tomcat5 security update (RHSA-2011-1845)

Original Release Date: December 23, 2011
Last Revised: August 29, 2012
Number: ASA-2011-424
Risk Level: Low
Advisory Version: 2.0
Advisory Status: Final

1. Overview:

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

It was found that web applications could modify the location of the Tomcat host's work directory. As web applications deployed on Tomcat have read and write access to this directory, a malicious web application could use this flaw to trick Tomcat into giving it read and write access to an arbitrary directory on the file system. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3718 to this issue.

A cross-site scripting (XSS) flaw was found in the Manager application, used for managing web applications on Apache Tomcat. A malicious web application could use this flaw to conduct an XSS attack, leading to arbitrary web script execution with the privileges of victims who are logged into and viewing Manager application web pages. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-0013 to this issue.

Multiple flaws were found in the way Tomcat handled HTTP DIGEST authentication. These flaws weakened the Tomcat HTTP DIGEST authentication implementation, subjecting it to some of the weaknesses of HTTP BASIC authentication, for example, allowing remote attackers to perform session replay attacks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-1184 to this issue.

A flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception occurred when creating a new user with a JMX client, that user's password was logged to Tomcat log files. Note: By default, only administrators have access to such log files. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-2204 to this issue.

2. Avaya System Products using a modified version of RHEL5 with affected components/packages installed:
Product: Affected Version(s): Risk Level: Actions:
Avaya Aura® System Manager 6.1.x, 6.2, 6.2.1 Low Upgrade to SMGR 6.2.2 or later.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place, risk to Avaya products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but customers should not modify the System Product operating system or application unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:

Vulnerability Mitigating Factors
CVE-2010-3718
Rated a Low since only authenticated users could deploy Web apps on the Tomcat host.
CVE-2011-1184
Rated a Low since all products use secure (HTTPS) Web pages for authentication purposes.
CVE-2011-0013
Rated a Low since non-standard user interaction is required to exploit this vulnerability.
CVE-2011-2204
Rated a Low since only administrators have access to Tomcat log files.

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.

Product: Actions:
Avaya Aura® Application Enablement Services 4.x/5.x Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the AES application.
CVLAN Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the CVLAN application.
Avaya Aura® Experience Portal Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the EP application.
