TITLE:
Apache Tomcat WAR Deployment Directory Traversal Weaknesses and
Security Issue

SECUNIA ADVISORY ID:
SA38316

VERIFY ADVISORY:
http://secunia.com/advisories/38316/

DESCRIPTION:
Some weaknesses and a security issue have been reported in Apache
Tomcat, which can be exploited by malicious users and malicious
people to manipulate certain data, and by malicious people to gain
access to potentially sensitive information.

1) In case of a failed undeploy, some autodeployed files may remain
with improper access restrictions, potentially leading to e.g. the
disclosure of sensitive information.

2) The application does not properly sanitise the file name of WAR
files, which can be exploited to e.g. delete files within the host's
work directory by deploying WAR files with directory traversal
sequences in the file name.

3) The application does not properly sanitise the file names of files
contained in a WAR file, which can be exploited to e.g. create
arbitrary files outside of the web root via a specially crafted WAR
file.
 
The weaknesses and the security issue are reported in version 6.0.0
to 6.0.20.

SOLUTION:
Update to version 6.0.24 or apply patch.
http://tomcat.apache.org/download-60.cgi

Patch:
http://svn.apache.org/viewvc?rev=892815&view=rev
