Subject: [SECURITY] CVE-2009-2902 Apache Tomcat unexpected file deletion in
 work directory

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

CVE-2009-2902: Apache Tomcat unexpected file deletion in work directory

Severity: Low

Vendor:
The Apache Software Foundation

Versions Affected:
Tomcat 5.5.0 to 5.5.28
Tomcat 6.0.0 to 6.0.20
The unsupported Tomcat 3.x, 4.x and 5.0.x versions may be also
affected.

Description:
When deploying WAR files, the WAR file names were not checked for
directory traversal attempts. This allows an attacker to cause the
deletion of the current contents of the host's work directory which may
cause problems for currently running applications.

Mitigation:
6.0.x users should upgrade to 6.0.24 or apply this patch:
http://svn.apache.org/viewvc?rev=892815&view=rev
5.5.x users should upgrade to 5.5.29 when released or apply this patch:
http://svn.apache.org/viewvc?rev=902650&view=rev
Note: the patches also address CVE-2009-2693 and CVE-2009-2901.
Alternatively, users of all Tomcat versions may mitigate this issue by
manually validating the contents of untrusted WAR files before deployment.

Example:
Deploying and undeploying a WAR named "...war" causes the all files and
subdirectories in "work/<engine name>/<host name>" to be removed.

Credit:
This issue was discovered by the Apache Tomcat security team
