Multiple vulnerabilities in Apache Tomcat (Oracle November 2011)

Original Release Date: November 23, 2011
Last Revised: November 23, 2011
Number: ASA-2011-357
Risk Level: Low
Advisory Version: 1.0
Advisory Status: Final

1. Overview:

New Critical Patch Updates or Security Alerts have been issued by Oracle regarding vulnerabilities in Apache Tomcat.

Apache Tomcat 7.0.0 through 7.0.3, 6.0.x, and 5.5.x, when running within a SecurityManager, does not make the ServletContext attribute read-only, which allows local web applications to read or write files outside of the intended working directory, as demonstrated using a directory traversal attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3718 to this issue.

Multiple cross-site scripting (XSS) vulnerabilities in the Manager application in Apache Tomcat 6.0.12 through 6.0.29 and 7.0.0 through 7.0.4 allow remote attackers to inject arbitrary web script or HTML via the (1) orderBy or (2) sort parameter to sessionsList.jsp, or unspecified input to (3) sessionDetail.jsp or (4) java/org/apache/catalina/manager/JspHelper.java, related to use of untrusted web applications. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4172 to this issue.

The default configuration of Apache Tomcat 6.x does not include the HTTPOnly flag in a Set-Cookie header, which makes it easier for remote attackers to hijack a session via script access to a cookie. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4312 to this issue.

Multiple cross-site scripting (XSS) vulnerabilities in the HTML Manager Interface in Apache Tomcat 5.5 before 5.5.32, 6.0 before 6.0.30, and 7.0 before 7.0.6 allow remote attackers to inject arbitrary web script or HTML, as demonstrated via the display-name tag. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-0013 to this issue.

Apache Tomcat 7.0.0 through 7.0.6 and 6.0.0 through 6.0.30 does not enforce the maxHttpHeaderSize limit for requests involving the NIO HTTP connector, which allows remote attackers to cause a denial of service (OutOfMemoryError) via a crafted request. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-0534 to this issue.

2. Avaya System Products using a Solaris Operating System with affected packages installed:

Some Avaya system products are delivered with a Solaris Operating System. Actions to be taken on these products are described below.

Product: Affected Version(s): Risk Level: Actions:
Avaya IR 3.0, 4.0 Low This will not be addressed as no further updates are planned. Customers are advised to migrate to Voice Portal as described in the End of Sale Notice

Recommended Actions:
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 This is a low as Tomcat running on IR does not run within a security manager by default.
CVE-2010-4172 This is a low as the tomcat manager application is not used by default and its use is not supported. Such use would constitute non-standard user interaction.
CVE-2010-4312 This is a low as no critical applications or processes would be affected.
CVE-2011-0013 This is a low as the HTML manager interface is not used by default and its use is not supported. Such use would constitute non-standard user interaction.
CVE-2011-0534 This is a low as the NIO connector is not used by default
