Ubuntu 8.10 / 9.04 : tomcat6 vulnerabilities (USN-788-1)

medium Nessus Plugin ID 39419
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Ubuntu host is missing one or more security-related patches.


Iida Minehiko discovered that Tomcat did not properly normalise paths.
A remote attacker could send specially crafted requests to the server and bypass security restrictions, gaining access to sensitive content.

Yoshihito Fukuyama discovered that Tomcat did not properly handle errors when the Java AJP connector and mod_jk load balancing are used.
A remote attacker could send specially crafted requests containing invalid headers to the server and cause a temporary denial of service.

D. Matscheko and T. Hackner discovered that Tomcat did not properly handle malformed URL encoding of passwords when FORM authentication is used. A remote attacker could exploit this in order to enumerate valid usernames. (CVE-2009-0580)

Deniz Cevik discovered that Tomcat did not properly escape certain parameters in the example calendar application which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data (such as passwords), within the same domain. (CVE-2009-0781)

Philippe Prados discovered that Tomcat allowed web applications to replace the XML parser used by other web applications. Local users could exploit this to bypass security restrictions and gain access to certain sensitive files. (CVE-2009-0783).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
