DLA-1166-1 tomcat7 -- LTS security update

Date Reported:

07 Nov 2017

Affected Packages:

tomcat7

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2017-12617.

More information:

A remote code execution vulnerability has been discovered in tomcat7.

When HTTP PUT was enabled (e.g., via setting the readonly initialization parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

For Debian 7 Wheezy, these problems have been fixed in version 7.0.28-4+deb7u16.

We recommend that you upgrade your tomcat7 packages.
