DoS

CVE-2014-8937 The api/update.php url is publicly accessible and will run svn update on all registered projects which consumes significant resources and ties up a web server thread. Multiple similtaneous requests to this url will cause resource exhaustion and render the web server inaccessible.

Local credential disclosure

CVE-2014-8938 The svn update function executes with username and password as command line arguments. In shared environments other users may be able to obtain these credentials by running the ps command:

~# ps auxw | grep svn
            www-data 27662  0.0  0.4  12792  3548 ?        S    20:17   0:00 svn checkout  http://host:8888/ ./local/test --revision HEAD --username test --password test

Local path disclosure

CVE-2014-8939 Local path is disclosed by the following urls if php is configured to display warnings: include/smarty/plugins/modifier.date_format.php

Information disclosure

CVE-2014-8940 An attacker can access the /update.log url to view all the projects that have been updated, this can be used to leverage the aforementioned DoS attack or to browse repository code as the projects are checked out to /local/projectname. Example:

~# GET
            http://localhost/vvv/lexiglot/update.log | head -1
            [2014-11-08T11:58:10+01:00] rotateimage
            ~# GET
            http://localhost/vvv/lexiglot/local/rotateimage | head -10
            <title>Index of /vvv/lexiglot/local/rotateimage</title>

            <img src="/icons/folder.gif" alt="[DIR]"> <a href="ar_SA/">ar_SA/</a>
