Number: ASA-2007-206

Advisory Version: 2.0
Advisory Status: Final

1. Overview:

Apache Tomcat is a servlet container which powers various Java-based web tools.

A number of vulnerabilities have been reported in tomcat.

A vulnerability in the way tomcat accepts content-length headers could allow an attacker to poison a web-cache, bypass a web firewall, or conduct cross-site scripting (XSS) attacks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2090 to this issue.

In some proxy configurations, a crafted HTTP request could be sent to view non-proxied content. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-0450 to this issue.

Several JSP examples display unfiltered values, which could allow a remote hacker to perform XSS attacks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2006-7195 and CVE-2006-7196 to these issues.

The default Tomcat configuration permits using insecure SSL cipher suites, including the anonymous cipher suite. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-1858 to this issue.

Directory listings are enabled by default in Tomcat. In instances where the web server administrator has not disabled directory listings, all unprotected information in the document root is viewable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-3835 to this issue.

More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:

2. Avaya System Products with tomcat installed:

Product: Affected Version(s): Risk Level: Actions:
Avaya AES All Low Upgrade to AES 4.2.2.

Recommended Actions:
For all system products which use vulnerable versions of tomcat, Avaya recommends that customers restrict local and network access to the server. This restriction should be enforced through the use of physical security, firewalls, ACLs, VPNs, and other generally-accepted networking practices until such time as an update becomes available and can be installed.

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.
