnerabilities/110859&gt; for more information *CVSS Environmental Score:**Undefined **CVSS Vector: **(CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

----------------------------

CVE-ID: CVE-2016-0706

Description: Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by the loading of the StatusManagerServlet during the configuration of a security manager. An attacker could exploit this vulnerability to obtain deployed applications and other sensitive information.

CVSS Base Score: 5.300 CVSS Temporal Score:<https://exchange.xforce.ibmcloud.com/vulnerabilities/110855&gt; for more information *CVSS Environmental Score:**Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

----------------------------

CVE-ID: CVE-2016-0714

Description: Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by an error in multiple session persistence mechanisms. By placing a malicious object into a session, an attacker could exploit this vulnerability to bypass a security manager and possibly execute arbitrary code on the system.

CVSS Base Score: 7.300 CVSS Temporal Score:<https://exchange.xforce.ibmcloud.com/vulnerabilities/110856&gt; for more information *CVSS Environmental Score:**Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

----------------------------

CVE-ID:CVE-2016-0763

**Description:**Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by an error in the ResourceLinkFactory.setGlobalContext() method. By injecting malicious content, an attacker could exploit this vulnerability to read and write arbitrary data.

CVSS Base Score: 6.500 CVSS Temporal Score:<https://exchange.xforce.ibmcloud.com/vulnerabilities/110858&gt; for more information *CVSS Environmental Score:**Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

----------------------------

CVE-ID: CVE-2015-5174

Description: Apache Tomcat could allow a remote attacker to traverse directories on the system. An attacker could send a specially-crafted URL request containing “dot dot” sequences (/…/) in the getResource(), getResourceAsStream() and getResourcePaths() ServletContext methods to obtain a directory listing for the directory.

**CVSS Base Score:**5.300
CVSS Temporal Score: <https://exchange.xforce.ibmcloud.com/vulnerabilities/110860&gt; for more information *CVSS Environmental Score:**Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

Affected Products and Versions

Rational Test Control Panel component in Rational Test Virtualization Server and Rational Test Workbench versions:

• All 8.0.x
• All 8.5.0.x

Versions 8.5.1 and later are unaffected as they do not use Apache Tomcat.

Remediation/Fixes

The fixes for the CVEs mentioned above have been incorporated into the 7.0.69 release of Apache Tomcat. You should upgrade your installation by following the instructions below.

1. Download the fix for your product from Fix Central:

• Rational Test Workbench - 7.0.69-Rational-RTW-Tomcat-zip

• Rational Test Virtualization Server - 7.0.69-Rational-RTVS-Tomcat-zip

• Unzip downloaded file to a directory.

• Stop the server.

• In the existing RTCP installation, save the files logging.properties and server.xml to a separate location.

The default installation locations for these files are:

• Windows: C:\Program Files\IBM\RationalTestControlPanel\conf\

• AIX, Linux, Solaris: /opt/IBM/RationalTestControlPanel/conf/

• Copy the contents of the unzipped Tomcat directory (except for the LICENSE file) into the RationalTestControlPanel directory, overwriting the existing files.

• Copy the two configuration files you saved earlier back into /conf.

• Start the server.

Notes:

• When updating an installation to a later version of Rational Test Control Panel, the security fix detailed above will have to be re-applied after the RTCP update
• When removing an installation that has had the security fix applied, not all the files will be removed by IBM Installation Manager, and some files will have to be removed manually.
