Arrow  Advisory Content :  

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

CVE-2008-2370: Apache Tomcat information disclosure vulnerability

Severity: Important

Vendor:
The Apache Software Foundation

Versions Affected:
Tomcat 4.1.0 to 4.1.37
Tomcat 5.5.0 to 5.5.26
Tomcat 6.0.0 to 6.0.16
The unsupported Tomcat 3.x, 4.0.x and 5.0.x versions may be also affected

Description:
When using a RequestDispatcher the target path was normalised before the
query string was removed. A request that included a specially crafted
request parameter could be used to access content that would otherwise be
protected by a security constraint or by locating it in under the WEB-INF
directory.

Mitigation:
6.0.x users should upgrade to 6.0.18
5.5.x users should obtain the latest source from svn or apply this patch
which will be included from 5.5.27
http://svn.apache.org/viewvc?rev=680949&view=rev
4.1.x users should obtain the latest source from svn or apply this patch
which will be included from 4.1.38
http://svn.apache.org/viewvc?rev=680950&view=rev

Example:
For a page that contains:
<%
pageContext.forward("/page2.jsp?somepar=someval&par="+request.getParamet
er("blah"));
%>
an attacker can use:
http://host/page.jsp?blah=/../WEB-INF/web.xml
